I was just browsing around on the internet and all of a sudden my computer started to shut down and start updating. It restarted fine. There was no warning saying it was going to do this and none of my Windows alerts are turned off. I am running Windows 7. Anyone know why this would've happened? Nothing seems to be out of place or anything, but it did annoy me by not telling me it was even downloading the updates and by restarting on me without asking.
