nLite is a tool for pre-installation Windows configuration and component removal at your choice. Optional bootable image ready for burning on media or testing in virtual machines. With nLite you will be able to have Windows installation which on install does not include, or even contain on media, the unwanted components.
Finally the XP SP3 was released so here is the final nLite version update as well. Just one important thing changed, SP3 Slipstream under Vista. It would reject your valid CD-Key. Not my doing but it is fixed anyway.
So in order to fix the XP SP3 CD-Key issues remake the Slipstreamed version from scratch with this nLite version.
