Printer Spooler Service   Alex
It keeps taking up my entire CPU, clogging the system. I have Windows2000, and I don't know how a printer spooler can use 90+ percent of my CPU for 10+ minutes!   Johnny B
I had this problem on one of our computers. As it turns out, there were print jobs waiting - not on our installed printer - but on Microsoft Image Writer. These print jobs were terminated and all is back to normal.  See also: Link   Dystaxia
unaware of the true reason why my laptop has been slowed to 10 minutes per operation, "spoolsv.exe" persists through my anti-virus scans and stops normal operation in order to re-boot--also with windows 2000.   ben
Careful...This one is a worm...quite typicaly found in your computer...if it is delete immediatly...   JFSU
it's a windows file, it's not a freakin' virus people.   strebor
I'm experiencing the same as Johnny. Spooler is using over 50+ percent of CPU time and there are no print jobs waiting to be spooled.   Annoyed
It's a spooler. When i deleted this file, I don't know why i couldn't boot i had to reinstall windows.   Manu
It's just a windows file. It running in my processes right now and I KNOW it isn't a virus   Bryant
I had the CPU takeover problem, but like Ben said, it was because of print jobs on the Microsoft Office writer, not the actual printer. Go to control panel/printers and faxes and check all printers for waiting jobs.   Tommy
It *could* be a backdoor for hackers. But it is also a valid Windows file. Be careful. This file opened a backdoor and was not detected as the backdoor.ciadoor.b trojan.  See also: Link   Neomonk
Printer spooler - harmless, but it takes surprisingly a lot of memory.   Van
If the spoolsv.exe seems to be causing problems on your computer, you simply have a slow computer. It is NOT a virus, it is installed with Windows and is required for printing. Try defragmenting your hardrives before accusing Windows system process of being viruses. It only uses about 3 MB of RAM on my computer.  
It's a print spooling application, but is easily targeted for spyware and/or worms. I recently removed it from a friends comp. Along with it came several adware bundlers and a king-kong sized headache.   joe
I agree with strebor. It's the Windows print spooler. If it's taking up CPU resources, you probably have a bad printer driver. Delete all the printers from your printers folder, then reboot.   Troy
This file causes no damage as a windows file, However, the filename has been used before by some virii. No threat unless you download a virus.   Gemquist
I had the same problem that Spoolsv was using most of my CPU all the time... but as Dystaxia said there were printjobs waiting on the Microsoft Image Writer, I deleted the print jobs on the Image Writer and now it works fine again   Rieky
It is a necessary file so leave it for gods sake. Variations of the name can be a worm but this actual file is essential for windows to operate.   Paul
It will use some of your ram, but if you run your computer right it will not slow it down really any bit. Mine averages 5,000 K. If you do have a problem do like Tommy said and it should work well.   Nick
Its cloging my system and i dotn even have a printer!   joey
spoolsv.exe is sometimes just a alias and a trojan/backdoor ect ect would be under the covers doing its job. My recommendations is to scan that file for anything   Andy
i don't have any print jobs... i guess it's another windows security flaw being exploited   rick
If located in system32, it's the Windows Print Spooler - which is _safe_ and _not_ a virus! If it's located somewhere else, it's most likely a trojan, trying to fake you with a bogus name.  
Spoolsv.exe is taking 99% of my resources.   Ker
Same problem -100%cpu usage  
Right now, my firewall (Zone Alarm) is warning me that spoolsv.exe is requesting access to the internet!?   Tom Smith
It just take 131MB of my memory.....really annoying  
IT IS a worm or trojan. It is a Windows printer spooler, yeah, but about 5 different types of backdoors name themselves "SPOOLSV.EXE" also. If your task manager shows the normal processes, except they dont have a user name next to them, this could be the problem...   Scott
it took all my cpu, and it was my fault. This file is coordinating your printing/faxing actions. If you are in a network, one printer could have been installed not properly. Also, most of the times it's only the Microsoft Office Image Writer that as a list of prints to do.   Ben
If it's so innocent, why would a print spooler need to acces the internet, for crying out loud?!   Downstrike
I had the same problem with spoolsv.exe taking 100% CPU. A Virus Scan showed me it was infected with Worm.Agobot.30.AP... AVG Antivirus healed the file and now it's all back to normal. By the way, AGOBOT often also infects csrss.exe...  See also: Link   Albux
This program keeps running and using up all my CPU, even after i close it from the task manager. I have not printed anything in the recent past so I believe there is no reason for it to be running and especially to start back up after close it! For now i have put it in Quarantine   Lindsay
The only thing I wold like to know is why a "spooler" has to access the internet? As far as I know, a spooler puts into memory printing jobs so that the printer can print without locking up the computer that is printing. There should be no reason For a " spooler" to need access to the internet.   hacker
My wife activated the MS Office60 day trial version on a brand New HP Athlon 3200+ (hardly a slow computer as suggested) and it loaded MS Office Image Writer (as I found out). Instantly the computer seemed to come to a near stand still. I checked Task Manager and found spoolsv.exe using over 90% cpu usage. I deleted MS Office Image Writer print job... problem solved.   Johnny
It was taking up 98% of my CPU, so after reading these comments I checked the printer waiting list. Sure enough there was something sitting there from yesterday. I tried to remove it but it wouldn't go, until I switched the printer back on. Behold, document no longer in queue, computer back up to speed   Kim
My system was running very slowly, I could not get on Google or any other site. My Windows Task Manager showed that this file was running at 98% of my processes. I ran my virus software, my firewall kept saying this file was trying to access the internet. Once I had cleared the viruses out of my system(MSN introduced) my system ran normally.   Claire Draper
My spool was also running at 100%cpu did research and two reason i found for this was that it could be a virus and it could be a print job in microsoft image writer que. My solution was that there was a print job in the que. I just cancel the job and it was fixed "no more spoolvs.exe running at 100% cpu"   thien
asking zonelabs it says that spoolsv is required so that outlook can access the internet, I have just tested it and it is not true. Well, loads of programs also word.exe tries to access the internet without reason. Just block it.   umm
It occurred due to a failure in a print/fax job, to fix the problem go to: control panel - admin. tools - services ; click on print spooler click stop , give a break (2 mins) then click start and all is ok again :)   Z
This was bugging me for 2 days and then I checked the printer que per suggestion, sure enough there was a test page waiting to be printed... DON'T DELETE THE FILE W/OUT CHECKING PRINT JOBS FIRST!   td
Same problem..it used 97% of my processor, I solved it by getting rid of the print job on microsoft image writer...and now my problems are gone...thanks who ever put that on first.  
Some spoolsv's check the internet for updates - Hewlett Packards especially. You can get a patch from the HP site if you are using an HP printer.   Camelmeister
Found something !!! : Spooler Failure Causes High CPU Usage in the Winlogon.exe and Spoolsv.exe Processes on a Windows 2000 Terminal Server  See also: Link   ND
As mentioned by many others, delete any jobs from the print queues and this will stop the processor from going bezerk.   Hap
Rieky is correct. The MS Image Writer had jobs waiting and I cleared those and now the CPU usage is normal   jobrien
it can be infected with some trojans... Use your antivirus software, update it, and remove this suck   HeyBaby
If it tries to access the 'net/network but you don't have a network printer, it's a bit suspicious.   Anon.
In my case it was a worm with such name that caused a DoS attacks from my computer...   Vic

spoolsv.exe hogging 99% of cpu - the fix. Here's the fix. First, get some breathing room - go to Control Panel, Administrative Tools, Services and stop the Print Spooler. Turn off the printer. Now go to C:\WINDOWS\system32\spool\PRINTERS and delete the files there. I found '00020.SHD' and '00020.SPL'. Now turn your printer back on and restart the service. Check task manager, spoolsv.exe should be at 00%. Whew!   rmann
99% CPU resources were being occupied, we deleted the Office Image Writer print jobs and went back down to 1-2%, problem solved.   Doug
look and the jobs on ur printer   bob
I have an athlon 3400 64 bit 1 gig of ram i DO NOT have a fax or printer or anything of that kind and the spoolsv process is draining alot of my cpu and ive found out it is a virus just trying to find a way of sorting it now...   Ross
I was using windows normally, not sending a print job anywere when my firewall poped up saying "spoolsv.exe is trying to send data to xxx.xxx.xxx.xxx do you wish to allow?". Funny that my printer spooler wants to randomly send information over the internet :D. Nothing was in my printer queue.   R3P1N5
The file "Spoolsv" isn't a virus, go to your printers folder, open de Microsoft office printer, delete the jobs, remove the printer then its done, BUT "Spoolvs" is a trojan, notice that the s and v are turned thats the trojan you ppl talk about   Jeffro
Spooler listens on a given oprt for incoming jobs if you have file and print sharing enabled.   RealityChecker
It can be both. Yes it is a print job spooler, yes its easy to make a trojan with the same name. Figure it out for yourself, run a software firewall at least, and watch the activity. If your print spooler is trying to reach remote IP's at suspicious times (like mine was), I'm willing to guess it's not a print queue.... now you know, and knowing is half the battle. Go joe.   Sgt. Slaughter
We had errors after trying to pring a mail merge that was over 1gb! and the ram was overloaded.   Jdrumstik
please, check if the spoolsv.exe is in the system32 folder (win2k, xp etc) or system fodler (win9x) if a spoolsv.exe is found which is not in those directories then you can start worrying. the spoolsv.exe can hog up the cpu to 100% when invalid printer tasks are waiting somewhere on your pc or network, doesnt have to be in the printer's tasklist itself, but can be as pointed out here already in the Microsoft Office tools (print/scan utilities)   Unz
We've picked one called spoolsvs.exe off two computers, both launching DOS attacks against websites.   Dave
spoolsv took 100% of resources. Found unprinted files   trickyt
It seems to me that if its giving you probs, then just dont let it access the internet and just end process, i know its a pain but in these times its needed   paulos
This problem is easy to fix. Hold Cntrl,Alt and Del till Task manager pops up. Hit the process tab. Highlight Sopoolsv.exe line. Hit end process. Close task manager. Open start, printers and fax. Right click each printer, fax or writer with pending jobs and hit delete all jobs. Once they clear the cpu will be freed. Problem is caused by trying to write to a output device that is not or not properly installed. Don't do that.  
I had a friend who's computer kept freezing and when I checked the processes I found that spoolsv.exe was hogging the proccessor. I stopped the service through Control Panel and that did not help. But canceling all of the Documents out of the Printers did. All is Well now.   Lorin
Its easy to fix the problem of using the CPU for 100%; just delete the print jobs you have in the printer list and you will see that the CPU use is going down to +/- 25% or 10% You don't have to reboot Your PC!!!   Ken
I restarted the print spooler service and CPU dropped back dow to normal.   rmann II
Its easy to fix the problem of using the CPU for 100%  
rmann Thank You Very Much!!! You were right in 100%!!! I've had the same problem with file "spoolsv.exe" blocking all my CPU. I've bought good spyware software to get rid of this problem but it didn't solve the problem. Then I entered this website and risked to do what You've said, because I was in need to restore my laptop CPU power. And it worked perfectly!!!! Thanks once more!!!! Good luck!!!!   Lukasz Tronina
This file causes my Internet Explorer to be blocked. The connections all work and my computer can ping / be pinged, yet my internet doesn't work. After some experimentation, I ended this process tree and now the internet works flawlessly. I searched my hard drive for instances of this. I found 4. 2 of them were windows files (SYSTEM 32 and a SERVICE PACK), but the other two were a bit out of the ordinary. I promptly deleted the other two, and now my system has no problems. =)   HY
The CPU is consumed because your printer is shared on the internet and there is a "virus" outthere that sends print jobs to your computer!!! Solution: disable print sharing!   Michel Turcotte, author of Win-Hand at "MT Impossible"
was having the same cpu until problem as others, constant 50%. went to printers, open ms image writer printer, sure enough 2 files waiting to print i didnt know about. cancelled them, cpu util for spoolsv.exe went to zero. try it.   z
Here is a BAT file 1st line (net stop spooler) 2nd line (del /q %systemroot%\system32\spool\printers\*.*) 3rd line (net start spooler )   JOE
Definitely a virus, use http://housecall.trendmicro.com/housecall/start_corp.asp to scan it if you're having this problem.   T
The "W32.Spybot.Worm" virus takes a similiar name "Spoolscv.exe" in system32 folder. Compare with the normal processes of Windows when power up will see the problem. Check out Symantec web site   Ben
See the note. Search the file and look at its properties. MS Spooler server is ok, anything else is not. If it is the Spoolerserver, a propable cause is the driver for a disconnected printer (notably HP) still polling said printer. Uninstall the driver and you'll be fine.   Victor
What's the deal with it trying to access the internet... I've been a bit cautious for the past few weeks because I had a few trojans on my CPU... If somebody could tell me why this is happening cos' I don't believe that it's due to my printer (Lexmark 1100 series)   Tumppi

