The login screen comes up every time the computer boots and he doesn't have an account on my computer, so how is he able to bypass the login screen. I know he is because I can see the documents he is opening in the Recent Documents section.
I don't want him to get on because he uses it for surfing for online porn and he prints stuff wasting my ink. So I've been thinking of getting a lock for my room, but I was hoping there was a less expensive way to keep him off.
And I don't really want to confront him about this because I don't want to lose my temper and possibly fight him over this. This really pisses me off that he's doing this.
