Okay, so I have a load of games that I have purchased myself and do not wish to let my brother play due to the content etc. (and the fact that he is spoiled and gets whatever he wants). Anyways, he is 10 and I am 17. Today I get home from work and he has somehow changed my password. The computer has 2 accounts: Mine with a password, and the other with no password. Both are admins. So all he had to do was log onto the other account and go into the User Accounts menu (via the control panel), remove my password and create a new one. Well in doing so I lost a sh*tload of encrypted files etc. I changed it back, but I know that he is just going to do it over and over until I change something. Any suggestions?
