Hello, Orion, welcome to the Seven Forums.
Your version of Windows 7 (RC build 7100) is only working six more weeks. March 1st (01-MAR-2010) it starts to shutdown automatically every second hour, and June 1st (01-JUN-2010) it stops working completely.
It would be better for you to buy and install retail version of Win7, because in couple of months your RC build 7100 is going to useless.
