So my friend called me today and informed me that his wife had bought a computer from a pawnshop. They started it up in the shop and were logged in to an account but didn't really mess with it too much. So they get it home and discover that they can't get into the other accounts or delete them using the control panel. In control panel, when they attempt to go "User Accounts and Family Safety" they get a password prompt. All other user accounts are password protected. Obviously they should have passed on this computer or demanded a copy of Vista, but I'm trying to keep them from having to purchase one. Any help would be greatly appreciated.
