Windows owned File but look how is your place ... this place must was in the windows directory, when not it is hacked !   DoNe
As DoNe said..look at where it is: if it's in the windows directory, do NOT end the process or it'll restart your computer or something. . ..   Thom Chesshyre
This is the Windows shell (desktop, file browser, taskbar etc), closing it is not recommended. However, if the path is C:\Explorer.exe, it's a virus. (Due to lazy programming, Windows does not look in a specific path for this file. If it finds it here, it'll launch it instead of the real shell.)  See also: Link   Inuyasha
Part of the Windows Operating system. This program draws the taskbar and colorful user interface you see while using Windows. If you stop this process the taskbar will disappear.   Nathan

I think this is best explained as. This process is windows, at least so far as most basic users are concerned. This is the only file windows can't run without.

explorer.exe started to use 98% of my CPU. I found out that it was some downloaded mediafiles that caused it (films). I opened the task maneger and moved my mouse over the files and it went sky high. So I just deleted the whole folder without touching the file. It really worked.   Peter
The file is located in WINDOWS folder. If it is in system32 folder, it is a virus/trojan, for example TrojanSpy.Win32.SCKeyLog.20   LOL!!!!

There are two Shell in Windows one is CMD.exe and one is EXPLORER.exe. Windows uses HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon and under this key a string defined Shell includes this file. If you remove this file name and put CMD.exe and when u restart your computer next time Winlogon will open only Command Prompt and you will not see Start Menu   Nirmal Sharma
explorer.exe is in C:\Windows on most computers. One of my friends has his win dir as C:\Win2k though, so then this info would be TOTALLY wrong :P   Kramy
explorer.exe is a windows system file if found in the c:\windows folder. Found anywhere else it's malware, including the folders system & system32   TJS
This helped me find an explorer.exe file in an XP autopatch directory off the c drive. I renamed the file and my windows explorer shell stopped closing on me. Thanks, budsel83   budsel83
thats b.s. explorer.exe is no virus spyware its what your desktop and folders run under and its not the only one that your computer cant run with your computer cant run without win login.exe kernel32.exe rundll32.exe i know more then all of you and im only a 13 yr old computer genius   tomas berrum
Using System Task Manager it was a 64% risk and this was the text found in the file "Could not start Event Logger." And I keep getting pop ups to sites even though not surfing the net. Which are also mention in the text above, However it is in the system32 directory what do i do? and again using system Task manager only 1 explorer.exe shows up there is a Windows and Internet Explorer but only 1 Explorer.exe AND using the Windows Task Manager there are 2 an explorer.exe and an EXPLORER.EXE   Lastrider
It could be dangerous if its in C:\system\ or it hasn't got a This Computer icon. Change it into explorer.old if you're infected   D.
what to do if it IS in the WINDOWS folder (not system32 or something else) and cpu use is between 70-90 without a reason?! it doesnt stop eat my cpu when i open the taskmanager. there is really no reason (2600xp)   Janis
Can be used in totally undetectable background mode by Spectorsoft Spyware to report all of your computer activities to someone who has locally or remotely installed Spectorsoft Spyware on your computer on purpose at your PC or by email of an .exe file which causes the keylogging-system monitoring software to be installed without detection, not even in the Task Bar when it is operational. Spectorsoft installs about 20 hidden files and if any are detected they appear to be Windows\System files. SpyCops AntiSpyware can find a few of those.   jeffc333

the Task manager in my PC shows 2 explorer.exe files. one is in CAPS while other is in small letters. Certainly one of them is a spyware or a trojan.   Abhijit
ended the process as it took too much memory - DON'T DO THIS. now i've lost my start bar and all the icons on my desktop and have no idea of how to recover them.   Max
sometimes there could be wrong things going on this file. my explorer go nuts. i cant even copy and paste some big file because this causes my explorer cpu usage upto %100   ox_the_rider
Could the file be a virus even if it is placed in C//windows folder... what size should the explorer.exe be,,, mine is 981 kB (1 004 544 byte), thought first it had something to do with SP2 but it hasn't, not for me at least.   sMartin
I picked up some spyware and my computer would not boot up...it would crash everytime. SO, I made a boot disk and went into the windows folder. Lo and behold there was explorer.exe, only its create date was the time I had been on the web. So, I promptly deleted it. However, now windows will not work at all and I am starting to worry that I deleted the real explorer.exe.   Frustrated
I've an explorer.exe file that tries to access the internet once in a while. The file appears to orginate in system32, but when I checked its gone? Also, My AV app doesn't report anything, plus ther  
It is a important part of the Microsoft Windows Operating Environment.   Nate
explorer.exe is the default shell for windows. It IS NOT vital for explorer to be running to use Windows. And it is possible for explorer to chew up 98% percent CPU, if it starts behaving badly. If you open the task manager (CTRL+ALT+DEL), you can kill explorer, and use the task manager to start and stop programs. Since the shell that windows will start is located in a registry string, you could run any program as the shell (notepad, cmd, Quake III Arena, etc.).  See also: Link   spacemarine
something is up with explorer and its high cpu usage, i have seen it before, but can't figure out the problem.   Andrew

