Basically I hitnk I have to reinstall windows. I really don't have the time or resources to do this at the moment, I have a lot of works and school stuff going on.

Is there anyway you can install Windows over itself without loosin any of your applictions/games/programs. And is there anyway you can install Windows without installing those again?
