Welcome to Server2008 r2 Release Candidate (RC) testing. If you like trying out pre-release software, now’s your chance. You get to see what's coming, and we get to see if our changes and fixes from the Beta testing are working correctly.
How do you test the software? You put it on your PC, and then do what you'd normally do. Your PC will automatically and anonymously send our engineers the information they need to verify the fixes and changes they made based on the Server2008 r2 Beta tests.
You don't need to rush to get the RC. The RC will be available at least through July 2009 and we're not limiting the number of product keys, so you have plenty of time.
Watch the calendar. The RC will expire on June 1, 2010. Starting on March 1, 2010, your PC will begin shutting down every two hours. Windows will notify you two weeks before the bi-hourly shutdowns start. To avoid interruption, you’ll need to install a non-expired version of Windows before March 1, 2010. You’ll also need to install the programs and data that you want to use. (Learn more about installing Windows.)