it's annoying me. my kaspersky av program finds worm.win31.soriw in the spooler directory. and spooler.exe dominates my cpu usage. i can't get rid of this file or whatever it is! another windows silly pack problem i thing !!!   Ersin
I had the same problem and I found out that the Microsoft Image Writer was trying to print a doc. Delete that doc and everything is back to normal.   Dumi
I have fixed this problem a few times myself. I basically went and deleted all printers within the print spool folder and then I change the registry. I had to modify the spooler in the registry I just change the 2 to a 0 and rebooted then went back in a modified it back to 2 to start the service again and everything was fine again and the problem hasn't come back.   trobinson
my computer is clogging 99% recurses, too   eagle
It makes a PC slower than Timex2048. It is indeed a threat.Still. I don't know what is the extent of the damages besides CPU overusage.   Velut Umbra
Spyware - It just keeps the cpu usage under 100%. If u kill the process, it will restart after a couple minutes. im still trying to find a way of destroying it, since all antivirus i tried dont detect it as a virus  
Dunno what it is but all my prog working on it, my blackice detected it. And it keeps to try sending emails. I think its a worm...   yannickvdb

It is a windows file. I get the CPU hogging problem only when using one program (Print Shop) to send labels to the printer. I can get the machine working again by going to the winnt/sys32/spools/printer folder and deleting the files there. It doesn't explain however why the problem is occuring. I am doing more research to see why this can happen.   jbdiver
It is a windows file.   jbdiver
increases cpu space to 99% if not terminated. id like to thank RMANN for his comment. it worked! now my cpu isnt running at 100 percent now, and my printer now works. thanks alot   martin mika
A client's Task Manager showed spoolsv.exe using 95-98% cpu usage. I deleted a MS Office Image Writer print job and problem solved!   Ken
I want to thank everyone for the info. My new (2 days) machine suddenly start behaving like a 60 meg W31 machine. Found this site and checked and lo and behold I had 3 print jobs in the que. Don't even know how they got there, since I hadn't installed a printer yet. But it was using 98-99% of my 2.5g cpu. Again THANKS   EdC

A realy microsoft fioe and problem, a program accidentally sent a job to the Microsoft image printer (or fax), spoolsv.exe took 50%-100% cpu, even after reboots. Cancelled all print jobs for all printers (one at a time) fixed the problem   Jack Feder
Those having computers running Spoolsv.exe between 90% to 99% CPU usage: I have been told it may be a virus or malware. I checked and rechecked and my system was clean. I found an artical that advised there may be something "jamming" up the printer spooler. The article advised to 1. Turn off the Print Spooler in Services 2. Turn off the printer 3. delete all files in folder C:\WINDOWS\System32\Spool\Printers such as '000x0.SHD or 000x0.SPL'. 4. Restart the Printer Spooler in Services. This resolved my issue.   Nathan W.
this process can be securely turned off and on again if u will use ur printer. by control panel, administrator settings, services, select printer spooling and make that stop or disabled.   ccresanto
MAKE SURE it is "spoolsv.exe" and NOT "spoolv.exe" - that's causing the slowdown because "spoolv.exe" is a virus  See also: Link   Paul V.
if the file is located in c:\windows\System32 then its safe and required for print jobs, if its located anywhere else its a trojan, virus, keylogger etc.   Bruiser
It's not harmful, although I suffered the CPU takeover problem - I deleted a print job in the Microsoft Office Document Image Writer and everytihng returned to normal.   Tomas
Using XP Pro. I had 100% utilisation Only after printing. By looking at each printer i found a corrupt print driver. Was unable to remove it as it caused 100% utilisation every time it was clicked on, so had to manually remove. Unable to follow Microsoft example of removal, as drivers were 'in use'. So disabled the spoolsrv service, restarted and manually removed the registry entries as per Microsoft instructions (see Link). After restart, made spoolsrv an auto start service and had no problems since. My PC has a new lease of life !  See also: Link   snowy

it is part of the OS in normal circumstances, if there are outsatnding print jobs on any device it uses up loads of cpu   Rob
Had the same issue, Due to M S Image printer, Deleted awaiting print job, solved the issue, Cheers Guys!   Ben
if u dont want it just disable the printer spooler service, but it would be easier to cancel any jobs waiting to be printed   SZ
First use a system search and type in spoolsv.exe. If it shows up anywhere besides systems 32 or whatever then delete it.   k
can I just delete all instances of this process. I don't print or fax anything off this box and I keep seeing instances of it running.  
screw it. i odnt have any printers installed

it is taking up all my cpu and i have a good comp   Bob
This consume sometimes more than b 90% /b of CPU usage and slow down your system. End task this process if no printing job is in que.   Amit
It's a print spooler. If it's clogging up your CPU, check all your printer connections for waiting jobs, especially networked printers.   Strebor Ekim
This program only takes up about 600 K of memory on my system and uses almost no CPU power. It shouldn't be hogging up all the resources!   Core Master
It was not a virus in my case, print jobs waiting. When I cleared print jobs in Microsoft Office Image Document Writer, CPU util% went to 0   Sung
i found it in my Microsoft Image Writer from one of the guest computers on my network - no dramas - just delete the print job & the problem goes away - all fixed :)   Rick Spitzbart
This file took up all my CPU space I don't even own a printer! Once I deleted it, it freed all the space again. Persisted for a while, but then disappeared totally.   Maximus
To avoid the large cpu usage of the spoolv file.. simply go to the properties of the printer and turn off spooling and have the documents sent directly to the printer.   James
Very Suspicious: always trying to connect to the Internet (zone alarm detected), changing itself and worse: - It comes back after I have deleted from both system32 and ServicePackFiles/i386.   LEK
when is using 100%+- of your processor is because the print processor is halted. Just go to services and stop/start the print spool service. Then you will be able to delete the stucked jobs.   bandolex.
As mentioned by every one it is a Windows file. Pretty much a valid file. I looked for pending print/fax jobs and cancelled the job. Everything was back to normal.   Greg
I had a document running in microsoft image writer and was taking up loads of cpu. Deleted document in queue and all is calm. In fact, I deleted ms image writer as a printer!   Styler
trojan, virus- do a search on your system for spoolsv.exe. There should only be one account of this file in the system32 folder. If there is another that is your trojan- DELETE the sucker!!   Emma
trojon, virus   Emma
Can be dangerous. It is used for spooling prints but there is also a trojan ciadoor backdoor viruse that uses the same name. But if it is going really slow that doesn't mean delete it because the normal spoolsv.exe can slow things down substancially if something that was waiting to be printed was canceled. So get something to scan it with and if it says its a problem get rid of it.   Chris
if you are on a windows 2000 server and its going to slow open your printer folder you can go to services and stop and restart the printer spooler   seb

some printers access "the internet" to print or connect to the printer, they are not really accessing the internet but my HP 3030 gives itself a port on localhost (eg: localhost:1234) zonealarm and firewalls like that think "oh crap and warn you" i have plentl of other things like a pocket PC that also bringsup a warning in zonealarm.   tim
90 % of the time its unprinted documents in the print que and you can fix it by just cancelling all documents for all printers installed. Youll have to put up with slow computer and start the spooler again (start, run, net start spooler) go to printers folder, r click on each printer and cancel all docs. If that doesnt work, then yes you have the trojan. A good spyware program will remove it.   ShadowShot

I found this file to be taking up alot of resources. It was down to 8 print jobs being stuck in a print queue. I removed these jobs and now everything is back to normal. Check this before worrying about Virus/Spyware.   BendITmorE
Search for the file and find where it is located on your system. If the file is in the Windows\System32 directory (XP) and is about 56.5KB ins size it's OK. Check your print jobs.It also appears in the Windows\$NtServicePackUninstall$ directory and Windows\ServicePackFiles\i386 directory on my system. These are all identical file sizes. Anywhere else is probably a virus.   Jay
probably just a Windows file but it slows the system better have the .bat "BAT file 1st line (net stop spooler) 2nd line (del /q %systemroot%\system32\spool\printers\*.*) 3rd line (net start spooler ) " on your desktop to click it and speed up your system when spoolsv goes 100%   suaritos
it keeps on taking my 100% of CPU unless i cancel it. but it still comes back   chandan
spooler.exe and spoolsv.exe are not the same. The spooler.exe is a virus, even symantec finds it as a virus.   MrGrey
definitely, absolutely a virus which blocks internet explorer,freezes the machine,and prevents to restart or shutdown.U cant easily delete it,or just prevent it by disabeling printer share from the services..I am gonna try Ramnan's advise..   xazal21
I had the same problem on Win2KServer, as suggested by rmann, go to C:\WINDOWS\system32\spool\PRINTERS and delete the files there. It works fine now   KS
it can be a virus. However in my case, it is not. like some people said check all of ur printer physical and virtual, mostly virtual ones like microsoft office documents there will be job waiting to print. and to make sure scan your computer.   fake
spoolsv.exe is growing in size each time I print a job. During the day it grows upto 500 Mb Ram before i delete it and reboot. We are currently deleting the file and rebooting at least once a day.   edd2edd
"spoolsv.exe" is a windows built-in service for managing the printing jobs and operations. If you don't use a printer, it's better to remove/stop this service.   Xoy

