Microsoft sends word describing the wind-down of public availability of the Windows 7 release candidate:

Still on the Windows 7 Beta? You need to move to the Release Candidate (RC) and fast. Starting July 1st, the Beta will start to reboot every 2 hours and expire August 1st.

Want to download the RC? The RC download program closes August 15th. After that, you won’t be able to get the download, but you can still install the RC and get a key if you need one. (To get a key, just go to the Downloads page and follow the instructions.)

If you’re using the Windows 7 Release Candidate, we hope you like what you see. Let us know -- go to http://input.microsoft.com and tell us what you think. You’ll be able to give feedback on various aspects of the operating system.
