"Thank you for participating in the Windows Vista Beta 2 Customer Preview Program (CPP). Your help is playing a critical role in improving the overall quality of what we believe is one of the most important OS advances in the history of PC computing. As a participant in the Beta 2 CPP, you will be able to download Windows Vista Release Candidate 1 (RC1) as soon as it becomes available.
In the mean time, we are inviting a limited number of CPP participants to help test a pre-RC1 build. Your timely feedback on this build will help us improve the quality of the final RC1 release that will be available to millions of customers in the coming weeks."
