I need Windows PE 2.1 to run a batch file automatically when loading has finished. I copied the file to: ProgramData\Microsoft\Windows\Start Menu\Programs\Startup in the Boot.wim file. Despite this the program will not run automatically after PE has finished loading. If the file is run manually it works ok. Is it possible to load a custom file by default?

any reason you can't call this script from startnet.cmd?

Thanks for the info used startnet.cmd and this force runs the program great.
