Process name: Microsoft Desktop Window Manager
Product: Windows Vista/7
Company: Microsoft
File: dwm.exe
Security Rating:
One of the new features in Windows Vista/7 is the Desktop Window Manager (DWM). It responsible for the graphical effects such as live window previews and a glass-like frame around windows (Aero Glass), without draining your CPU.
A DWM-capable graphics card is required to enable the 3D effects, as well as Aero Glass.
(In older Windows Vista Beta versions, the DWM effects are controlled by the User Experience Session Management Service, via "uxss.exe".)
You can increase your computer's performance if you switch to Classic Mode (turn off Aero Glass and Animations), or reduce your screen resolution.
Note: The dwm.exe file is located in the folder C:\Windows\System32. In other cases, dwm.exe is a virus, spyware, trojan or worm! Check this with Security Task Manager.

| It can sometimes be heavy on CPU/Memory usage as it renders or runs out of resources. Ending it once will make it auto-restart itself - ending it again will make it permanently go and make the system use basic window management Max | |

| DWM uses a lot of memory and CPU usage in Vista however you do not have to end it in order for it to stop using memory. You can simply shut down a lot of the processes that the DWM file is using. Click on the start button, right click on computer and choose properties. Click on the Advanced System Settings link to the left; this will bring up the System properties window with the Advanced Tab chosen. On the Advanced Tab there is 3 boxed areas; Performance, User Profiles and Startup and Recovery. From the Performance boxed area click Settings. Uncheck any boxes on Visual Effects tab.

| Uses less than 20MB of memory, a drop in the bucket. A Pentium2 would bog when running this app, though a modern computer should run it like butter.. Calm down! Ram is cheap, 2GB is plenty for Vista unless your an idiot. I have 4 and don't use over half. - Though if you have a really cheap GPU/CPU setup this program may slow you down - Thats why cheapo computers are sold with Vista BASIC! A $20 GPU will run Vista AERO flawlessly, stop crying because you bought an IGP. I built a budget box and Vista runs beautifully, more refined than XP so long as you have proper drivers. | |

| Original dwm.exe is as said above desktop windows manager. But, same name is used by trojan/downloader Deewomz,. In my case this spyware is stealth downloaded in IE (the best is I am using FF, but have installed IE) some vietnamese page, nguyen or something. Most AV (kasp, MBAM,Super AS) will NOT detect it, but WSE wil detect it if it is spyware. In my case, file was in x:/windows/Desktop Manager/dwm.exe. Right now I am scaning full scan with WSE, then I will know is it removed or not. My OS is Win 7. I've noticed when running Ccleaner that my IE int temp folder is always about 20MB and I am not using IE at all. After that in CCleaner I could look how folder is bigger and bigger after every Analyze untill reach about 20MB. My main AV Kaspersky 2012 did not detect it at all. See also: Link Brajka | |

| I have rated it as dangerous because I found an infected version running on one of my PCs. Thanks to Christian Meinhold's comment, I did more searching. I found it was asking for permission to contact a strange IP address, didn't live in Windows/System32 folder and had a adult image for its icon. Checked with latest Norton Internet Security and it passed security, so I then did a system check with Norton Power Eraser and ONLY THEN did I get warnings that this particular version (a Trojan masquerading as dwm.exe) was unsafe. The important thing about this program is to check that it lives in the correct folder. Don't be fooled by its name, check thoroughly if you have doubts ;) coolstream | |
| dmw.exe*32 is a trojan (deewomz) designed to appear the same as dwm.exe - a legitimate windows aero file. In my case it pretended to be some sort of Firefox executable - I think that may vary from person to person however. If you end its process in windows task manager it just restarts. If you right click/open file location (leave the window open), then end the process, then delete the file from the open window, it seems to stop it. Just remember to scan you system thoroughly with a top malware scanner/virus checker, to eradicate any other viruses it might have loaded onto your system. Dave | |
