No, my children have their own account with all full security enabled. I, as the admin, have password access that cannot be revealed to them even under extreme tickling.

I turn off the user account control for my login as it annoys the hell out of me. But leaving it on for the kids login means they cannot create or delete stuff by accident (or on purpose) or run any software not previously sanctioned by me. MwuhHAhAHHAH! The power, the power.......
