ahh, awesome ... i got it now. thanks for the help kalvin, and mc aines. i told my brother he could no longer get on without my permission, he tried getting on about 20 times and failed.. it wouldnt let him go anywhere without the password.

for those of you who want to do it:
shut down your computer.
turn it back on.
hit F2, (setup)
then go down to computer security.
click enter.
go to password.
enable password.
enter one you WILL NOT FORGET.