i want to thank peter for his input, I have managed to extracteverything but one bad avifile from my shared folder in emule, to a new folder. and deleted the old one. so now the flick and my problem with cpu being consumed, has gone. thanks, Peter.   marietta.
some films from emule makes explorer.exe use all the cpu available. it happens when i open the folder of incoming stuff from emule, and scroll down to the file in question. the minute it hits the screen cpu is skyrocketing. do i have to reinstall emule? i cant get rid of the films.   marietta

Dictates user desktop settings, taskbar settings, etc. Can either be in C:\Windows\System32 for Win2K or C:\Windows for XP. If you have an IDS, make sure explorer.exe is not included in any blocking or deny policy, unless it is not in any of the previously-mentioned directories. If an IDS blocks explorer.exe, it will wreak havoc on a user's desktop, especially for Windows XP. If an IT tech is not informed that the IDS might be causing the problem, he/she could be led to believe that the OS needs to be reinstalled. Just a warning.   calexander

Ok ppl! Explorer.exe is not a Virus, (unless one infected it). It is part of Windows. If you are unsure, jest replace it.   Some one who knows
Explorer is problably not a virus! lol... Even if its like 1000 kBs... Mine has about 44000kB of memoryusage when it runs and it doesnt hurt the speed of your computer very much, but you should get worried if the caps are wrong because that can meen that its a virus or some other shit like that...   Dadda
This file can be restarted if you click on File- Run in the task manager (WinXp Only) And type in explorer. So don't worry if it the screen goes blank.   Brad
Explorer.EXE uses up loads of ram..(thanks microsoft) it is located in C:\WINDOWS\Explorer.EXE for SP2 users, It is for the Shell or taskbar and desktop. dont stop it or youll have to restart .   Confuzeld

My explorer is constantly crashing, windows says that the program has to close due to a data excution prevention thing, in the error report this file is always included... explorer.exe.mdmp, in my task manager explorer is EXPLORER.exe, i have scanned for explorer and i have 3 explorers in he windows folder. one in /windows, 2 in windows/servicepacks/i386, 33 /windows/softwaredistrubution/download/6ca7b3a8efd5a9b6f87fff395a2eb989, i am thinking that there is a virus/trojan which is trying to use explorer o do something, but the DEP prevents it, i have scanned my system but i have found nohing   lucas
i got some kind of virus now that constantly starts up my system files, including files like Nail.exe, Explorer.exe and some other files.. i ran a whole bunch of virus, adware and spywarescanners over my computer, but it couldnt fix the problem.. anyone who knows more about this? --- and to Max: if u close down explorer.exe, just press ctrl-alt-del again. in the "file" menu you can start new processes. just make it start explorer.exe again and your desktop and start menu are back =)  
I open the task manager on windows XP and I see two explorer.exe. They are both the same no caps lock on one of them. But every few seconds, one of them uses all of my system resources (CPU). When I terminate one of them, nothing disapears. The name just comes back in the list and does the same thing as last time. I terminate it again, but it still comes back. What do I do? My computer freezes every 4 seconds for 1 second and it's driving me crazy!   TJ
Seems I have same problem as Peter- I think I got it d/l music, computer won't start up- it says there's an error and it has to close... Half of you say to delete the file, half of you say rename it or don't delete it at all!? So, If I delete it, and then the computer won't run-then what? Doesn't renaming it just give whoever implanted it there access to it still? HELP- can someone please put correct directions on this thread .. THANKS   Amanda