It continues to build, 2 days ago had 3 *.spl files at about 3GB each, had 1 today at 8gb.  
Follwed the advice of those who said there were pending print jobs. Click on EVERY printer you have listed and delete the pending jobs. Worked instantly for me. Thanks.   Ray P
I deleted the print jobs from the factory and now everything is running great.   Vicki
I had 100% cpu usage by spoolsv.exe lasting 5+ mins for each print job.. As suggested above, I went into Control Panel, Admin Services, services, and stopped spoolsv.exe, then restarted it. Problem seems to have disappeared for now.   Tom
spoolsv.exe is a valid Windows file, however, there are virus out there that will spoof themselfs as the service. First check ALL your installed printers for print jobs... I have seen the "Mirosoft Image Writer" issue stated above (where the print jobs are waiting in the Microsoft Image Write queue). Next, make sure the file is in the C:\%windir%\system32\spoolsv.exe, otherwise it may be a virus.   Working on it
It causes alot of problem for something that's quick to dort out when you know what to do   Malcolm Gilks

This is the Print Spooler Service, do not delete. you need it to print stuff   zawetzel13
Either the Windows' print spooler, or a virus disguised. There are several viruses that call themselves SPOOLSV.EXE in order to confuse the infectee. Please do not dismiss odd activity from this process, BUT be sure that you are infected before deleting essential Windows files!   White Hawk
I have 2 1 in the C/windows/system32, the other in c/windows/servicepackfiles/i386, I think the second one is also valid...   weedmonkey
Deleted several extra printers I had installed, and removed all pending print jobs... Spoolv.exe no longer takes 100% cpu time.   Darkwing
Spoolsv.exe is a system executable for the printer, but having multiple or if the executable(s) are eating 90% to all your resources than you better scan your comp for viruses and check the registry to make sure nothing funky is there.   1337Nerd
If spoolsv.exe is taking too much memory, its simply because there are printing jobs waiting. Just go to the printers/faxes area and delete all the files waiting to be printed.   Joed-Up
It manages the printer and fax spools. I have WIN XP and it took more than 90% of my CPU. Do not delete file, first review the root cause. As Distaxia and Tommy finally concluded : Go to the control panel for printer and faxes and cancel the pending jobs. In my case it was for MS Image Writer pending "Print" file.   Miguel
Using 98% CPU. Went back to normal after turning the printer on.   larryw
Bottom line this could be a harmless Windows file or it could be a worm/trojan. Check the file and the spooler settings before making judgement!   Harry
On my comp it is not a Virus or a file waiting to be printed. Nobody has ever given an answer on how to fix this if it is neither.   qwad
Mine was using 100% CPU!! Checked the printer and there was one print job waiting, cancelled it, and cpu went down to 4%!!   V
Its a print spooler, really this file is creating problem eating up all the CPU almost to 90% , though there is no document pending for printing... I believe it is trojan horse or virus needs to be checked with updated antivirus   Mohammed. Siddiq
Everybody READ, look at your processes, there may be two of the spoolsv. One of the ones on mine was spooIsv (the I is an i). I got rid of it and everything seems to be running good.   angus
This spyware over write spoolsv.exe with the same number of KB. The only way that you will know that it is on your computer is with a good spyware program like Xsoftspy. Windows will not let you delete it so you will have to over write it from your Reinstallation CD or copy from another computer service pack 2 will not work on service pack 1 (FYI)   Larry Powell
It wont let me change my background it is just balck at the moment.when i try to delete it,it comes back in about 10 seconds.   david
Windows Print Spooler, consumes all CPU %. This nasty little bugger has burned out hardware (CPU/MB) that was running well within spec.   bluescreen
If spoolsv.exe is in the windows/syste32 folder all is well but if it is somewhere else (as in my case) it caused problems. I renamed it to spoolsv0.exe and the problem went away.   Steve
Print Spooler - A Service When I open up Word, it takes up to 15mins to open a simple document with no pictures or header, when I disable the spoolsv the actual document just opens up fine but won't be able to print coz the spoolsv is disable. so I enable the service again, same thing the document just takes forever. but I can see the printer and print from. Its so frustrating and help!   Jenny
Xoftspy (anti-spyware program) detected it as a trojan and i simply booted in safe mode and deleted this file. when i booted to normal the file didn't appear anymore. at this point I don't have spoolsv.exe on my system and my pc still works great. (i don't have a printer so i don't care).   GanniKill
window file sure behaves like a virus   M
I had the problem (on XP Pro) of this process using 50% CPU. I had earlier tried to print from another computer on my network to a printer attached to my main XP machine. I printed from Word. The print seemed to go through (the print queue icon in the system tray appeared then disappeared on the remote machine), but nothing printed. Following the advice of others, I checked my Printers settings, found the MSO Image Writer, right-clicked and cancelled all print jobs. Solved the problem.   garyzim
I had this file taking up 98% CPU and after running a virus scan i deleted the microsoft image writer and rebooted and now all is completely fine with PC.   Jo
It was not a virus in my case, print jobs waiting. When I cleared print jobs in Microsoft Office Image Document Writer, CPU util% went to 0   Chris Yeowell
I once thought that this is one of the file from Norton Antivirus, because it's taking up my CPU and slowing down my PC. I delete 4 unused printers driver and now it's not giving my any probleem at all.   Joe
In my case this also was using 95% of CPU, just because there was a waiting job for a phantom Image Writer! Deleted the job and all was well.   Liisa
it is a windows file, not a virus or spyware... the only thing is that, when I close the process (I close all unuseful processes on startup, because I have many), I can't restart it... so when I want to print something I have to restart my pc   LordCorkscrew
This problem happen when you have some virtual printer or fax viewer and you or somebody printed a file with those printers and some pages are in queue of those virtual printers  See also: Link   Omid Kosari
It is causing popups on my computer.   ej
I get that it's just a windows process to do with print jobs if it's in the right folder - but why does it need to access the internet?   Sasja
My laptop was in a holt, as "spoolsv.exe" was taking 98% of CPU. It was due to few pending print jobs in a printer. I tried to delete them. All but one got deleted. As suggested elsewhere here, to delete this last print job, I had to go to Start Control Panel Administrative Tools Serrvices and then selected "Print Spooler" to STOP it. Waited for 2/3 mins and STARTed it. Now saw, the left out print file was deleted. Everything is fine now. If this is the case with you, then fine (and lucky). Otherwise, do as others who considered it as virus/trojan, suggested here.   Syamal
Could be one of 4 Trojans/viruses/worms - Backdoor.Ciadoor.B or VBS.Masscal.Worm or Hacktool.Privshell or Graybird.A. Symantec tells you how to remove all but Graybird (that one at Sophos). It is also the printer spooler. For me it took 99-100% of my resources all of a sudden. Turns out THE ANSWER WAS IN THIS THREAD. Delete the document in the print queue of Microsoft Office Document Image Writer, and the problem will be solved. Thank you Sung. Should have read your comment days ago.  
this file causes as many as headache i can take... At first everithing was normal and then after I installed a Antivirus-programm it began to slow my computer all the time i use it... So i had to close it each time i starting my PC with Win XP (I have a AMD Athlon XP 1800+, 256 MB-DDR) this procedure takes 3 times, because this data starts new after i close it... And I havent any Internet-Connection on my PC!! So theres no Virus etc. MFG, CeeJay D-Magic   CeeJay D-Magic
Spooling is ok as far as os spooler function is concerned but what i got is that any program that were taking merely 2 to 3 seconds now takes more time plus the machine seems to be not responding.What i did is searched the spoolsv.exe fine and delete all it's related components and did a complete pc restart.it's now working fine   Hazarika
The file is from microsoft Windows, anyway I used Xsoftspy (detector for spyware) and it gave me the following: Vendor: Proxy-Agent.g / Type: File / Category: Trojan / Object: C:\Windows\System32\spoolsv.exe / Danger: Threat / Object Details: Unexpected connections to the ip range of 204.209.184, attempts to disable AV software.   Burns

spoolsv.exe using 100% on re-boot and when trying to print. Every time I cleared the print spool and closed the process it returned. After running about 7 virus scans (Norton, Mcafee, trend..etc) no virus found. Turned out to be HP5500 printer installed incorrecty, uninstalled printer, after re-install all working fine.   Tom
spoolsv.exe is a Windows operation bundled with a trojan/spyware. I kill the process each time I start. It is programmed to restart 3 times. After that no need to worry (until next start-up). Then...hence the 3 time rule again and again and well, you get the hint.   B.R.A.S.H.
I can't shut it down from taskmanager! Since my computer was on, Pop-ups never end! That's ridiculous! I can't get it out from Microsoft Anti-Spyware + ad-aware + PC-cillin + Symantic Anti-Virus. Even I've updated some of 'em.   samson
I just wanted to thank everyone for the coments. My computer was running so slow. I looked and I had a print job waiting to be printed. I deleted the job and now everything is going fast again.. thanks for everyones help.   Dondie
my pc takes around 10 minutes to start and would sometimes reboot itself. thanks to rmann's tip, i followed his advice and the cpu usage went down to 1-3%   ana
Check all your printers... I'm sure you have a print job stuck somewhere... Drove me crazy... 3 stuck on Imagewriter.. deleted them and it cleared up   Robbie
The suggestion above to go to Admin/Services/Print Spooler and start/stop it was exactly what I needed. It was taking up 120meg but now only 11.   Mikey
Takes 90+ CPU usage. Slow Processing , Impossible to play games or even acces the internet while it's running . How can it be shutdown forever ?   Vega
Spoolsv.exe isn't causing me a roblem, but spoolsov.exe and spoolshv.exe are. They appear to be performing mail relaying business. Not good.   Mags
If you disconnect your printer and print something, it will take up about 90% of your CPU usage!  
i cannot delet this file at all. even i do it , it will recover immiediately.  
99% CPU useage Fixed when canceled MS ofice image print jobs   RobertW
it spools any q-jobs either to printer or fax etc.   utpal
it just takes all of my CPU up to 100%   ??

