Welcome to Windrivers janset... I am sure Guts will also add to this,
but to Run a program for command line, you need to have the command line window open.

In both XP and Vista, the programme you need to run is called cmd.exe
In Vista there are two types... if you just type in the search box, it will come up with cmd.exe, but it won't be running as administrator, which you need to do.

To get the administrator version, click the round windows button, go to accessories and you will see the cmd entry - RIGHT click on that and select runas Administrator. You will get a black box up, type your commands in there.
