Does Wpi have a Start /wait option for Nero? I want to use the Nircmd what Jasonkiller said but it only work when nircmd is extracted in Windows/System32. (btw.: It is working just GREAT when you stick to the "extract to windows/system32") OK, for Unattended disk you should have $OEM$\$$\System32\ folder on root of your CD disk. Anything you put into that folder get copied into Windows\System32 during the installation. So you can put nircmd.exe in $OEM$\$$\System32\ and it will be in the right place when you need it. Second posibility is that you make self-extracting archive wich contains nircmd.exe. This way you can call that .EXE in WPI before NERO commands, get nircmd.exe extracted in Windows\System32 and the rest is the same as before. I hope I make it more clear this time.
