So on my laptop i was the administrator, but then my brother removed me as it. He removed me and made himself administrator, so i can't install programs or change my own user account password!!! i am so pissed and i really want to remove him as administrator!! i tried going to control panel but then administrator password comes up!! please, please help, its my laptop so i should be allowed to hack the passwords on it or something!! i saved up a lot of money to buy it and now he's pretty much in control of it. Is there any way of knowing the password and logging into his administrator account and making myself the administrator without me changing HIS password, or is that impossible? I am really angry and im holding in all my anger, and it'd be all gone if i can make myself the administrator again.
Oh and when i go to control panel and try to install stuff and the administrator password comes up, it never use to be like that, no ones user came up, so maybe i wasn't administrator? but i wanna remove him as it and make myself be like that(with the password coming up and only me knowing it)is that possible? so he pretty much locked everything.
