I'm using SVCPACK method (T-13) to achieve this. I created appsDU.cmd and put it in SVCPACK folder. I added appsDU.cmd to SVCPACK.INF! appsDU.cmd runs my reg files I put in .\Install\Utils\ this way: start /wait REGEDIT /S %SystemDrive%\Install\Utils\tweaks1.reg start /wait REGEDIT /S %SystemDrive%\Install\Utils\tweaks2.reg start /wait REGEDIT /S %SystemDrive%\Install\Utils\tweaks3.reg and so on... You can use FOR command to get all *.reg files executed whatever their names are and how many of them are there. But using the simple approach above let's you run them in the order you want. Otherwise, use FOR command. NB: I'm not creating appsDU.cmd just for the sake of reg files. I, basically, use it to install my fav apps via SVCPACK. So, you know.
