for the first time(it may have been there before but i never spotted it) today i saw in task manager on windows 8 a file called dwm.exe running under the details tab. this task was being executed by a username i have never heard of before "DWM-1" under the username column(all other processes either execute as "my username",  "SYSTEM", "LOCAL SERVICE" or "NETWORK SERVICE" )and the file located in C:\Windows\System32 with a size of 115 KB or so. i tried to go into the windows folder and scan this file with MBAM and it did so except MBAM gave a log registering to had taken 7 seconds to scan zero files, scanning with avg shows nothing. i suppose i'm a bit paranoid but has anyone else seen dwm.exe on windows 8 running under a weird username like that? and one other weird thing, when one tries to terminate this process with right click-->end task in the details tab of task manager the screen flashes black momentarily then comes back to show the process is still running.

thanks

it's not mentioned under services and it runs from a different user (today it is "DWM-3") that me or the usual SYSTEM,LOCAL SERVICE and NETWORK SERVICE. what's more i'm on windows 8, most things talk of it being on vista and windows 7.

 DWM.EXE is the Desktop Windows Manager.  It's part of Windows.  Leave it alone if you don't want to create problems for yourself.


Everyone with a computer should back his system up to an external hard drive regularly.  :thumbsup:

it's just really weird that it's running under another username.

 Computers and my wife often do things I'm hard pressed to explain.  I found today's paper in my toolbox.  If I hadn't happened to go in that toolbox, I'd never have know where the paper was.   :bounce:

Desktop Window Manager (dwm.exe) is a valid process that should be located in \Windows\System32.  DWM-1 is new system user in Windows 8 that is only used for the dwm.exe process.  The service will automatically restart itself if you end it, which is why it keeps coming back.  To answer your question, yes I get the exact behavior you do on a Windows 8 machine.  It's normal, don't be paranoid . :)
