This is great software for slipstreaming your XP cd.
"nLite lets you choose which components to remove from your Windows
2000, XP or 2003 before installation. Removing unneeded components you
gain on your system speed and security. It supports removal of almost
any component and few services. You can make a bootable ISO with it and
even easy slipstream Service pack with a click of a button. Now added
easy cd-key implementation so you don't need to enter it during setup."
