I know I’m preaching to the choir here. You’ve probably already upgraded to a full version of Windows 7. But if you haven’t or if you know someone who still hasn’t decided how they feel about Windows 7 and are still running the Release Candidate version, it’s time to act.
Starting tomorrow, March 1st, your Windows 7 RC operating system will begin shutting down every two hours. Your work will not be saved during the shutdown and the Windows 7 RC will fully expire on June 1, 2010.
After June 1st, your computer will continue shutting down every two hours and your files won’t be saved during shutdown. In addition, your wallpaper will change to a solid black background with a persistent message on your desktop. You’ll also get periodic notifications that Windows isn’t genuine. That means your PC will no longer be able to obtain optional updates or downloads requiring genuine Windows validation and you won’t be able to use Microsoft Security Essentials.
Don’t get caught doing this at the last minute and don’t spend 2 months being annoyed by multiple shutdowns each day. Install a official release version of Windows 7, or if you must, go back to what you had before. In either case, you’ll need to do a clean install to replace the RC. As with any clean installation, you’ll need to back up your data then reinstall your applications and restore the data.
