Hey guys, I don't know if you guys have found this list but I'm sharing it anyways, so that people who are just starting to play or have played around with Windows 7 would know.
I got the list from another forum. Here it is:
So far what the gurus have tested on windows 7 64/32bit

I will update the list as much as i can.
All contributions are welcome