Usually fine, but potential for major trouble...Shoty, lazy (or intentionally lazy) coding on MS behalf has allowed certain groups to create (rather modify sort of) the coding to do almost anything. To my "knowledge" I am unaware of any person/group that have done this but hey never know. Ask MS about it, their response makes me laugh.   PGP
I agree with Dan Bishop. Explorer.exe is a file that is part of windows, but any hacker or virus could easily change the file to make it do dangerous things. My explorer.exe is making my computer run really slow and I think it is to do with bad .avi files as previous people have said here.   Patrick
Explorer.exe is the windows Shell (shows you the desktop, taskbar and start menu). Ending this process will make your desktop disappear. Use a Resource Hacker or Disassembler to rename the Start Button and other menu items, its real fun...   Raw
Do this check, find explorer.exe and if there is more than one result, right click it and click compatibilty or something, if you can change the settings delete the file. If you cannot change anything, keep the file you cannot modify.   Ben Smith
it is usualy a file needed by windows to run. BUT from past experiences it can be a virus, and because Windoes is very lazy it opnes the worm, locking up your computer.If it is not in the correct directory, youre in trouble lol   Ben Smith
if ended the screen will go black and the desktop will be useless but... if you're really in need of every chunk of mem to do a big task, you can use the task manager's "new task" to run any program with no cpu drainage   bleeding
2 explorer.exe files, both located in c:\windows. Cisco Security Agent detected this process trying to modify the Windows files opuc.dll, AeXNSBootstrapCTl.dll, wuweb.dll, and macromed\flash\flash.ocx.   RCODE
There should only be an explorer.exe in your C:\Windows folder. Others are not Windows system files. If you close the "real" explorer process you can start it again by typing "explorer" in "new process"   Slippers
this is the file has the capability to show the files present in the resourse in the graphical(folders and files) way. If we delete this file we cant access any files because desktop is demolished.   Dinesh
If it's in your C:\Windows file you have nothing to worry about. If it's elsewhere then it could be spayware. If you end it, you can restart it by going to C:\Windows and clicking on explorer.exe.   Danni Matzk
if you ended the Explorer process and you've lose the desktop, simply go to New Task - Run and type "explorer" and all will be well again

to reload explorer  
Heads Up. I found the file C:\WINNT\Explorer.EXE (Those Caps) on my machine. I checked it with Security Task Manager, and it was unable to load the file? Furthermore, I opened up an undelete program and looked at my WINNT directory, and found that the original file had been deleted a couple of days prior. (I have not done any updates that should have replaced it) I recoved the deleted file and did a binary compare. They have the same CRC check & size, but their content is quite different. I tried replacing the file with the deleted one, but the OS automatically recreates the file.   Aionios
its easy to remove hit ctrl+alt+delete then click processes then find svchost.exe there might be a few of em then end one of them that doesnt say localservice or network service or system and find the file and simply delte it make sure u dlete the real onethe realone usally has a little computericon by it but if u cant see it click tools/folder options/view then click view all file then uncheak view protected system files and for u idiott who think u kno computers and completly dumbi dont know what damage it does but i kno it does damge   waysmarter
ahmed, windows uses the prefetch directory to load some programs load faster or something, they are stored there and can't do anything much, but if theres a file not ending with .pf or .ini in there, it might be something else (I have a Layout.ini in there but it looks pretty safe) in short: leave the prefetch folder alone unless you find something out of the ordinary in there...   Sausage
I know that if you end it you can still you you comp but you will not be able to see you desktop, taskbar, etc. But I have a Q..I have to explorer.exe's running...one running at 10,000 K and the other at around 50 K, should I only have one? If so, which should I take off and what was it?   Ashley

Hey Max, If you still have Windows Task Manager open, click file, then new task, And type in explorer. I did the same thing you did. I found doing as I said above, gave me back my desktop and task bar.  
You can use task manager to stop it. If you find you stopped the wrong one, just click, File, New Task, and type explorer.exe. Your screen will flicker and the desktop will return. No Need To Restart   Ben Dover

This is a file in C:\windows. Its malfunctioning results in blank screen after startup. Don't know how to fix it. May be reinstalling the OS fixes this problem.   Abhi! Dave
This one is part of the GUI operating system, hence you really need it to continue running. If you shut it down, you will lose your "desktop" and may have to reboot. It is NOT Internet Explorer (iexplorer.exe).   DJ
It should be in \windows , not windows\system32 the latter is slyware.   Elrond
This is only a Windows shell file. It starts up the GUI (Graphic User Interface) i.e. the taskbar, start menu, and your desktop. There is no harm in it as long as it is in the proper folder (C:\Windows\explorer.exe for Windows XP; see Microsoft website for other versions of Windows). Do a Windows search (Start-Search) and search for explorer.exe. If more than one are found, contact a qualified computer professional before doing anything.   An XP Expert

Ok people, including 13 yr old computer geniuses who can't spell - the purpose of a file is determined both by what it is and it's location. If it's NOT in C:\Windows (in XP) or C:\Windows\System32 (in some other windows installs) it is very likely a virus. If it

If the process path is to C:\\Windows, then it is the process used by the Windows OS to display the interface (Desktop, Taskmanager, System Tray, etc.). When it is located somewhere else, such as C:\\windows\system32 (or system folder), then it is a potential virus or spyware process for sure! Use Hijackthis, Security Task Manager, with some startup managing programs.   PbLLoZeR
If you really want to screw with your co-workers, try exiting it through Windows Task Manager, and run all of your software without the evidence of the Start Menu. You can take it off their's too and see the fur fly. Kind of handy to end task and restart the bastard when things freeze.   BygNygga

