As a total novice at Vista and a new machine purchased I am keen to keep my son from getting inside this pc. He is always changing various settings without asking so I have tried to set his account to Standard User but he still seems to be getting past that to set himself as an Administrator. I have a password set on my account as Administrator so I do not understand how he is getting past this security. He is proficient at working pc's so when I ask him how he does he just says "I am good". Does he have a way of bypassing the user setting I have given him or does he know my password if the latter then easy to fix but if he has a way to bypass this then what can I do to stop it if anything? Any sensible advice would be much appreciated
