I am having a similar problem. My computer died and when I turned it back on. It was doing Windows 7 updates. It took about a hour or so and when it was done it went to shutting down. It said on that for about 2 hours. Then I turned my computer off, and when it came back on. It said something like this "reverting window updates" and when that was finally done over several hours while I was asleep. It eventually went into shutting down. And when I woke up it was still saying Shutting Down. I let it go while I went to school, and when I got back. It still said Shutting Down. There is no way for me to get to the desktop. And I have tried to search for help, and it brought me to this site. So I was hoping someone could help me.
