The batch file is utilized by PinballX when accessing the settings.exe to launch PinballX during the Windows setup process. Its function is to copy the batch file to the user's 'run' explorer.
I have personally developed a custom batch file that executes upon Windows logon, without employing or substituting the shell.
There is no necessity to execute PinballX with administrative privileges.
All operations can be performed as a standard user.
Furthermore, I find the usage of JoyToKey undesirable, particularly considering that all the features I require can be accessed using a joystick.
