i have 5 roommates. i have a desktop set up in the living room for everyone and their friends to use. it uses xp home. i have my own login account, and there is another login for everyone else. what i want to do is have it where when the user logs off, any changes they've made since they logged on is wiped out. any changes to the shell, registry, etc. any newly installed programs are wiped out as if they were never installed. can this be done, and how?
