Re: Finding User "Footprint".
Programs that users install will always be housed in the Program Files or Program Files x86 folder, so the true footprint of each user won't be that obvious as all programs are dumped in the same heap, so to speak. However, if you login as the administrator and then go to the C:/Users/ folder, you can right click on the users named folder and see the properties to see how much that folder contains. Those folders, by the way, contain the My Documents/Downloads/Music/Videos folders so if the users are all average users, then they should be storing all their stuff in those folders.
Humans are the only creatures that won't live up to the their potential. Give everything your all. When you die, die on E.
So I ask you, what do you intend to do now?
