Windows 7 mysteriously re-boots every two hours

If your copy of Win7 is mysteriously re-booting itself every two hours, and none of your changes are saved in the process, chances are very good that you’re running the Release Candidate.

It’s time to get real. Er, get the real version of Win7.

Microsoft’s Knowledge Base article 971767 has the details, but the bottom line is that two-hour re-boots start today, and on June 1, you’ll start booting to a black Windows wallpaper. It ain’t the end of the world, but if you haven’t saved your changes, the result could be, uh, startling.
