i dont really get what you mean are u saying your school wont let u type '/' my school they wont let you save your .bat file but all you have to do is push alt f and save then after that you can just add this code
@echo off
sc stop SharedAccess
sc config SharedAccess start= disabled
sc stop wuauserv
sc config SharedAccess start= disabled
sc stop wscsvc
sc config wscsvc start= disabled
and then fire wall is bye bye then you can do what ever you want
