"Internet Gateway Device Discovery and Control Client" component is installed automatically with an SP2 version of XP, the "UPnP User Interface" is not. Not sure how to sort it in an answer file either, soz.... Under "[Components]" in the answer file, add "OEAccess = Off", that should hide Outlook Express for you i think. Don't think you can avoid installing it as it's pretty much integrated into IE and everything else these days. Hope this helps.
