Windows Components install after initial installation

Hi,

Is there a command line I can use to install components, example Games, via
a script after the Vista initial install? We rolled out our platform without
Games, and we need to add them back. We don't want to visit all machines
manually and would prefer delivering an SMS package that would launch the
installation of the Games.

We used to do it with XP with a command like rundll32 install........
whatever is the code I don't remember.
