I'ts Windows 7 64bit.
yeah i took a look at it, but i confused my self a bit. Cus i have Steam on C: and the SteamLibrary on G: so all my games goes into one drive. does it matter witch drive i select? or do i have to make changes on both?
C: is a SSD and it is my system disk. And G: is my media disk, games, movies, pictures etc.
