Hi - I installed XP on my main system using nLite about 6 months ago. Every thing has worked great - I love nLite and I recomend it to friends to do similar things. Recently I discovered that I actually do need one thing that I trimmed out of my nLite install disc - Telephony support. Is there an easy way to just add that one part back? I'm guessing that I need to make a new nLite install disc with my old config, but with telephony added back, then do a repair install. Seems like a lot of hassle. I'm not sure if I still have the original config anymore either. How would doing that interact with all the security updates that I've applied since?
