Today Microsoft released a major app compatibility update for Windows 6.x systems that improves many apps & games, some of which I've seen some members complain about (notably Halo 2 for Windows 7). Although I've not had problems running these, or other, games with Win7 you guys should check out this list of apps/games included in the patch and give it a try if you're still having problems.
I'm not responsible if the patch eats your homework assignment or pr0n.