When I do Ctrl+Alt+delte and go to process and delete this, my windows bar at the bottom disapears.   Colin
Au contraire, windows XP can run very well when you disable the explorer.exe. All you need to do then is to use the Windows Task Manager (Control+Alt+Del) and task switching as interface. I have yet to meet a program that DOESN't run on the background when I disable the explorer.exe. I can just pick the "Run" option from the task manager and choose whichever program; then that program works just like with explorer.exe enabled - just without it's additional memory load. Only thing you lose is the desktop, and the executive restarts easily when you run it from task manager.   Herra Tohtori

EXPLROR.exe is bad b/c it takes processing power away, mine was 50%. After I CTRL ALT DEL, I opened the File, run, browse, and searched for the file (in my case it was a DL'ed video) which I then deleted. Then , I looked for the explorer.exe file under my C:\WINDOWS\explorer.exe   Koreano67

Explorer.exe as in Executable file! is not a prob you either use it or you don't. It is a problem if its located in another directory then C:\ WINDOWS OPERATING DIRECTORY **C:\WINNT C:\WINDOWS or what have you). and if it is seing 99% cpu cycle then its not usally explorers fault. i went and playd avi files before and it maxd out as 100% on the explorer process.   Coty A.k.A XEARO

explore.exe was using on average 8% of my cpu constantly spiking to 16%. I shut it down using task manger then restarted it using the file, new task, explorer.exe and enter, It restarted went ballistic up to a 100% for a while then flatline at 0% where it should be. Saweeet!.   Johnny
It can be spoofed by changing the first two letters to another character set, then replaces the real file. Windows doesn't see the difference, but you can use the command shell, run the "dir" command, and the bogus file will have "?" where the letters of the filename are different,(example: ??plorer.exe)this is NOT explorer, even though it does the same job, plus a few extra that a hacker has included, follow the link for more info, can be used with (rundll, svchost, or any necessary windows file for malliscious purpose, Microsoft Security, there's an oxymoron for ya)  See also: Link   WarHippy

Like some other users here, I periodically find the file name has been changed to explorer.EXE (caps for extension) and appears in c:\Windows directory (XP). When I check the file properties, the date shows it has been modified recently and does not show the same dates as the latest explorer file from Microsoft; other info is same. I can't stop the process using task manager or other utilities. Never shows up as malware. Only if I manage to copy the original file back to the directory and delete the new one do things return to normal, but somehow it manages to return every couple of months.   TaxedByXP

it needs to die, it starts up about 40-50 internet explorers at once and makes my cpu usage allways at 100%, also earlier it crashed my computer and gave me some really bad pop-ups, my friend believes it could be something like aurora   penguin
i gotmyself 2 explorers. Explorer.EXE and explorer.exe both in Windows/ proving a pain.   Clarky

that when it is ended the start menu goes away so it has to be a windows nesecity

each time i close this everything on my desktop disappears and i can't use anything but the task manager but with that when i log out then back in everything is just fine. don't close this!   Phillip
renamed explorer.exe in system32 directory to .old and it quit hammering my firewall.  
Spyware Doctor keeps finding/deleting it. It keeps coming back but is invisible (show hidden turned on) under the system32 folder that SpyDoc says it is in?   deepcreek
Its quite a useful file to have if you run windows apparently   Big Brown Jobby
There is two kinds of this file there is one with captial letters i.e EXPLORER.EXE and there is one with small letters i.e explorer.exe, so i think one of them must be a spyware   A.A

all my processes are using alot of memory explorer.exe is one of the most memory hungry, when I use a memory optimizer the problem is solved temporarly from 200 free memory to 700 - 800mb I'm desperate now   Nicky
explorer is the file for displaying the info of windows onto your screen, it is a vital part of windows, but it can be easily modified to become really dangerous  
I had a problem with two explorer programs and decided to search out a way to get rid of the second one...nothing worked...so I checked add/remove programs on a whim and found something to do with "NSIS" and it wasn't supposed to be there...removed it and alls well...no second explorer killing my CPU and memory   Alan Harden

