This means that the user will be told to install a released version of Windows and their PC will shut down automatically every two hours. On June 1, 2010, if you are still on the Windows 7 RC, your license will expire and the non-genuine experience will be triggered. Your wallpaper will be removed and "This copy of Windows is not genuine" will be displayed in the lower right corner of your desktop, above the taskbar. Starting on February 15, 2010, Windows 7 RC should actually start giving daily prompts to remind you about the expiration, but just in case two weeks' notice isn't enough, we're letting you know a month in advance.
