The other day my laptop had a large install from WindowsUpdate. I assumed this was the service pack 1. After it download it took me to a screen that said "Installing Updates 1 of 3" after about 3 hours it finally finished, and I went ahead and powered my system down. A couple of days later I turned on the laptop, and it immediately restarted and tried to install again with the exact same thing. I left it alone, and after 5 hours it was still at 0%. After I restarted my computer, this never tried to install again, but now a lot of my Vista features wouldn't work. WindowsUpdate locks up, SystemRestore doesn't work, and OneCare says that it fails to open and that I should restart my computer. Is there anything I can do here, or am I going to have to reformat?
Also, if I reformat this pc, is there anything I need to do so that OneCare doesn't think I'm installing it on a new computer?