makes the internet work, but be carefull what your explore.   edgar
Follow Peters advice but only delete the file that uses all c.p.u. If computer running too slow to do this (ctrl+alt+del -explorer exe -end process -processes-type in explore exe) should now run with low c.p.u.   Steve
okay...if you are gettin' explorer.exe regularly gettin a 50% cpu reading in taskman what does that mean? 1st offc it tells me that you are running a duel-core processor. so now you can go to microsoft.com and look up fixes for 100%processor usage. if you have more than one explorer.exe in taskman is likely do to with a folder setting :open new window in a seperate process: not a problem.!!.Most of the time explorer.exe pinging out is due to downloaded moviesfrom p2p programs. do not download movies with the description in the filename.if you must try, shorten the file name   hittin1
It is accessing the internet with no doubts. Why would the file that runs your task bar and icons need to access the internet? When accessing some places on my hard disk it crashes and restarts. It is true backdoors can be placed in a file and the file keeps the same name and works however the size of the file will increase. There is no explorer.exe in the system32 folder only in the WINDOWS directory.   Cice
i wouldnt recommend closing it. it does not appear to be harmful. i stopped it from task mgr and everything on my desktop disappeared. after a restart everything was back. i would say it is essential to your computer operation   Jaces
It is the Windows User Interface. If you stop the process, you will lose your taskbar and desktop. Follow this steps to revert the thing back if explorer.exe crash: Press Ctrl+Alt+Del, choose File New Task..., then type explorer.exe. It should put back the things. If it's not, you might need to go to C:/WINDOWS/explorer.exe. If it's still not there, prepare to reinstall Windows.  
We found that explorer.exe use the ip port 1900, mean he go out to reach microsoft server. since when an internal program goes out from your system. even when you install a driver he send it to microsoft, this is why the security is so desastrous. Explorer or IE are the highest menace to the system security. in my case using Linux will be the wiser solution.   Antiss Neurotek
It is the start menu, taskbar, and desktop icons.  
Windows exploring process basicaly, shows files etc, about 20 programs run off it. Use 'Process Explorer'(search in google) and use it to find explorer.exe and find out what its doing, if your not running windows delete it.   Turnni1
This file Is The GUI (graphical user interface) which is your icons, start menu, etc, If the process is not from the "C:\windows" (9x, XP) Directory or "C:\winnt" (WinNT\Win2k) Then it is most likely a virus.

If it's a genuine part of Microsoft Windows and not a fake, I give it a rating of 5 (Dangerous). Otherwise, I would give it a 4 (Little Bit Dangerous) if it was a virus or trojan, etc. ----- Windows is dangerous, you should put the whole OS through a file shredder, destroys your computer more than any virus or trojan has ever achieved.  
Explorer.exe is really a part of windows, but there are sveral malicious programs that infect the file so that you don't even notice. I am having same problem with avi file like Peter (and it is for sure because of it!). I am wondering if header of that avi file is somehow changed so that infects explorer.exe, because file remains locked and drains resources!   mountaineer
I ended it and lost my taskbar and icons, but task manager was still running so i went to file new task, typed it in and got everything back.   L462
just CTRL-ALT-DELETE and restart the process if you think its running to high.   pz
this is a windows system file, but how to make it some think like that it doesnt take more resourses of PC, how to make it that it should work with minimum resources

This file can be a virus if it isnt named exactly like this "explorer.exe" int the directory C:\windows\ . If u=you close this file by accident simply open the task manager then go File New Task(Run) and then type "explorer_safe.exe" the go start run and type regedit ( if you arnt confident with the redgistry dont do this) then find the key at HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon and change it to whatever u named the copy of explorer.exe , in theis case explorer_safe.exe,,,,, hope that sorted everything out for you all  
this is explorer.exe, not iexplore.exe the internet browser  
Do NOT kill this process. It is needed. If not in the Windows directory, there could be somthing wrong. But if it is, leave it alone. Everyone else that says "OMG it killed my CPU GET RID OF IT" just wants you to mess up your computer (because they're jerks)   PyrisX
for all ur stupid ppl who think explorer.exe is only located in C:\WINDOWS, then ur an idiot. It can be located in C:\WINDOWS or C:\WINDOWS\system32. It's only a virus of there is random caps in it or if there is 2 of them or if a virus added/replaced its code with it. Ive made virus's b4 and u all prolly no nothing about explorer.exe -.-   Matt
my explorer.exe is fine. however reading comments above and from my past experiences, if the explorer.exe is not running from C:/windows/ AND OR if it takes up too much CPU its problably a virus or similar. Mine uses 48.1MB of memory but does not eat up CPU.

