Last week I came to work and one of my desktops had a black screen with just a mouse cursor. I wasn't able to do CTRL-ALT-DELETE but I could move my mouse and the keyboard lights were responsive. I rebooted, login to Windows, and got the same thing. Went into safe mode and had the curer, safe mode labels, and nothing else. Finally was able to do a system restore in command prompt and it worked again.
I was finally able to trace it down to a Windows Update that came out last week. I loaded each one one by one and when I loaded KB952004, it did the same thing again. Does anyone know why this update would cause this type of problem and can I do anything about it besides not loading the update.
