How can you assign a batch file to a special key on a keyboard?

I'm trying to use the special keys (play,pause,next,prev, internet) on my keyboard to open select batch files and im having trouble doing this with Windows or a 3rd party program

I understand you can change what media program is opened by going to default programs but that only lets you open media apps.

I tried assigning a keyboard shortcut to a batch file shortcut but that only lets you pick traditional keyboard shortcuts like Ctrl + Alt + O which is plausible but if I'm using a program that already has that key combo I think that program will intercept it like a bad pass

Any apps that can do this or how to do this without an app is greatly appreciated
