thanks for clearing that up... i think -- i didn't pick a way to incorporate the reg file, but if i decide to auto run it in the ISO, should the comment remain (does nLite already set "reg edit 5"), or not, or does it even matter? while i'm at it, thanks to all of you for contributing to this project so that dummies like me can benefit. i can hardly wait to build my first "clean" windows ISO. i'm taking my time and trying to learn more about it so i can get it reasonably correct the first time around, because, wow, it's a lot of work if you want to build a complete, customized, ready-to-use install.