explorer.exe is the windows xp GUI (graphical user interface), meaning the taskbar, folders (e.g. my computer, my documents). If your taskbar and icons disappear open task manager, press run, type in explorer.exe and it should appear within 30 seconds. It is one of the most sought for when it comes to virus vulnaerability, and is a real pain in the ass to fix after its infected   Harb
In normal cases it is part of windows, if it takes more than 10% cpu then it is either a worm or it has a worm built into it   Phil
The discription on this page completely defines it, unless it is an otherwise fake explorer.exe it's absolutely safe, and quite necessary in my opinion. Although through various operating systems and computer disabling it is different, upon me ending it... my task bar and icons disappeared... not the most favorable thing to have happen.   DaDude9211
It's the Windows User Interface. If you have two running, one if them is 99.9% of the time a virus. To be sure you know what you've got, download the Security Task Manager and check it out.   Anon

The best advice to ensure you dont have a virus is take the drive out and slave it in another computer and scan it with nod32. If nothing comes up you dont have a virus or spyware... Nod32 catches all.   MediaManiac
It isnt dangerous i tried closing it and it closes basicly windows so its not dangerous but it has to be in the windows directory  
Controls the windows desktop etc. If you have TWO in the windows Task Manager, end one of them. If your icons, taskbar etc all disappear, DON't PANIC! End the other explorer.exe, then on Task Manager, click File New Task (Run...). Type in 'C:\WINDOWS\explorer.exe', and your desktop will appear. Simple!   Dean Fowler

original explorer.exe was replaced in my system folder with a trojan. i had to load in "safe mode with comand prompt" and delete the file and replace it with a copy from a machine with the exact same version of windows(xp home 2600 sp2). careful if you do this because if you have no knowledge of DOS you are skrewed and the only other way of manipulating files is to load explorer .exe which you cant modify if its in memory plus if its been infected you dont want it running. its incredibly rare for the actual explorer.exe to be infected normally they just make a copy with a slightly different na   kevan
As said its a key part of the Windows Gui. By stopping and restarting it you will pick up the latest changes to the the registry. This saves a little time compared to rebooting your PC.   Rob

This all started after trying to delete an AVI file. It said that the file was open elsewhere so I couldn't delete it. I opened its properties and found that an Unknown User had Full Rights to it, so I changed that and somehow found explorer.exe and opened it finding nothing. I then attempted to delete the program, but it wouldn't let me, then I applied the administrative rights and apparently deleted it. So now, I can log on but all i see is my cursor and a black screen. I cannot enter "explorer.exe" in task manager because apparently it doesn't exist. Nothing has helped yet......   saddler
explorer.exe was also using up 98% of my cpu & I keep getting pop ups saying I need to add spyware & malware protections. It's also added a shortcut to my desk top that I can not get rid of . I also deleted it from Task Manager, but just as quickly started it up again under new task on the applications tab. all you have to do is type in explorer.exe and your task bar & desk top reappear. But I now started getting pop ups :(   Sheila
This is 100% not dangerous, unless found outside system32. If you have 2 or more in your processes, one of them is probably malicious. explorer.exe is pretty much windows explorer. You end this, the entire GUI for Windows Explorer ends.   Rai

This file, yes, is basically THE Windows OS. Without it, you will, as stated above/below, not be able to see your desktop icons, nor your start bar. You can fix this by pressing CTRL+ALT+DEL, then select the Applications tab, then click on the New Task... button. Then, just type in explorer and press enter. A very effective trojan technique is to name the said program as explorer.exe . This is impossible to do, though, if the file is in the C:\Windows folder, since that is where the REAL Windows shell is. In any other location, it is, without a doubt, a trojan. Stop+Delete it!   Skylor Wold
Heres something interesting. If you end this process via Task Manager you lose the file system in Windows (Windows Explorer, Task Bar, etc) and then you have to restart to get the functions back. BUT, try this trick. Open Firefox before ending the explorer.exe process. Now end the process. All icons on the desktop disappear, and you lose all function to browse your hard drive etc as explained before. Now instead of restarting, download a file to your desktop via Firefox, right click in the Downloads tool box (Ctrl + J if its not already open) and select Open Containing Folder. Good luck :)   garrrr
Explorer.exe, if found in the windows folder is absolutly harmless and is essential. It is the gui shell, without it you can't navigate through windows at all. Now if it is in any other folder than windows\ then it is probably spyware/adware/trojan/bad. However, you can also get bad programs attached to the legit explorer.exe, but take care of those files, not explorer.exe.   Jarrod1937
While you're looking for fixes you can set the priority of explorer.exe to low in task manager - it will still run high when system is idle but will let others have a look in - you might need to set each iExplorer process to real time/high as these may default to low also. Not a fix but will allow you to research the answer....   Mike
Explorer.exe is the windows shell, it also provides your taskbar, icons, and file browsing windows. It is a critical piece of the Microsoft Windows Operating system and as such has more physical memory and CPU runtime dedicated to it. (this means that although TaskManager will show it taking up more of your CPU and RAM usage, it's not a bad thing, occasionally your system will become "bloated" with various add-ons and mal-ware, which will cause explorer.exe to use up more system resources.   P Klose

