I am a newbie when it comes to customising the XP installation but I found it interesting. I was amazed when I saw what nLite could do for me, although I faced some problems. I filled every field in the Unattended category but still my setup asked me for the language settings. I also wanted to slipstream WM10 into the setup CD but everyone was pointing me to this link, which does not work. Does anyone know another link that I can use to to down load WM10 slipstreamer?

i don't play around with slipstreaming and nlite, so i can't really advise you on your problems here.

nevertheless, there is one missing file (wm10 slipstreamer) you seem to be having trouble finding, and perhaps i can help with you that. i found another forum where the cmd script to do this is attached in the tutorial they are discussing to integrate windows xp with sp2 and slipstreaming all the hotfixes + integrating windows media player 10 as an added option. maybe the additional instructions there can also help with your other problem with language settings.

otherwise, you can just get the wmp10 slipstreamer to try it yourself.

it's an old thread (opened 2005), so instructions and the cmd script may not be up to date. and it would require you to register in their forum just to get the attachment. haven't done it myself, but i found your missing file there. hope you get to customize your XP setup to your liking.
