You're not still running Windows 7 Beta are you? Tsk tsk, better get your RC build before your system starts spontaneously shutting down every 2 hours. As Microsoft has warned repeatedly, Windows 7 Beta builds will begin bi-hourly shutdowns starting on July 1st in a bid to move you over to the latest release candidate. RC user will suffer the same treatment starting March 1st, 2010 on the way to a June 1st expiration -- well after the October 22nd launch date of Windows 7 to retail. This concludes this Engadget public service announcement, your regularly scheduled snarkiness will return in a moment.
