What I have done is stripped down my XP SP3 to where I want it. Added the key, dlls, wallpapers , games and so on with no addons, and burnt it to cd. I have it labeled SP3 basic. Then when I'm am ready, I can just add updates and the addons that I want from there, Saves me alot of time each time I need a newer copy. You may try that..works for me!
