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.
But if you are running the Windows 7 Beta then get ready for bi-hourly shutdowns to begin on July 1, 2009, and then the eventual expiration of the Windows 7 Beta on August 1st, 2009
