I assume you already created a plugin directory for your install.bat, so all you need to add to the .inf is this: [SetupReg.AddReg] 0x1, "Setup", "CmdLine", "\Programs\example\install.bat" This is how nu2menu gets started normally. I did not test it with a batchfile yet, so you may need to use cmd.exe like this: [SetupReg.AddReg] 0x1, "Setup", "CmdLine", "cmd.exe /s \Programs\example\install.bat" If in doubt, copy the original nu2menu.inf over to your new directory and change it accordingly, it is small and pretty self explanatory. NOTE: You have to comment out the last line in the nu2menu.inf, or it will override your plugin: [SetupReg.AddReg] ; Install nu2menu.exe as shell ;0x1, "Setup", "CmdLine", "\Programs\Nu2Menu\nu2menu.exe" -- Pyron
