I'm having a problem with my laptop. I run Windows 7 Professional 64bit on it. An hour and a half ago I shut down my computer and Windows installed an update, but I stuck around because I wanted my computer off and I know that the computer restarts itself after installing an update. The computer restarted itself and configured the update, but when I chose to shut down the computer it actually restarted itself. I've tried shutting it down several times, but every time it starts right back up. I've run a virus scan, the Power troubleshooter, disabled automatic restart upon System failure, and searched Google and Windows help files for similar-sounding problems, all to no effect. My attempts to fix the issue so far represent the extent of my comfort in dealing with computer issues by myself, so I found this forum and decided to ask for some help. Thanks in advance.
