[quote=&quot;MattMan&quot;]Awesome, thanks for the info! I think i'm gonna make one for XP right now. I fix a lot of computers for people and a lot of the time I have to reinstall Windows for them and then install all the updates. After you get sp2 installed there are still about 100 updates left to go!! It can take a long time to do all this. This will save me a lot of time![/quote]

There's also something called 'slipstreaming' that's been around for years.  You slipstream all the windows updates into a new install CD.

If all you want to do is include the updates it might be the easier/faster way to go - I've never gotten into customizing windows installs other than including updates so I won't have to download them again.
