hi, as i have slept now and i can direct my thoughts where i want i think T-12min isn't so hard to change... The $OEM$-Folders are copied during textmode setup afaik, then it wouldn't be a problem to replace cmdlines.txt via a sfx-archive run from [DetachedProgram] @ T-39min from winnt.sif. That would allow to apply different registry-tweaks @T-12min, because HKCU-key's won't be applied @ T-9min. On my CD i apply all the hotfixes @ T-13min via svcpack.inf, @T-12min i install all apps and registry Tweaks and @T-9min i do some cleanup-stuff. And everything that can't be installed before i use RunOnceEx. And of course @ every stage i call XPlode to Install what i need. cya Killer Bee
