Hello all, firstly sorry for this being my 1st post and already asking a question. I will post more and contribute to the community as I can since it has helped me much in the past. I also am sorry if this topic has been discussed already. I had already searched and browsed regarding task manager problems and found no posts that had to do with my specific problem.

My problem is when I press CTRL+ALT+DEL to open the task manager, a command prompt window comes up, completely blank, NO text in the command prompt window at all. The title in the window does say taskmgr so I know that it is opening the taskmgr executable.

I have copied a NEW taskmgr from my windows disk, and I have also run a CHKDSK /r, and a sfc /scannow with no success.

I have made full scans with Superantispyware, AVG antivirus free, and spyware terminator.
I have also had a successful run through of Combofix
All of the scans and combofix found only minor files, and cookies.
I have also verified the registry entries regarding task manager and verified the correct systemroot folders.

I wish I could give you a screenshot but the command prompt window flashes so quickly I cannot get a screen shot.

This has been going on for about 2 weeks so I would hate to system restore back to 3 weeks ago since I make many changes to my system daily.

Has anyone ever experienced this problem? If so, what can I do?!

I would suspect that something has corrupted your ability to access taskmgr.exe and would first suggest that you run SFC.EXE from the run dialog. There's more info on it here: http://www.bleepingcomputer.com/forums/t/43051/how-to-use-sfcexe-to-repair-system-files/

Finally got sfc.exe to work!

I had to copy the entire directory from the install disc to the hard drive, and change the location of the SourcePath and the location of ServicePack Path! I was originally only changing the location of the SourcePath, not the Service Pack as well.

It fixed it once I made the registry fixes and ran a full sfc /scannow