Even when I kept clicking Block Always, my Norton Internet Security would keep popping up a warning that Microsoft Printer Spooler Service was trying to access the Internet. I wasn't trying to do File Transfers or Print Sharing, so I didn't need for it to access the Internet. In order to block its internet access, I followed these steps: Open Norton Internet Security, click Personal Firewall, click Configure, click Programs, scroll to Microsoft Printer Spooler Service, make sure that Internet Access is set to Block All and that the Category is set to File Transfer. Click OK.   Jean
I am a computer programmer and I am positive I know what i'm talking about....Spoolsv is not a dangerous file it commonly used for printing, it can also slow down your computers performance and terminating this will not cause any slowing or trouble. the best way to terminate is to press Ctrl + Alt + Delete then click the Processes button and click on "Spoolsv .exe" click "end process" will make you computer run more efficiently. If you have any questions feel free to email me at "gtarskater@yahoo.com"   Ben White
there are two immages with that name: one is safe and should be kept if you have it, because it works with your printer: the other kind is a known back door that allows hackers to steal information and put information on your computer, the reason you see strange activity comming from this immage is that a virus or a hacker is using that to do its dirty work. thus it is not a virus, but a open door that hackers and viruses use to access your computer  See also: Link   Dustin
I don't know anything about this file. From all the comments i have read it seems i have had a virus type. I would leave the computer for a couple of hours as i realised that it was working (fast) but it was doing everything so slow because of it. By the tmie i came back from doing nothing, it used 50mb of sending and recieving. Deleted the file, and it's good to see the 'connected to the internet' icon not continuously lit up. (yeah, go dialup!!)   Collins
Doesn't work well with lexmark printers and adobe version 7.0 reader if the reader isn't the actual full adobe suite. The downloaded adobe reader turns the spoolsv.exe file off so you don't have a printer any more. you have to turn the windows spooler back on - evrytimee after you use the adobe reader.   Ralph Kelley
i have 5 computers. 2 of them wont print unless spoolsv.exe is enabled and can freely access the internet. if i block it with zone alarm, the document wont print. evertime i print it appears to go online uploading and downloading somth. this has pissed me (a-lilbit) off for 2 years now.   sookme
Like Tommy I had the CPU takeover problem, it was because of print jobs on the MICROSOFT OFFICE WRITER, not the standard printer. To solve this problem go to CONTROL PANEL/PRINTERS AND FAXES and check all printers for waiting jobs. If any job waiting, cancel it.So itīs solved!!   Alfred
my pc crashed twice then after a microsoft update my pc said that spoolsv.exe had changed and wanted to get on the internet.. so i said no, checked it out- came here and relised my cpu was at 80 so i went on my firewall and blocked a few projrams and its between 10-49 now...  
i dont even have any printers or fax connected to my CPU!! this shit using up to 99% my cpu usage!! i just noticed it.. because i was trying everything to find wat was casung my pc to slow down .. so dam slow! i cant even serv my files on the irc!!~   hellboy
Spoolsv.exe is just a file that keeps windows to print stuff, if you have a wireless network or so or cancelled a print job but didnt do it properly and then turned off your printer this is the problem. just turn back on your printer   timbo
tried multiple spy/virus checkers, everything else recommended by HP; found file in image writer, deleted it and now I'm fine. don't know what it is or who created it, but it sure caused a lot of worry til I saw this site!! thanks   flyan
In my tasklist is spooler.exe and spoolsv.exe. Spooler.exe is taking about 50 untill 60% CPU. I havent got MS image writer. And no printer installed. And i cant find any print jobs undone. And where can i turn off the spooler?   AvolA
This is defenitly not a virus when you start windows, but there are viruses that attach, keep a close eye on it, and keep it clean, other than that, you should be ok, mine is really virused up, it starts when IE does... BAH!   Paul
Not a virus. Just check printers and faxes in the control panel and see if your system is detecting your printer. I have two printers and one was not showing after a botched print job. Quick reinstall and everything fine.   Tim
I get a spoolsv.exe error occasionally and it deletes all my printers I've found spoolsv.exe in for locations on the computer including system32 and Ntservicepack folders should it be installe din four places?  
MAY be something corrupted after cleaning against of viruses I get Task Manager kill the process and in the %system% renamed this file after xp installation ask me for insert disk and write new spoolsv.exe   Dmitryu
When terminated it fixed a bug that froze my macine for half a second every 7 seconds (word and freehand only). When I then changed a printer setting (spool directly to printer) the problem was fixed.   Shaun Lee
Well my norton internet security keeps asking if i want to let it access the internet, i said always allow, then never allow, and it just keeps popping up over and over again? What does this mean?  
Its safe aslong as its in the right folder. and the acses to the internet is windows looking for lan printers.... And if it consumes alot off cpu then you are doing something wrong with your pc   ghezus
I had this taking up 98% of CPU and it turned out that there were 13 jobs queued to the Microsoft Document Image Writer. Cancelled all these and deleted the "printer" and no more worries.   Scott
if you have a good firewall keep spoolsv.exe from accesing the internet.you have now blocked a possible backdoor hack.I recomend Kaspersky or Zone Alarm 5...pro   Christian Pierce
As others said above, the cpu load issue was related to my printing of a (!!!) 1.36 GB job!!!! (just a 26 page pdf file... why it was so big who knows...)   apoc
I had a job with status of printing in que for Microsoft Image Writer that caused this. Canceled the job and cpu usage instantly dropped. Thanks, Omid.   WSS
it's true!!it isn't dangerous.check yours printers and find the problem: Microsoft Office Image Document Writer; no spyware no virus   massi
I have 4 spoolsv.exe on my machine. One in Windows\ststem32 and three in Windows\Software ditribution\Download\ - Alert?   ? kenmat

I just had SPOOLSV.EXE taking up most of my cpu. I cancelled that job and now have spoolsv.exe running but taking up virtually no cpu - looks like the one in capitals is the one to watch out for, the lower case version is probably the windows spooler.

A user on my network is having this issue with one of her printers. HPLJ4100N..if this is set to default the cou spikes over 90%. When not default it is fine. No virus or spyware found, updated the printer driver from hp.com, cleared cache, and extra drivers..Still no luck.   laytonjp
Increases CPU usage by 90 +%. To fix, first delete all pending print jobs in the print queue. Next, go to Control Panel, Administrative Tools, Services, and restart the service. Problem fixed.   Rich
spoolsv was using 100% of CPU. Turned printer on and off and usage goes down to 0%. Don't know why but it worked   Harry
It's a print spooler. It shouldn't need to access the Internet, but it tries. Does anyone know why?   MuyGordo
A valid Win file, which can always be a duped. However, print spooling is not needed. You can turn off printer spooling in printer properties.   Christian K.
Yeah it uses a considerable memory, the norton antivirus detects it as a hacktool   Falo
It might be poorly made, but it's not dangerous. Only the trojan process is dangerous.   Jumblock

I uninstalled my pdf printer...cutepdf. Now my 99% spoolsv.exe just went to 3%.   rimmer59
Look, my system was very slow and I did not set up anything to print. However, I checked my printers and someone in my home had 5 items in cue. I cancelled them all and now spoolsv is just fine. System runnin' like ConRail...no wait, that's not a good example...   Dez
Its just a print spooler, Those having computers running Spoolsv.exe between 90% to 99% CPU usage: I have been told it may be a virus or malware. I checked and rechecked and my system was clean. I found an artical that advised there may be something "jamming" up the printer spooler. The article advised to 1. Turn off the Print Spooler in Services 2. Turn off the printer 3. delete all files in folder C:\WINDOWS\System32\Spool\Printers such as '000x0.SHD or 000x0.SPL'. 4. Restart the Printer Spooler in Services. This resolved my issue.   M. Atif Farid
Previously I had lpt1 and lpt2; I removed lpt2 but one DBASE application still printed to it--Result the spooler clogged up. I fixed the source of the problem which was the old DBASE program printing to a good printer at a now non-existent printer port   wolfi

spoolsv.exe is a Microsoft Windows system executable which handles the printing process to your local printers.   Alex,sun Taiwan
This is a Windows File - In my case it was when I installed a Anti-Virus (Panda). After removing it the cpu was normal. Tryed to reinstall Panda again, and I got the same result. Being so there is s aconflit with spoolsv and my antivirus.   Jorge

A file named spoolsv.exe can be used by a hacker to access your personal information on a pc and create a cmdshell with elevated privileges, allowing a user that does not have Administrative rights to obtain them.,,at first hacker will try many tools to enter your PC, ZoneAlarm Pro may help you to protect but be aware it may not help some times,a hacker may target users who are working with CPU.exe or FTP server, telnet, and ... ,onfigure your email server to block or remove email that contains file attachments that are commonly used to spread viruses, such as .vbs, .bat, .exe, .pif and .scr files.   Amir
Warning: I just found an Executable called spoollv. This is NOT the Printer spooler, it's a Virus   Tyron
It slow done all of my pocesses. If i try to delete it, it simply returns. When I close it the system works fine, however sometimes it cannot be closed.   Jeff
This file is commonly for windows print jobs, but it CAN be a trojan infected file that opens back door so kill it in task manager and if u need to print reboot use it then kill it just to be safe   Joe
So, why if this is an innocous file is it always trying to access the internet from my PC? Especially as I don't have a printer installed.   NRM

Its both, definetly a windows service + could be a virus. If it is taking up a LOT of your CPU usage when you are doing NOTHING, then delete it right now!!! If its not taking up so much cpu usage, then leave it alone.  
My Mcafee VirusScan just notified me that it had changed since I accessed the internet thru dial up. It asked if I wanted to grant it further access to the internet. The file was in the right folders, and worded correctly, but I blocked access.   Steven
Funny thing is I don't have any printers and I can't get rid of this thing.   X13

Printer Spooler Service: After checking the printer queue I found unprocessed print jobs. Deleted the print jobs and CPU usages returned to normal..   Johnny
This file is the Printer Spooler Service - It should run zero-cpu-time - It can be hang on computer by printing, because this process converts the data in printable sigs - 99 % CPU in priting mode - this process is maybe requesting to the internet, because it also handles network-printer   cyrus
Unsure of the legitimacy of the file? Do a search and note it's location. If your spoolsv.exe file is NOT located in your Winnt or System32 folder, it's probably a nasty file. However, even if it is the legit Windows file, there is NO harm in ending the process, provided you don't plan on printing anything. I have no printers installed on my PC and there is never anything in my print queue. Despite this, spoolsv.exe uses up a lot of my so I don't ever need to have that process running.   MS Loather

In my case there were files waiting in the MS image writer in the print queue. I was unable to delete them, however, so followed advice and link from ND, above. After turning off the print spooler as directed (control panel, administrative tools, services, stop print spooler); turning off the printer; going to C:\WINDOWS\system32\spool\printers and deleting the files I found there; turning the printer back on; restarting the service; I found spoolsv.exe to be running at 0% on task manager!!   Groove

Spoolsv.exe used 100% och my CPU amd 3700+ 1gb RAM it was caused by the fact that microsoft office created an printer which I could not empty when I had shut down Spoolsv.exe so i had to wait while the darn used the entire system until it finaly loaded the printer menu and i could empty the printe file - a rather easy task took me about two days .... ;-) Thanks for your support   Pontus
Some people need to learn the difference between a kilobyte and a megabyte  
This file is your printer's current processing. If your printer is currently pending something and your printer is not connected, it will take up approx. 97-100% of ur CPU. If your printer is currently doing something, then this will take up a lot of space.   Aslee
Doesnt do anythin.. Just eat your memory  
This is a windows system file. If it is getting all cpu resources, probably you have a printers/fax configuration problem.   Osvaldo

Can either be Windows printer spool service or a backdoor trojan, depending on the location of the file. If it is running from C:\Windows\system 32 it's not a problem. If it runs from anywhere else, delete it.   PowerPlay
I always solve the CPU usage problem by deleting the process in the Task Manager. Often I"ll be playing a game or something and the computer slows down to 10%. I don't think the file is a virus in itself, but it isn't written properly or it is bugged somehow w/ a leak so that it can take up too much CPU. As I said, terminating the process in Task manager when it acts up works fine.   Artanis
In my case, it eats almost all of my cpu. If I end the process within Windows Task Manager, all problems go away. But, from what I hear, it is also a print file. I would only delet it if your system returns to normal after ending the process (search your system).   Fiska (Feb 9 2006)

