Wait until system boots up (will show login page again)

This is where the hacking begins!

Command prompt should now show (Black screen with text)

It should say something like:-    c:\WINDOWS\system32>

Type in:- net user

It should say something like:-    c:\WINDOWS\system32>net user (don't forget the space between net and user)

When finished type exit and then press enter. This removes the command prompt screen.

Continue as above....
