you're loving handicapped if you think that because windows 7 is newer that it's better
push comes to shove, you want that extra 512MB or 1GB of RAM that windows 7 uses with no background programs running when you're running higher-end programs or games
Just stop it.
If your computer is that stuff you need to worry about 512MB of ram being saved then there's problem 1.
If you're willing to downgrade to an older OS with (in comparison to W7) stuff memory management, stuff file management, stuff aesthetic appeal, terrible (if any) support for directx 11 and I believe openGL 5.0, and is just stuff and overobsessed overall, then there is your second problem.
Atop that if you're willing to take advice from a 15 year old script kiddie, there is problem 3.
get the forget.
