YOu seem to like to speak to yourself You ask a lot of things and not very clearly, That why i Think no one reply to you. I will try to answer some of your query. 1 Can a bootable ISO made & saved by Nlite be manipulated again ? Yes for removing, No for adding. 2 Is an Nlite made bootable ISO, with all the slip streaming, as good as a fresh install?? You can do a fresh install with nlite 3. Whats the extreme slip straming that any one has performed using Nlite.........btw which works too lol. Slipstreaming is not about removing thing but the action to integrate service pack or KB in a xp build. 4. Nlite shouldnt be used with antivirus, antispywares installed & active? It depend on you level of knowledge, I dont use any active antivirus or spyware. 5. Can one extract the OS from the recovery dvds? This method is hard, you shoud get a real cd of xp as a base. The rest of you question were not clear to me.
