I am a PC user, running Window's Vista. I am not sure if I have my "window's updates" set up incorrectly or something, but I just had something unusual happen, and I was hoping that I could resolve it. I was on the internet when my computer closed programs and shut down to load three of three things entitled "configuring updates" it said, "do not turn off computer" and the home screen (when I log-in) was displayed. Is this normal? Did my computer download something? How do I check? Also, is this something I can control?... because I would prefer that I receive a warning next time my computer is going to log off involuntarily. Sorry this is such a green question, but I really know nothing about window's updates, or security, or whatever it is called now in Vista, so any tips would be really helpful.
