I have a friends computer running windows 7 that comes up with "windows desktop manager stopped working" each time the computer is started. Another issue, which could be related is when you attempt to open a photo it says the .dll file for the program to view photos is gone(can't remember the exact error and t he computer isn't in front of me right this moment).
I did the following after Google'ing the issue with no luck on fixing the issue...
I ran a few different virus scans to make sure it wasn't infected, which they all came back clean.
I ran CCleaner to clean all the temp files along with running the registry fixer that it has built in.
I have the video card to the most up to date driver
Bios is also up to date.
I booted into safe mode to see if the photos would be view able in there and they were not. Came up with same error as in normal mode.
I turned off DWM.exe from starting with startup.
I attempted to replace DWM.exe with a clean version.
I ran sfc /scannow. It said it found errors but could not fix them. I looked through the CBS log that was generated from the scan, but wasn't too sure what to look for on it.
I also ran the windows 7 start up repair from the disc which didn't solve the issue.
Last few things I tested/noticed today:
I went through MSConfig and set the computer up for "Clean Boot" and it still started with the error. That was with all non microsoft services and startups disabled.
I removed the video card(GTX560) and booted using the onboard video and the error didn't come up. So it has something to do with the video card/drivers
. Is it possible the video card itself has gone bad but just to the point of throwing that error each time?
