Microsoft:
Thank you for testing the Windows 7 Beta. You're playing an important role in helping deliver the best version of Windows yet. Now, we hope you'll join us for the next part of the Windows 7 journey, testing the Windows 7 Release Candidate (RC).

This is the really fun part of the testing process: you help by simply using the RC. When you do, your PC will automatically and anonymously send our engineers the information they need to validate the changes and fixes they made based on the Beta tests and your feedback.
