Vista - Vista MUIs

I'm trying to create a build with multiple languages. However I'm struggling
to get hold of the MUI downloads. (Not the LIPs). So far I have managed to
get hold of them by using Windows Update on an existing Vista build. However
this is a rather untidy method;

Selecting a required language
Choosing Install,
Waiting for the download to complete;
opening C:\Windows\SoftwareDistribution\Download\
The downloaded exe is placed here which when the installation begins unpacks
lp.cab
Quickly making a copy of lp.cab as cancelling the installation deletes this!


Is this the only way to get hold of the MUIs? There seems to be no way of
downloading these from www.microsof.com/downloads , also cant see them on
MSDN!
