The thing is I already have the latest version of both directx 9.0c and directx 11. Obviously directx 11 is not really going to help since my gpu does not support it. So even if I run a game, the game will not utilize directx 11 files. it will only use directx 9.0c files. So I need directx 10 which should be at least 100 MB. Also is it possible to extract dx10 from win vista DVD?
