When Windows 7 Beta was released, the crush to get the download was amazing and took quite a toll on the servers. However, the Beta is about to expire. On July 1, Windows 7 Beta will start to restart every two hours and will expire on August 1.
If you wish to continue using Windows 7, it is time to move to the Windows 7 Release Candidate (RC). The RC will begin its shutdown process every two hours starting March 1, 2010. In the meantime, that will provide plenty of opportunities to experiment with Windows 7.
Feedback on your experiences with Windows 7 RC is invited at http://input.microsoft.com/.

May the wind sing to you and the sun rise in your heart...
