This is just a heads up reminding you that on July 1st 2009 the Windows 7 Beta will shutdown every 2 hours and it will expire on August 1st 2009. So the best thing to do is download the Release Candidate if you want to continue to run Windows 7. However the downloads for the Release Candidate program will expire on August 15th 2009 so make sure you head over to the download page and download the RC.
And if you are already on the RC and like what you see or want to send us some feedback you can do so with this link. http://input.microsoft.com
Hope this helps you in evaluating Windows 7!
