My brother changed my computer admin account's password and I don't know it so I can only access now to limited account.> Is there way to reveal/change password? We are using Compusec Security Suite. I don't know the emergency password because he installed the windows and the stuff. Is there way to uninstall that Compusec? Or how I can access the admin account again? HELP PLEASE, I'll really appreciate it =) Or if I can't change/access admin password/account is there way to lock the whole computer using bios?
