I have 2 administrator accounts on my Vista Computer but when I download something to one of the accounts,it automatically downloads to the other account as well.When I try to uninstall it on one account,it uninstalls on both account........help,what do i do?

Unplug your computer, put it on ebay, buy a mac. If you have money to burn, just check it out the window.

When you install programs, they get installed onto all accounts unless you tell it not to.