What is described above is wrong. I have never been able to shut down explorer.exe without shutting down the OS in any version of windows. The OS is tied to the running of explorer.exe inextricably. This has never mattered whether it's a new install without updates or driver installs or fully updated with drivers and windows updates. I'm stating this from personal experience in numerous OS installs with windows ME, 2000, & XP pro. Whether this may be true with older OSes I cannot say.   Frank Fuller
explorer.exe (spelt exactly like that) is found in C:\WINDOWS.  
explorer.exe is a windows application process that enables u to use windows OS interface. if u end this process u'll not b able to use ur desktop screen. but that can b recovered. open task manager by pressing CAD keys, click on file, new task and enter explorer u'll have ur desktop screen back. but its important to know the origin of the process if u've more than one process with the same name

it's the operating system, if you end it, you have to re-run it or restart your computer, if you want a custom interface, it's what you mod, if it is any other place than your windir (run, %windir%, if it's not in there) its probably a virus and should be treated as such   FBD
Absolutely harmless, it is a microsoft EXECUTIBLE which should be running to browse for files and start bar. But trojans and other malware can fake themselves to be named as explorer.exe so you should be checking about the memory usage of it. For example, I am using a WinXP Sp2 and it uses 22,245KBs of memory. If it is particularly high or low, you should be seeing it as a threat.   Musket
This is just a Windows Process. Do not delete it.If a data prevention thing prevents explorer.exe to work, and if your computer keeps crashing, follow my instructions:1. Before your computer bots, press F8.You should see a black screen with words. 2. Move your arrow buttons to make the options to last settings that work(or something like that) and click on enter. 3. Your computer should not crash now. Next, press CTRL-ALT-DELTE until you see the task manager. Click on new task and type in explorer.exe. 4. Everything should be back to normal. 5. Check for viruses. Hope this helps =D   tatsuya321

It MAY or MAY NOT be a virus. As a virus, it can easily disappear and reappear, replacing the real Microsoft OS explorer.exe. When it believes that it is discovered, it may hide and then reappear later. Don't be fooled by its location. If you think that yours might be infected, use every brand name virus scanner until your symptom disappears permanently. You may be able to identify it as a virus by the amount of CPU usage, but I am not 100% certain of that. If you kill it and your desktop disappears it is easy to restart. Just make sure that you are not restarting a virus.  See also: Link   Charles KnNell

The usual explorer.exe file is how you have the task bar, folders, etc. Contrary to popular belief, killing this process does NOT mean you have to restart your computer!

Well, dont remove this if it says "explorer.exe" in your task manager. It deletes the bar at the bottom of your screen. However, recently my computer obtained a virus and theres a new one called "Explorer.exe". I figured this one was the virus, because it hasn't been around long. So I terminated it, and nothing disappeared. When i restarted my pc, it was back though.

this file has 2 purposes, one is open your taskbar, the other one is run a copy of internet explorer 6 modifield to open folders instead of web pages.

Its the windows GUI and window manager, who really wants to type command line instructions when you can click on folders? all thanks to the explorer.exe executable ( to restart it, press Ctrl+R or Win+R and type "explorer.exe")   alex
Its the most important file in windows.   Dio Brando
If you are having problems with explorer.exe crashing when you access media files, disable thumbnails to fix this. What happens is xp tries to generate thumbnails of videos or pics by default. If you don't have the correct codecs or if xp can't find them, explorer.exe will go crazy. So just disable thumbnails to prevent this from happening.   MK

On XP, experienced a problem where explorer.exe would randomly freeze my computer and start consuming 50% of the CPU cycles under Task Manager Processes. It turned out that Client for Netware was somehow installed as a service for the network card. Stopping the service did not solve the problem. I had to completely uninstall it. Another peculiar symptom of this Client for Netware service was that when it wasn't causing explorer.exe to freeze, it would cause a 10 to 12 second delay upon the first attempt to open a mapped network drive. This would repeat if the drive was idle for 10 min.   leukram
It only takes about 8% on my computer.Do not kill this prosess or you have to either open it again or restart your computer.deleting it will give you the BSOD or your computer will try to keep opening it when it can't(it's probly gonna loop)   nerd
It is your desktop, file browser, and your task bar. If you close it, you can just go to the "Applications" tab on the Task Manager and click on the button labeled "New Task" and start it up through that process provided you know where to look for it in your files.   StuntPenguin91
explorer.exe is a shell for windows and its file location is c:/windows, if its location is c:\explorer.exe then it is a virus, to remove this go to safe mode and manually delete this file from c:\explorer.exe   Kulvinder Singh
If you terminate explorer.exe open Task Manager and click on New Task, then enter C: and explorer.exe is started again.   Rincux2

