Hi,
Very simple guide:
First of all you have to know your username.
Klick START - Execute type CMD and enter.
net localgroup USERS /add -> enter
net localgroup INTERACTIVE /add -> enter
net localproup USERS "Username" /add -> enter
(e.g. net localgroup USERS Michael /add)
net localproup INTERACTIVE "Username" /add -> enter
Thats it.
It works on both.. Home and Pro.
If somebody can test this on an English XP Home..
I think it will work too.
Michael