This SHOULD NOT use your CPU if you are not printing, but a worm can "Hijack" this name and it depends on what it is doing, if it only works while you are printing you are fine, if it is running when you arn't using the printer you should end process, it is always safe to end process, cause if anything goes wrong, you can reboot your computer and it will be back there (this is for any program)   Printer/Worm
Its a Windows Printer/Fax File, and you don't have to have a printer or fax machine installed on your sytem for it to take your CPU usage up! Your Windows PC's have the Microsoft Office Document and Image Writer on them in the Printer and Fax folder in the settings folder. Go into that and delete all of your printing jobs you have in their, because they'll never print, cause you don't have a printer, even if you do have a printer, they still won't print! Just delete the Image writer itself, you don't really need it at all, Microsoft just loves to waste space.  See also: Link   Mr. Wise
spoolsy.exe is standard system print spooler for windows. Watch for hung print jobs. Keep in mind that if the spoolsv.exe file is showing up in %systemroot%\$NTUNINSTALL type locations, that if a trojan or virus has infected you, it could have imbedded itself in the uninstaller folders for your service packs and your system restore folders in WIN XP.  
This file is used for windows print jobs. I was looking for a solution to fix this problem thinking this to be Trojan. After reading through the suggestions made on this site, I checked the Microsoft Image writer & sure there were three large files waiting to be printed. Once I deleted those, problem was solved. Thanks for the people who put their experience on this site first.   Kiran
It spools print jobs for a printer or image writer. If it is taking up too much memory it is becasue there is a print job that is not properly being processed. Open your Printers on the control panel and cancel outstadning jobs. Your memory usage should return to normal   CJH
Can have errors, remove from task list if it is slowing your computer down.   Kent
My spooler was taking up resourses also. Up to 80%. I didn't have any print jobs waiting that I knew of. But there it was. I would delete it and it would come back in a few mins doing the same thing. I then checked one of my other printers that I had installed but not currently using. Bam! there was a print job waiting on one of the other printers. I deleted it and no more spooler hogging my resourses......   Bigjeep
this process is a normal windows process, but other viruses and malware have the same name, and if you look in windows task manager, it will show that it doesn't use a lot of memory (mine is less than 2k) but if it does (i saw another process with the same name, taking up 20k), it could possibly be a virus.   #1
irritating hopfully not in windows vista   wva
It seemed respossible for massive CUP usage, then I checked and my printer was unplugged. I plugged it back in and the cpu use instantly went back to normal. Check the basics first I guess   Kinb Boy B
I was also spooked by this file for almost a month. Thought it was a virus or something. Was planning to format my PC. But then I read a few of these threaded articles and then went to my printer status window and found that indeed 1 had 4 print job in queue for the Microsoft Image Writer. Simply deleted them and WOW - its alive...... My computer came back to life..... Pretty harmless but a sure shot frustration generator.... Wonder why Microsoft hasnt patched the loop hole yet....   Rohit Chawla (India).
*If its using a high amount of your CPU* Start - Control Panel - Classic View (on the top left) - Administrative Tools - Services - Find "Print Spooler" - Click Stop - PROBLEM SOLVED!   Jon
I did as said and deleted all outstanding print jobs. CPU Utilization went to 0 and all is now working great.   Justin
When my PC run very slow I look at Task Manage and I saw it.   Lovethe
Recently Installed CA, AV& ETrust Firewall Apps Whenever I attempt to go online the software asks for permission (Allow/Deny) The Destination IP is 24.29.103.10:DNS If I don't allow no Internet access is allowed! It is a MS Application so you wise guys should have some idea of whats happening here.   Blackstar ISS
It is a Windows file to control printers and faxes. If you get high CPU rate for this executable it is an operating system problem, then try to stop and restart spooler service.   Edgar
I'm running Windows XP and during routine stuff like running Excel or something, it will tie up like 75% of my processor...that shouldn't happen. I have even deleted it from the System32 folder, and it keeps coming back.   kmax
according to Symantic Security Response spoolsv.exe is a legitimat Windows file that the "Backdoor.Ciadoor.B" Trojan uses to invade your system. When that happens the good spoolsv.exe changes to the evil spoolsv.exe. So it looks like all of the comments so far have been right.   cbruce
I had this problem, but when i turned my printer on, and it started printing the jobs in queue, the pc ran normally again.   Danboy06
If it's just a matter of the file bogging down your computer, go to your printers in the control panel and make sure none of them (even the Microsoft Image Writer that ALL Windows machines have!) have any documents waiting to be printed. This simple task cleared my computer up by about 88%. (It was constantly stuck at 100.)   Carl
Only when I print it uses the CPU and more than 4k mem.   Al
Going to the printers and deleting all the outstanding jobs did it for me. The culprit was hiding in Microsoft Office Document Image Writer. I am so glad I found this page before I trashed my pc having had it running at 100% for the past 2 months.   Nicholas
This handles printing and print spooling (queuing). Print Spooler uses it to load files to memory for later printing.   Maur
Cheers everyone that mentioned about the print jobs still outstanding. Really appreciated!!......well worked for me anyway   Chris
spoolsv.exe is a windows system file for printing purposes and it will definitely cause problem if you have printing pending otherwise it's a virus.   iconoclasticrisx
Printer/Fax spooler: To view or disable process, use Task Manager, (Ctrl-Alt-Del in WinXP), You can test this way for mem activity   Diomedes
I just had the problem of csrss and spool using most of my CPU. I found out that there was a quesed print job under Adobe PDF writer that was doing it. Canceled job no more CPU usage. Hope that help.   Matt B
This spoolsv.exe suddenly eat up my CPU at 99% and my computer become as slow as a snail. But this trick does work. Try cancel all print job in the Microsoft Office Document Image Writer. After the print jobs were terminated, all is back to normal.   ArcNemesis
It is a known Windows system file and a known virus. It can be either. There shouldn't be any arguing over it. If you are having problems, and it is taking too much memory, that is probably because it is a hoggish system file (cause it is). But if it is REALLY causing problems, make sure you do a quick scan for problems.   KasMage
I don't even have a printer hooked up to my computer and it is running this!   Mark
no problem in itself. can be infected, yes. if one cancel an already started print job, there can remain a bad print file, and the program will turn wild. check all printers and kill all jobs   Philippe
Was taking 100% of CPU. That was becasue 2 ghostscript files got stuck in the Microsoft Image Writer. Deleted these 2 files from the control panel, and we also deleted a printer that could not be located anymore. Problem was fixed.   Harish
This file is a windows file BUT viruses have been known to use the name so be careful only delete if your sure it is a virus   http://cianjg.bebo.com
this was because there was a print job waiting in Microsoft Document Image writer.   vergis thomas
If it exists anywhere outside the system32 folder it is very likely a virus.   Jaime
spoolsv.exe is a Windows system file. I could also be a trojan. If the print spooler is attempting to access te internet (use ZoneAlarm) then it's likely a trojan. Now I have to figure out how to get rid of it.   Ken Blakely
Spoolsv.exe misbehaves if you have a bad driver on your network trying to print. Use Start- Administrative Controls- Services to disable your Print Spooler, then go to C:\Windows\System32\spools\printer and delete everything. When you restart the service, everything should be back to normal.  
its a problem that comes many times when i want to print.it shows error n deletes all printers installed but when i restart computer it prints then displays the spool error again. Am fed up   charles
The legitimate version of spoolsv.exe is simply your print job spooler. It is a Windows component. That having been said, malicious programs / code can be named anything. As a rule of thumb, always keep your security software updated and running.   LocalHost
Go to the printers and remove all print jobs that did the trick as mentioned above   Dustin Thai
It's just Windows. You solve this prob by deleting all waiting print jobs or just install Linux :P   Julian
Not dangerous if inside the windows folder   nephisto2
Its to do with the printer spooling but my firewall (Zone Alarm Pro) pops up now and then saying its requesting access to the internet. A print spooler wanting net access? I'm blocking it every single time with no ill effects - next time will be a permanent block.   Zeb
followed advice of others and cleared my print queue. CPU time on spoolsv.exe went from 50+ down to 0. in most cases, this is probably not a virus...i think   jon
Today i've found a spoolsvc.exe file located on my windows/system32 folder. Well, that's a Trojan, just delete it. Do not confuse it with spoolsv.exe (a windows legitimate program)   Ad Astra
Yep print job waiting on image writer,, fixed it !  
When a document gets 'hung up' between the computer and the printer, it will nearly completely take over your CPU causing great slowness. Go to Control Panel, Printers, and clear waiting documents.   bob
It's on my pc as well, and it was taking up 99% of my processes, finally I took Ben's advice, and found a pending print job on my document writer (which I don't use), so I cancelled the job and my cpu usage was back down instantly! So NOT A VIRUS, JUST CLEAR YOUR PRINT JOBS ON UNUSED PRINTERS, OR ERASE ANY PRINTERS YOU DON'T USE!!!   Angelique
Windows Spooler Service   ken may
really annoying process, don't quite see the point in it. most printer programs have a spooler now anyway. WHAT IS THE POINT TO THIS PROCESS? just another one of those annoying windows freak processes with no useful purpose. thanks you all helped me lots with this process. does anyone know how to delete it?   James
Can be corrupt, But the reason why it has to connect to the net, is because sometimes you print pages from the net. So it has to access them. Go to control panel/admin./services and set print spooler to manual. after you stop the process.   FRED INSTEAD
Don't delete it! It's a part of windows that will handle the printer. It might use loads of memory if you have unprinted documents. Go to C:\WINDOWS\system32\spool\PRINTERS and delete all the documents if you are having problems with it. Problems with Spoolsv.exe, might be connected with the virus called Backdoor.Ciadoor.B Trojan, so have an updated anit-virus program.   Peter B
Okay, This is ridiculous. This is a place to post user opinions. The problem is, you can't say that it isn't a virus/trojan, and you can't say that it is. This is a valid windows process, but it isnt hard to build a virus with its process name as SPOOLSV.EXE . One way to Identify if its genuine, look at the Process Identifier (PID). If it matches the PID of the genuine Spoolsv.exe, then you are safe. With the downloading part, you can download it without you knowing it easily as an active x control, or just by visiting a site. But it doesnt matter if you Download it, only if you execute it.  
This is completly safe, when I first formated my hard drive and installed windows xp os on my computer, and a couple of drivers it was on the process list (and this was before I was connected to the internet so I am completly sure it's safe)   Brian
If Spoolsv.exe takes a lot of CPU usage. Go to Printers and Faxes and cancel any pending documents that may be at the MS Office Image Writer spool. That fixed the problem in my computer.   Bernardo
Here's another way to fix. Visit here http://torque.oncloud8.com/archives/000384.html This problem should fix immediately or if you keep it for long time, it gonna spoil your CPU   Anonymous
With my computer, anything Adobe seems to get the spooler off and running - Photoshop and Reader both cause me problems. Killing and restarting the print spooler service stops the problem until the next time I run an Adobe product.   Brian
If you have high CPU on spoolsv.exe that won't go away even after reboot, go to "Pinters and Faxes", click once "Microsoft Image Writer" just to highlight the icon. Left of the window under "Printer Task", select "See what's printing". If you see pending printing jobs, cancel all of them. spoolsv.exe will let go of your CPU. If you don't have a need for Microsoft Image Writer, just delete it.   Pinoy
Unhandeled print queue causes huge performance usage to the cpu. Note that, also cases when you have removed ur printer from your computer and the queue has been unprocessed, it will take take perfomance as long as there is that printter installed   -Z-
It automatically starts up as a windows process even though I have never installed a printer on my computer, and it appeared right after I accidentally opened a suspicious file from Limewire  
Mine was at 100% usage for about a week. I went to printer and faxes and right click on my networked printer and chancelled all the print jobs. My computer is back to normal.   Trunk
there were jobs waiting to print, 6 of them even though I did not know about them. then it wanted to print a picture that I scaned for a file only. it devoured my cpu to the tune of 98% so I deleted 5 of the six jobs. the 6th will not cancel. then I ended the process with windows task manager. and cpu was mine again.  
It keeps coming back after I delete it. I told Kapersky to quarantine it finally. That keeps it from coming back, but Kapersky MUST be running which is a pain since it's such a memory hog. :)   /)avid
MS exe part of OS. Check your print queues to all printers. Delete and you should be good to go.   Timothy M
This is not a Virus or a Trojan, just go to Control Panel, Administrative Tools, Services and stop the Print Spooler. Turn off the printer. Now go to C:\WINDOWS\system32\spool\PRINTERS and delete the files there. Once you have done this retstart the Printer spool service   RudyB
Lagged my computer out at first when I got a virus, and once it stopped, it constantly tried to access the Internet, which doesn't seem neccesary for a printer spooler.   Greg
It was hogging 50% cpu, I found 3 test pages waiting to be printed. they were there for a long time until I found the cpu hogging issue. Just delete the print jobs!   Taylor
When ever u start your windows it starts automatically and entire your CPU timing is grabbed. so to over come this problem u first stop this service from service manager and just delete this file that is "spoolsv.exe" from ur C:\windows\system32 directory and restart ur machine....  See also: Link   Vishal Tambolkar
I caused my spoolsv problem by trying to print an OpenOfficeWriter document on a printer attached to a different computer in my home network. The document never did print, but later I realized that the computer hosting the printer was _extremely_ slow and almost non-responsive. I finally fixed it this way. I did ctrl-alt-del to bring up Task Manager. (It took a long time, but eventually came up.) In Processes tab, I saw that 99% of CPU time was in spoolsv.exe. I ended spoolsv task and opened ControlPanel Printers&Faxes. I cancelled the document in MS Office Doc Image Writer. Solved!   Stanley Sokolow stanley
When you delete this file, all the printers you have installed desappear. Do u try ?   Leandro
This process is the windows spooler. I have noticed that a process prints a large amount of print jobs to a tcpip printer then spoolsv.exe uses excessive np memory. (Non-Paged) When this happens on a server it can take down the whole server and error ID 2019 "The server was unable to allocate from the system nonpaged pool because the pool was empty." appears in event viewer several times. Server may grind to a halt and disconnect any or all tcpip connections. Link below re this.  See also: Link   Andrew R

