Microsoft is sending out emails to users who have downloaded the Windows 7 Beta from the official download site. The emails contain information about the expiration date of the Windows 7 Beta and links to downloads of the release candidate.
The expiration date of Windows 7 Beta is August 1, 2009 but problems will start to occur on June 1, 2009 when the PC that the beta is running on will shut down every two hours
Thanks again for your help in testing the Windows 7 Beta.
We’re sending this mail to remind you that Windows 7 Release candidate is available and to make sure you plan ahead for when the Beta expires on August 1, 2009. On June 1, 2009, the PC you’re using to test the Beta will begin shutting down every two hours. Windows will send you a notice a couple of weeks in advance, and that’d be the ideal time to rebuild your test PC with a non-expired version of Windows, such as the RC or Windows Vista. This will be a clean installation, so be ready to reinstall your programs and data. (Learn more about installing Windows.)
The remaining part of the email contains information about the Windows 7 release candidate including download links but also the that a clean install is desired. Users who would prefer to update from beta to release candidate directly might want to check out our Windows Beta To RC Upgrade Instructions.
So, if you haven’t already done so, we highly recommend that you download and install the RC from one of the following sites today:
IT Pros/Microsoft Partners
IMPORTANT: If you are running Windows 7 Beta you’ll need to back up your data (preferably on an external device) and then do a clean install of the Windows 7 Release Candidate. After installing Windows 7, you will need to reinstall applications and restore your files. If you need help with the installation process, please see the Installation Instructions.
If you have questions or need help installing the RC, you can get help with your Windows 7 questions at http://social.technet.microsoft.com/Forums/en/category/w7itpro/
There’s another expiration date you need to keep in mind: Windows 7 RC will expire on June 1, 2010, and you’ll need to either upgrade to the final release of Windows 7 or a prior version of Windows before then. (We‘ll send you another reminder as this date approaches.)
Thanks again for your interest in Windows 7 and for your help in finishing this product!
