Just started using nLite to manage pre-installations of XP home and pro, and only have one issue with it, is there any way to insert "FactoryMode = YES" into the winnt.sif file before nLite makes the iso? Atm i just unpack the iso, and edit the file and burn. {edit} Btw, i noticed under "similar topics" that someone asked how to get XP setup to go strait into factory mode after install, well, this is how you do it, FactoryMode = YES in the winnt.sif and throw a sysprep folder in $OEM$\$1 folder, and make sure the sysprep tool is in it and you will then be able to use it to install and set system wide defaults that will persist after the OOBE. The sysprep folder will automatically get deleted in OOBE mode, this makes it a usefull place to hide all your special scripts etc that are used in configuring. If you get to the OOBE and you want to go back to factory, just hit ctrl-shft-f3, but don't try it on brand name pc installs, their scripts can do bad things if you un-seal them
