Question : What happens when Windows7 expires ??
Answer : Practically nothing really. Here is what I found out by changing my bios dates to December 2009.
When windows starts, after the welcome screen, two dialog boxes come up (screenshots below) and u just have to click on "Ask me Later" in the first dialog and "OK" button in the next.
And after that everything, I mean EVERYTHING (including Aero), works just fine EXCEPT one small thing. U have to manually set the wallpaper everytime ur pc starts or u logoff and login.
So, be cool nothing bads gonna happen. I have checked everything.
