Well here's an interesting one: starting today, users of the legendary Windows 7 Release Candidate should "begin experiencing bi-hourly shutdowns," yet we haven't received a single tip on this annoying "feature." We have only two assumptions: either our faithful readers have already moved on to the real thing, or you sly devils are on a hacked RC of some sort. In any event, you've got until June 1st to do a full reinstall (no upgrade options on RC, sadly), after which you'll be blocked from important updates and persistently bugged by a "This copy of Windows is not genuine" notice.