This is a print spooler. Do not delete it unless you want a bigger headache. It was clogging up the CPU on my computer. I simply went to the Control Panel, and clicked on the Printer and Faxes icon, and found that there were 10 large documents waiting to be printed on the Microsoft Image Writer. Just right-click and select Cancel Printing, and it will clear them.Turns out that someone had shared this resource on the network, and someone else, not knowing what printer they were supposed to print to, selected the Image Writer as their default, where their documents were left sitting ever since.   Brian

As everyone here has already said, spoolsv.exe is a windows process and can be infected by a trojan. The easiest method of temporarily stopping the CPU spikes should be to just say "Pause Printing" on your installed printers. If you don't have a printer and still have problems with spoolsv.exe, then it's worth a scan with your antivirus.   dhimiter

Its a PRINT SPOOLER. It went amuck when I tried to send a large printout to CutePDF. Open the "Printers and Faxes" window and you will likely see that there are documents that are wanting to be printed. Figure a way to get them out of the Queue and things go back to normal. Problem was NOT CutePDF, but rather the application that crashed while spewing garbage to the printer.   AimlessRolling

Windows System File for print spooling. Eats up CPU if there are jobs pending for the printer (especially Document Image Writer). Could potentially be corrupted by virus/worm etc and cause serious CPU activity. But in my case it was just documents queued for the Image Writer.   Dave Sugrue

Actually this prog play a role in finding virus, worm or whatever you would classified. However it is critical for the system so I keep it but I'd rather my window again and check out with spool printing (Thank you for this). You know it consumes 66% of my cpu and every time I start the windows I have to stop 'spoolvs.exe".   Wittya
it dont do anything but take up 1% of my CPU and i dont have a printer i only have 760mb of ram so i try to keep a lot of stuff like that closed as much as possible   _ko0LaiD_
Wow, I don't know why so many people fight. Obviously it is a windows file used to spool print jobs, but obviously it can also be manipulated by Malicious code, That is why some people are having stranger problems with it. I am sure the majority of people are able to fix it by removing whatever was queued to the printer/fax/Office Image Writer, but the chances of this many people not knowing what they are talking about when they say it is probably something Malicious, are very unlikely.   Falconman
It was a job in the queue for Microsoft Image. dont know why - I dont use it . As soon as I cleared, everything returned to normal. Thanks for the info I found here on this site   Franz
used ~20% of processing power constantly while printer was out of paper. Once printer was filled with paper and print job completed, this service stopped using my processing power and everything went back to normal.   Mike
The spoolsv.exe is simply a printer spoolers process it is used to stored data going to the printer. It is completly harmless. The only reason this process would try to access the internet is if you were printing a webpage. Do not delete it if you do you'll find your printer takes a lot longer to print. The below explain what the spooler does.  See also: Link   Steve

ain't critical for the system, but slows it down imensly by taking up more than 50% of cpu. quitting it using the task manager will allow you to get back to normal speed, but important system processes are still getting blocked. ( prevents dhc client, getting network adress )   bhead
basically this file only ever used any of my CPU when my printer was actually working on my computer. ok so this thing did actually cause my computer to slow down but only because my printer decided it didnt want to print. turns out there was a programme error within the software for my printer. as soon as i uninstalled my printer, 'spools' stopped using any CPU. so if you no longer need or use a printer, uninstall the software fully.   steph
I did as a couple of you suggested and checked old printer ques, whose printer is no longer present and there was one full of old files.   Dallas
Print spooler service. If it is using CPU cycles frequently, check the status of all installed printers to see if a document is trying to print, possibly on a printer that is disconnected. Delete all print jobs and CPU usage should drop back to 0   boxmonkey
Check your Microsoft Office Document Image Writer. There is likely a print job in the queue for this printer. This is the cause for the SPOOLSV.EXE to hog system resources. Delete the print job and you will be amazed.   ChuckDeisel
This may be dangerous sometimes, it was stopped by my processor's DEP(Data Execution Prevention) function yesterday for the first time but i found it in system32 so it is not dangerous. If u do not know enough, Don't mislead people.   geek_1
it is just a windows application. From time to time it like many other programs "hangs" and uses lots of memory. like what was posted up before, restart the spooler program and refresh the job/Document query window and that should clear up the problem. You don't have to scan it for a virus but it never hurts to be that cautious. As with any program it can be infected with a virus but more than likely it has "hung". It and several other progams periodically access the internet to check for updates. Most firewalls and internet security software pop up alerts when programs access the internet.   Kevin
Might hang if there's a faulty print driver. Just reset Print Spooler service (or disable it if you don't print)

Usually I use my computer for work related business. Some of those files cannot be save it. I realized a tricky way to save them through Microsoft Office Document Image Writer, the document become open with this program and later you can save it. When I read some of the comments I found one exposing conflicts with Microsoft Office Document Image Writer immediately I went to the Printer & Faxes folder and there it was several jobs pending in this folder. They were removed and the computer start working just fine, Seems for my perspective a conflict in the operative system and not a virus/worm.  
From what i have heard and read as can see that this is either a worm using the same name or its being exploited as i have had pop ups ever since this pop up one day and this isn't even hooked up to a priter....also just had two DoS attacks :S   J
Yes it is a microsoft file from your printer like most of you have said. Except there are trojans or spywares that can creat multiple copies or fake "spoolsv.exe" which continuely access your Internet for no apparent reason. Instead of deleting the program if your unsure if it is a virus or printing file from microsoft, simply rename the programs one at a time to see which is the virus and which is a regular microsoft file. You will see that one of the "spoolsv" copies is the correct file. I had 6 copies of the same file and my printer wasn't even plugged in or installed anymore.   geeks
spoolsv.exe is the spooling aplication that intercepts and takes over print tasks sent by other applications such as Microsoft Word. This is so the application that sent the print command is not occupied with the printing task and can contine with normal use.   OlieSmurf
This is the print spooler service. Even if you don't have any printers installed it will still show up as it is a system process.   Jay
this can either be a trojan or legitimate printer error that is eating up CPU. I just wen to Control Panel - Administrative Tools - Services - Pinter - Spool - Stop. Then go to Windows/system32/Spool/Printer and delete all the files. Now restart the service and the CPU should be fine again. If this did not work you either did something wrong or it really is a virus...   Tony Lam

If you go to your printer and faxes in the control panel it is more than likely you have some qued jobs you didnt realise, as soon as they are deleted it will cease usage of ur cpu   Joe
Buggy, but part of the os. A document stuck in queue can peg the cpu.  See also: Link   Widescreen
There was no jobs in print queue, but had a job in distiller & when I removed a job which was on acrobat distiller, CPU utilization was back to normal   Ayna
Not a virus, worm, trojan, ect its a simple process just like the rest. if it uses to much CPU time then maybe you have file waiting to be used in the back ground, it might be worth using ccleaner and selecting all of the options on and run this software it's free mind and see what happens after hitting reset if no joy still try hijack this and look 4 anonymous processes i had 1 with dodgy name somink like ACSHthr.exe never found a soloution on goolge or anywhere so tryed hijackthis and it worked good luck people so much 4 hackers and virus compilers world wide...LOOSERS..they need a life.l8rz  See also: Link   TekToniX
This application was necessary to run my HP printer and even get it recognised by my computer (i.e. without it, my printer did not appear in the printers list on control panel). Sure enough once I had the application running again Image writer showed up with a large file in it waiting to be printed (a remote download document). Now, this is my home computer. Why is there a remote download on it? Well, I went back through my network settings and beefed up my firewall settings and made double sure ALL print and file sharing tabs were off and there were no exceptions in my firewall settings.   EV
If spoolsv.exe is taking too much power on your processors, just take a look for pending job in your printer list. Normally it's because some documents are still hanging there. Check the Microsoft Office Document Image Writer and delete the pending job. Everything would be fine.   Jayadi Lukito
Yeah. This was happening since i shut my printer off and the file was stuck in there trying to print. I went into Task Mngr and i found that 100% of my CPU! so i canceled the .exe file and restarted the computer. I printed the document and worked fine completely!   Unknown

