Yes, you'll have to run it when windows starts. Dunno about launcher4kodi but you can put a shortcut in your startup folder, which is what I do.

Thanks, I will look into that

That script was chrome specific. I'll make sure the new one works with any browser

That would be fantastic! Can't thank you enough!

EDIT: in the meantime could you exit launcher4kodi and retry your media buttons with the keylogger? I just want to rule out any issues with launcher4kodi.

I quit Kodi, quit launcher4kodi, run your script and the results are the same (so nothing showing for play/pause etc.)
