Not even sure this is the right forum, but I have been looking for a way to take an existing XP Pro system and adding several programs to it using a slipstream-type program. What I wanted this for was adding several pieces of software to a classroom full of computers. All have XP Pro. BTW, some of the programs are freeware and some are commercial. Also, I am new to nLite and just found that and am happy with it so far.