"explorer.exe" (YES, it must be in all lower case) is the base process of Windows. This core program allows you to navigate though you computer with whats called a GUI (Graphical User Interface). If for some reason you END this important process through the Task Manager, restoring your desktop is fairly simple. First, simultaneously press CTRL+ALT+DELETE, the task manager will appear. Second, at the top left corner, click "File", then "New Task...(RUN)". Finally, type "explorer.exe" [all in lower case] and press ENTER. Give your computer 30 seconds to 2 minutes to start Window's Explorer.   AlphaWolf
Is the shell of all windows operating systems after Windows 95, in other words: it displays the ui (taskbar, desktop icons, start-button,) of Windows, if it uses much CPU see here:  See also: Link   the anonym one
explorer.exe is the desktop and startbar. You can run windows fine without it, but it is easier to use then the command prompt/task manager. If not in the C:\WINDOWS folder, may be a virus.   kidfrommars
This is a very important system file, don't be fooled and remove it.. I myself done it once unintentionally.. And then had no way to start my windows but to format and do a complete fresh install of Windows 7!!!   Fuad
This file should only be located in c:\windows in W7. If you find a copy in system don't delete it however. Make sure to check hklm- software- Microsoft- Windows NT- Current Version- winlogin- Shell It should read: explorer.exe if it has a long entry just delete the key and replace it with "explorer.exe". Make sure to delete the entry it is pointing to as well.   Matt
the "explorer.exe" is a file that inject when startup. It actives taskbar and icons on desktop. So don't delete! If explorer.exe is on other folders (Default is C:/WINDOWS) It's an malware You need to install antivirus, if you have take an full scan!  See also: Link   VaLo
it is a windows component and it's location is in the %systemroot%   maino
I search explorer.exe and found 3 same name files. From the properties, all come from Microsoft. One in C:\Windows, the other two in C:\Windows\System32\dllcache and C:\Windows\SoftwareDistribution\Download\....\backup. All same file size, i.e. 1,008 kb. Scan them with various AV and Anti Malware programs and result: NO VIRUS, MALWARE, TROJANS, WORMS or other s**t! Conclusion: this is a legit file, not virus.   Jack
explorer.exe is responsible for windows gui. It is not necessary to explore windows but it is the most easy process to explore in windows. Without it you can also explore the whole windows just by typing address of folder u want to explore in task manager then all the files in it are listed in drop down menu of task manager.  See also: Link   Sailesh kondraganti
go back to "applications TAB" press "new task" enter - "explorer.exe"  
explorer.exe is an executable file. It is not harmful but it is essential for the windows startup menu and other GUI components on dekstop. It does not get started when other files in windows folder gets corrupted due to malwares. Easy way is to press ctrl+alt+del which opens up task manager. Select new and type explorer.exe on click on ok. By doing this the problem can be resolved for temporary usage only.   Sudip Kumar Jana
This is always safe if it is located in .../Windows. If you have ever tried to end this in the task manager, you will find you lose important stuff like the start menu (to fix this, just start it as a task again) explorer.exe is very important   Phillip

Somebody said that he/she has 3 explorers. Please read the directories very carefully and they are just updates   Anonymous
Its the host process for all windows!   Max
Never kill or end the "explorer.exe" process in windows. Because after that you cannot recover the task bar and Desktop icons and you will be screwd. Fortunately, I had a KVM console attached to my server and had to reboot the server to retrieve my desktop :-)   katalina
I went to task manager and saw this file was using almost 90,000 K of memory, did a google search and ended up here. I did a "search" on my computer and 5 files, 4 were similar to each other and last modified in 2008. ONE was modified on 4/1/2013 at 3:53 pm. That's really close to the time I lost access to the internet for 2 days! I was on the phone with Internet provider for 1 hour Monday evening and 45 minutes Tues. morning, they couldn't figure it out, so sent a tech. When he got here this morning it was working fine. Weird. Oh, also, as I was running a search for files containing explorer.exe the memory usage kept going down. It's now at 8,840K.   Tami
Just a microsoft process. Killing it is fine, you just have to re-launch it by starting new task "explorer.exe". Re-launching it will reload your taskbar.   B
It's ESSENTIAL to showing the task bar, and is included in the installation package of every Windows OS I know of (Windows XP, Vista, and 7).   AlekTheNerd

It's rather irritating when trying to open Windows Explorer and I'm told I don't have permission because of explorer.exe   Austin
Strange, When I log off (or shutdown) the computer, there is a non-responding that says "End Program: explorer.exe" something is very suspicious.   experienced_computer