It spools files that you asked to print making printing faster   Ben
For Windows Server 2003 with CPU hog problem: If you don't have print jobs in the printers, just delete the two default printers that Windows Server 2003 installs. Solved the issue here.   Uncle Sam
spoolsv.exe is not a virus or worm, if u have a printer and u delete this process u will not be able to print and thats a fact i'm trained with microsoft and if ya'l think its harmfull then you are a idiot basicly the reason it maybe using 50% or more of your cpu is that u have printing tasks waiting maybe your pc has bin used for a network printer thers software out ther that will scan or do a reg scan that should help   badboy
Loads files to memory for later printing.   Zoe
I had a user's laptop that was running extremely slow. Ran ctrl alt del to launch the "tsk mgr" - "processes" - press on the CPU tab until you see a large number (95 - 99) to the left of that number is Image and user name, if that name is "System Idle Process" this is OK, but if it is "spoolsv.exe" delete it.   Truth
i have print service(spoolsv.exe)disabled and it seems there is another file with a same name ,probably a virus   pc.exe
Dystaxia was 100% correct. I deleted a print job that was pending and the cpu usage want from 50% to 2%.   unspecified
It is in fact the spool service for printing jobs. It was using 99% of my processor, and everything seemed to come to a halt, even after restarting my PC. Checked jobs waiting in print qeues, and there it was, 1 job waiting to be printed with the MS Image Printer. Deleted the print job, no more hassles.   Martin Blaauw
It just takes a lot of memory if there's something waiting to be printed. Otherwise, just go to the Task manager, Processes tab, and find it, end process. Look very closely though. Viruses may be renamed slightly differently. Ex : Spooisv   Liteprotoss
Just make sure you click on proper printer before hitting Enter or pressing continue, otherwise, yes it will slow down your computer and use up much cpu because it is trying to find the printer that is not installed or connected to your computer, doh` duhh... wow, some peeps are so jumpy over Proper Normal executive functions  See also: Link   shylev33

I don't have a printer, but tstill that flippin' thing takes up all my CPU time. Easy fix, just go to task manager and end process.  
actually when I open windows task manager, it only shows one application spoolsv.exe which always shows not responding... plz help me out to solve this.. this is happening for last few weeks... Sometimes it gives problem.. When I shut down my computer, I need to end spoolsv.exe by clicking end task or it will automatically get ended just before shutting down. I hope u understand my problem.. I am aware of computers bt not to that extend.. Plz help... thank u..   raman
Read carefully... spoolVS is malware, spoolSV is the windows spooler. If the Windows spooler is taking a lot of CPU, remove the Microsoft Office Document Image Writer printer. Also delete any files in C:\windows\system32\spool\printers (you may need to stop the print spooler service to do this)   Quasi
It belongs to MS. After reviewing this section, I went to my printers and learned that one of my old printers had 2 jobs waiting. After they were cancelled Spoolsv.exe was no longer using 50 percent of my resources. My thanks to the original person who offered the suggestion.   Joe
If you have Zone or Earlier Version so Norton, Spools can someimtes be overloaded for no apparent reason by them. Other times its random documents initiated by 'guest', and other time viruses. It was running 99& on both My PC's till i jsut used task manager to delete it. The first Tie i had to unistall Zone and install a differnt antivirus that didn't bloat up and take up a lot of space.   Justin
I had 100% cpu usage I thought it was a virus but it turned out I had printing jobs, soon as I deleted them cpu was back to normal   Shmoove
Tis file ysung CPU power 100% you can disable this spoolsv.exe for good and you can print much faster also. Go to control panel Administrative tools services... look for "print Spooler" right click the service and stop it or disable it   Michael
Yep, printer spooler. I opened the paper tray and lo and behold there's a sheet jammed. YAY fixed!   Electrodyne
spoolsv.exe is used for printing. i had this problem for a long time, it used 100% of my 256mb memory, my pc wasn't barely moving. I read this forum and deleted and reinstalled my badly installed printer drivers and now my system is running smooth again.   pinoy_ako
Sometimes spoolsv.exe colud be a virus if left unnoticed, the variant of that ceratian virus has the ability to hide its registry so be careful!!   Spectre
High CPU utilization problem solved after deleting all documents queued in Microsoft Image Writer as suggested. Not dangerous in my case, but I wonder if any virus out there piggy backs on it.   Wei-Chiang Lim
spoolsv.exe is the Microsoft print server. It was in the processes and I did have a print job waiting. I closed the process and it kept coming back until I deleted the print job. Then it stayed away. When I went to try and print again I was told I had to selct a printer and that then I was told the print spooler service is not running. Look to the other versions of this file such as spoolersrv.exe and similar ones. Investigation told me they were trojans etc. although I have no proof.   Gordon
spoolsv.exe is not a virus it self, but can be problematic because it is easily accesible to viruses trojans and worms.   DUH
If you have a network printer installed, but the protocol it uses is not enabled on any of your network interfaces, this also causes spoolsv.exe to run at 100%. enable the necessary protocols, restart and it should return to near-0% cpu usage.   Andy
I noticed one day it started to say end program spoolsvs.exe and then i wasnt able to multi task and its taking up 99% Cpu Usage   Nick

Just as the previous user. after I deleted the pending jobs the computer worked fine.   Falcon07
This is NOT a Virus, if it is taking over your RAM, i.e. using too much of it, check that there are no print jobs waiting and restart print spooler from the services.msc list   DBA - Matt
This popped up on my computer and tried to access the internet several times and I don't even have a printer!   John
Other than the Windows system process spoolsv.exe which is used to handle printing process and is important for the secure running of the computer any other spoolsv.exe process can be malicious and act as a backdoor.   Robin
Yes, it can be a virus. One way to tell is to right click on it and hit properties. There should be a VERSION tab on the real version. In my case, I had one copy in C:\WINDOWS and a second copy in C:\WINDOWS\SYSTEM32. The one NOT in the System32 directory was a worm.   Codo
I as aboove deleted all my work from the printer and up it comes wanting to contact a DNS best advice is let it and your comp and printer will work. but check where its from C:\WINDOWS\SYSTEM32 is fine NOWHERE ELSE THOUGH my comp ;s now fine  
I had spoolsv taking up 90% of my CPU and firewall access fault - I deleted and no errors   Sempi
FIXED IT IN 60 SECONDS- THANKS TO THE GREAT ADVICE ON THIS SITE! I had 100% CPU usage (97% was being used by this process. I took the advice I found here and went to Control Panel/Printers and checked all my printers for waiting jobs. There were 3 documents waiting to print on Microsoft Image Writer. I cancelled all print jobs and CPU usage immediately went back to normal.   Very Grateful
Codo is right i also had 2 copies of the file and the deleted the one not in system32, problem solved!! To all you saying it is not a problem, just because YOU didnt have the virus version doesnt make it harmless!!!   Virus
This file can be dangerous just like any file can be. In my case right now I've just been infected with a varient of an autorun viruz. I just traced it to spoolsv.exe putting an autorun.inf and a boot.com in a recycle folder on my D drive. Btw I have the Kaspersky antivirus engine on my computer and it will only pick up the files the worm drops not the worm itself. So I'm off now to debug and install some software. Maybe upload it to virus total to see if it's a new varient. Later   coz
my anti-virus (ESET NOD32) gives me messages saying that there is a threat in C:\Windows\System32\spoolsv.exe -something about "INF/Autorun virus". I have no idea what it may do to the computer, since i delete it right away. nothing related to printers (in my case).   Julia
first time this problem occurs - spoolsv.exe run 99%CPU for 20 mins then it cleanups to 0% -It may be windows 2000 glit- just let it runs it course I guess   Langong
It is a virus that causes the deletion of file-headers. That means you will loose a lot of files, although they still will occupy space on HDD. After that you can't access them or delete them so you will have to format your HDD. Only thing to do is to delete spoolsrv.   Ecaterina Andronescu
My printer was very slow and spoolsv.exe was running wild it took up 99 % of cpu so i disinstaled the printer and reinstaled it spoolsv.exe reapeared but wasn't runningbesides that I don't know much more about it   bigred

When spoolsv.exe takes 90% of cpu load on your system, 1) Stop the printer spooler service 2) Switch off the printer 3) Delete *.shd and *.spl 4) start the printer 5) start the printer spooler service   sandeep pawar
This is a spooler, followed the advice of about the third post and it was just a PDF program the user had a few prints going to. Got rid of those and boom her problems with a "virus" vanished. Check this first I think it'll sort 90% from what I've read above.   IT Support for ever
I had same problem -- spoolsv.exe was consuming 98% of CPU time. It took a long time because only a small % of CPU time was available for real work, but I finally brought up Printers & Scanners on Control Panel, saw that the Microsoft Office Document Image Writer had 4 print jobs waiting. I cancelled them. System reponse went back to normal and spoolsv.exe wasn't taking any CPU time now. It's fixed. The MS Office Doc Images were caused by an attempt to print on the LAN from another computer to a printer on the "damaged" computer, but the printing failed.   Stanley Sokolow
If you log in as the Admin of the PC, delete any jobs in the Document image writer and Delete the image writer, it should drop the CPU usage to about 5%   Tolu
Print spooler. Takes 40MB of my memory but 0% of my CPU. Codo hit the nail right on the head, check the version to see if it's Microsoft.   Ryan

When I know I won't be needing my HP Printer for any print jobs, I generally disable Print Spooler in Services so that it doesn't show up on TaskMngr--lately I'm backlogged with a lot of docs to print so I've decided to leave it on, but I've not experienced any high CPU or RAM usage with this file running in the background as others have--thankfully.

Spoolsv.exe is for printer system however encase you have more then 1 of these services running at same time and is using cpu or ram, It is highly advised that you scan the files for viruses and make sure there in the Windows/System 32 folder you should only need 1 but viruses seem to use this name as well obviously. :)   HAN
IF you don't have printer, then it's definitely a VIRUS  
If it is messing up your resources, simply disable it. but if you have a printer installed, you won't be able to print more than 1 document at the same time   Mustafa Sazak
it doesn't appear to be a problem until some minutes after you turn off the printer. Maybe there's an intermediate step to breaking the comp-printer connection? i'm testing right now with exiting the printer program in my tray. log off if you must, otherwise it comes back immediately   blahblah
not dangerous as far as my experience goes..... HOWEVER, i am having to end the process every time i want to run itunes....... its getting annoying and im not sure why spoolsv wont let itunes work....   robo167
There is a virus that masquerades as this process with a sightly different spelling I believe. I got it off my brothers computer using free avg.   mooseye
it was running at 98% cpu. CHECK PRINTERS AND FAXES FOR JOBS AS OTHERS HAVE STATED BEFORE TERMINATING PROGRAM. I Use a laptop, and i plug in and unplug the printer USB pretty often, so it left a job still "needing" to be printed.   Dusseldoffe
 
it is a vald windows file, used for printing jobs. disable or kill it, and it could do harm to your printer. it does eat up a lot of CPU, however.   bob

