Ok - I know that I could write a batch file and slipstream a service pack (EX: XP SP2) to all of the affected windows distros (EX: Home/Pro Corp/Retail/OEM, etc.) that I have, but I'd like to have this functionality in nLite if it's not there already. 1) Is this currently possible in nLite 2) If not, what are the chances that something like a "distro manager" could be added in the future, so that I can manage all of the different windows versions that I work with regularly (I'm trying to put together a multi-boot DVD and I find myself applying XP SP2 8 times every time I restart the project). Any input? Thanks, Overkill
