Answer #1
Yea man, windows is about 10 GB (BTW, you should be using windows 7, vista is terrible) and your user folder is only as big as all the crap you have in it. My user folder is about 50 GB =D
PS: There is a program -paroxysM^ linked that shows you the size of all your folders, I am trying to find it, will post back when I do.