High absortion of CPU time. No Viruses detected. I'd like to know what the heck it is doing. There are no jobs pending in any print queue. And this compendium of complaints is not really all that helpful.   Reg
Spools is a virus free program for your system. If you have 60% + memory usage from it, you probably have printing qued OR you have the virus version of Spool. Many trojans disguise themselves as spool, but the real one doesnt take up that much memory space and it doesnt access the internet. Make sure to check your printer file and see if there are any qued prints before deciding that its a virus!!   Andy
Mine was stopping and restarting 10x per second. Causing the email inbox and other items to flash or refresh. I opened each printer and 2 refused to open. I reassigned the default printer away from one and to the other and the process was stopped. I was working on the idea that there was a print process corrupted and stuck in the logic circuits and looping. it was persistent across rebooting, but this fixed it. If you see this flashing, look at the task manager. The service will be appearing and disappearing over and over.   MrEdxoxo
It eats my CPU (up to 95%) IF the printer runs from startup and the icon sits in the system tray. Close that, problem solved. (My printer's a Konika Minolta, but worth a try with any printer, I guess!)   Penguin
I ran into an issue where one processor was pegged out. I read a lot of the comments here and nothing helped. I did not have any documents waiting to print. I did notice that it was adding a printer from the PC I was remoting in from. So if you have an issue and you are using remote desktop you need to check you options and not have it use the printers from your main PC you are remoting in from. This cleared up my issue with the processor and also with the speed of logging off.   Todd

this is a normal windows service. just go into coputer management/service and stop and start the print spooler service to clear it out.   billybob
After a succesfully finished printing job it keeps for himself too much RAM (23 MB), and my system slowed down (not because of the RAM - I've got 1 GB). Using Minimem I could get back the RAM (RAM for spoolsv.exe dropped to 22 KB), and the performance became normal again.   Lajos

Been having spoolsv.exe issues for a long time now, i used to just stop it in task manager but it would often restart itself. It was using 100% cpu and the computer was running very slow. A few people mentioned above that microsoft image writer may have a documnet qued so i checked this in the control panel- printers but image writer had no pending jobs nor did my epson printer, but there was a printer called "send to one" that had a job pending, i dont remember setting this up but it had something to do with an archiCAD file i was trying to print at one time. Cancelled it and runs perfect now   yeehaa

Go to task manager. End the process. Solve the problem. This is probably the problem, it should be an error with the process, it even prevents the user name in task manager to appear. Note : this maybe a critical process, do not delete unless it's a bogus and not found in system32.   Solution
Usually its a windows file...Check your printers for printjobs and cancel them...if that doesnt work use ProcessExplorer to see where its image path is...sometimes even where it is supposed to be windows/system32 iirc, it could STILL be a virus but prolly isnt   Tekno
go to Control Panel, Administrative Tools, Services and stop the Print Spooler. Turn off the printer. Now go to C:\WINDOWS\system32\spool\PRINTERS and delete the files there. Now turn your printer spooler back on and restart the service.   JRock2012

As many have said spoolsv.exe is used to manage print jobs. If in doubt check the properties of the file click on details and check the product and copy write name. These should all reference microsoft if not then its probably suspicious   rude boy mcdst mcitp
if it's the actual print spooler, it may have crashed. r-click on "my computer," choose manage, go to "services," select the print spooler and restart the service. if you're able to do that and it quits hogging your processor, then it was just a crashed spooler. if you're not able to do that, or it doesn't change the process-hogging nature of the beast, then it's likely the work mentioned above.   arjuna

it is not a virus but it will consume our cpu memory, this can be soled by deleting the printer waiting jobs or the image writer waiting jobs. once the waiting jobs are deleted then our cpu memory will not be used by spoolsv.exe   KuttiRajendiran

I run Windows Vista and kept on getting a box 'interactive services'. At the same time the computer would freeze. I found that yes there were print jobs still waiting in the queue. I went to control panel--administrative tools--print spooler and stopped the tasks. It's a niggly thing. Happens maybe when your printer runs out of ink or paper. You fix the printer but forget about the jobs still in the queue. Sure plugs up the CPU and slows the computer to a crawl. This worked for me and thanks to the many that suggested.   Geoff

It is a legitimate windows file because it is installed with windows thats true, but all the windows applications ask for access to internet when they are doing it and this one isnt so it looks like it is not so legit because it does send alot of informations about many things on your PC to some other partyes opening backdoors and its more like a spy than a legit process despite the fact that it is usefull for some rare things that u almoust never use. The positive things are the reason why this process is auto in the exceptions list in most of the AV programs. I would suggest block it or del.   Ilija

Just turn your printer off when ever you are not using it too keep hackers out. Im not certain if a hacker can use a remote call procedure to turn the printer on or not but keep itturned off just in case.   Dryson
for some reason i keep getting the pop-up sreen that says send or dont send and its about sppolsv.exe and i tried to print 1 thing and now everytime i put paper in my printer it keeps printing that same thing over and over again so have to keep paper out of my printer.

Takes whole CPU .. I hope If I can Fix this problem ,,   Ahmed Ghalab..
It's the Windows Print Spooler. People who don't use printers very often can turn it off by typing 'services.msc' in the Run box and looking for "print spooler", then press 'stop service'. You could of course quit the program in Task Manager but it may re-run itself seconds later. Not really bad to have on your computer unless out of curiousity, a file search is ran and turns up a different place than the system folder (sorry for the mac jargon, i mean C:\Windows and its subfolders) in case you will need to kill that file and recycle it.   Shin
after anew install of windows xp and SP2 it shows up in task manager, harmless and can be ignored.   Nekro
it does connect to inet it continues to listen on a port 49854, which means it can be conected to by the net, you could go to printer properties advanced and check print directly to printer, see if that helps. You may also want to block this port in firewall, i use comodo free it shows info on this service, keeps sending out udp packets and an ip address shows up now and then as well... meaning its reporting to someone.   billy the skid
It is infected by Trojan.Win32.Generic!BT on my computer VIPRE antivirus detected it. Trojan also infected sfc_os.dll and SBAMSvc.exe that belongs to Vipre... After cleaning Vipre wont start even after reinstall.   Vertumnus
DONT delete this file. It may act like a virus, but if u delete it then windows wont boot, just go to task manager - Performance - click the "Resource Monitor" tab at the bottom and a window will pop up where youll see spoolsv.exe, right click and end the process. It will start again next time you switch on   Atrax
Not a virus unless it is infected. This file is a service to print spooler for you enable to add printer on your computer.   Char
You may "Terminate" this process, but doing this may harm your PC.   Unknown
It is a legitimate windows file but it can be replaced with a extremely malicious application that ruin explorer, network managing and System Recovery. i got rid of it by formatting.   Henrique
this program some times effect the other programs   mark
It Clogs up my computer and destroys the memory   Bobby
I ended in Start Task Manager & then restarted spooler in component services.Thank You!!!!!!!!!!!   stubmenu
Delete contents of %WINDIR%/System32/spool/Printers and restart Printer Spooler service in Services.msc   lxk
I've never had a virus/malware that abused the spoolsv.exe file but from my experience with it, it's always been a file stuck in the queue of one of the printers. For a great tutorial on how to fix it, follow the link, it will really help you.  See also: Link   Time Traveler
In services.msc you need to go in properties and then change start-up time to disabled or manual, no automatic, and it will no start again.   Rekords
i think i got it with snagit...   Maxwell James Kelley
this is a virus the windows file is spoolsv.exe its situated at windows\system32 folder   dedan
It's a valid windows file (if not replaced by viruses). It works good most of the time, but sometimes it gets max of CPU percentage, seems to be a bug. I've just killed it using taskmanager and started it again, and it has started work properly.   Semplar

I cleared all the print jobs from all my installed printers and it cleared it up   justin
not only does it have to do with printing it also works along google chrome, i downloaded the software from this site and it locates it in the google chrome folder and also when i went to delete it, it tried deleting google chrome but first came up with a message saying google chrome is verisighned its also rated low on the security task manager list, it was the third from the bottom, doesn't seem to kill my cpu so i do not think it is a virus, if it seems to take your cpu you need to clear your printing jobs in administrative tools and also cant hurt to clear google chrome history and cache hold cntrl shift and delete at the same time, select the ones you want to clear (everything but the bottom two should be cleared every so often to keep google chrome running quick) and make sure its set to from the beginning of time at the top of that box... update, actually security task manager has it at the bottom but the risk meter is zero. im also currently checking all the files in the chrome location that the spoolsv is located on my computer through virus total, after about thirty minutes of scanning all the files in google chrome nothing is found to be a virus on virus total, also running a full scan with deep scan on avg found nothing.. now im not sure why mine isn't in the system location but i don't think this is a virus. if you would like find the file location on your computer, go to the website i included in the link box below and upload that file, this website will check 42 of the biggest antivirus software including avg, mcafee, pando, anti vir, comando, kaspersky, microsoft, super anti spyware and others.. the only one i see that i like that this doesn't have is malwarebyes but ive also scanned it with this and it doesn't detect anything.  See also: Link   colby green
I believe this is common with HP printers, but I am not entirely sure. This should be a safe file, however.   Tappy
In my case it was a legit file. The CPU was being consumed because my profile had 30+ network printers on it and each time I logged onto the server it was trying to connect and even install drivers for new printers on the profile. In Remote Desktop under Local Services uncheck Printers and make sure you only have the printers you need on your profile.   Rodador
My system boots slowly (takes nearly 5 minutes to boot). When I tried to check System activities through task manager, I found that Spoolsv.exe is continuously eating around 50% of CPU time. I am not sure if it is the reason for slow booting. I have not yet tried solutions given by lxk and Semplar   SN
I have this file in two different locations: Windows\winsxs\amd64_microsoft-windows-print and Windows\System 32. Properties show all other details mirror one another except location. When I originally searched for it, neither showed in results until I searched spool* and found them both.   KyFriedChick
Same as Dystaxia's situation, it turned out to be a print job stucked in the MS Image Writer. I went to printer control and deleted the job and the spoolsv.exe file stop running.   Hab
Spoolsv.exe is the printer service. HP Printers love to talk over SNMP, that's the reason for the big SNMP traffic load. I created a connection port on my computer for a printer using a static IP address. After the IP address had changed my computer started spamming my router with SNMP traffic. I deleted the connection port and the traffic was gone. I hope this can help you!   David
This is a standard windows process used to parse print/fax jobs. It is NOT dangerous unless the system is compromised by malware.   IcemanGJ
spoolsv.exe file is running without printing. As well as it takes 50% memory  
It is the printer spooler service, but there is a deadly rootkit virus that takes its place once run, and since the system re-starts this process automatically, it's a pain to get rid of the virus. But the original file is legit.  
Follow RMANN's direction. It was not a virus for me, WinXP. But it was 99% cpu.   Bart
it is system friendly file if no one mess with it and required to print the document in background, no need to worry.   Asif Ahmed
A printer spooling system that sometimes takes a strange amount of CPU and memory. If you don't printing anything, I suggest ending the process. However deleting the file itself can be extremely dangerous.   Grandmaster Quy
It depends on your printer. Turn printer off, turn it on ONLY when you wanna use it. And the problem is gone   Jackob
if you have an HP printer, this file is needed so you will be able to print. if you kill or delete, you cant print   ss
It is a service that loads a printing job into memory as an image if it isn't an image already, instead of text, so the printer doesn't have to understand fonts or decipher graphics, the solution on windows XP is to go to the notifications area, right click on the icon that looks like a printer, and click exit, that will clear the live cache that can be over 200mb for a 3 page document, I had a 200 page document in queue, it kept my windows XP with 3gb RAM at a halt until I exited the print job, however, don't try to end it by closing "spoolsv" from tskmgr, as it will cause a critical system failure, with a one minute warning until the computer reboots.   dreamwave development
