Hello, need help my brother play too much games in the computer and I want him to stop. So I decide to delete his account from my computer so that he cannot access my PC any more.... That what I thought but once I got home I found out that he can still play games in my computer. He was able to even make a new account to play games with. So my question is how can I prevent other people accessing my computer and also prevent them from creating the account. Please help a life of a person is at stake!!!
