iOS push notifications on Windows

[Andrew at MidWest Coast Media]

The updated push notification lesson works great on macOS!

Can this be done from any other platform? I receive the following error when running the same codebase from a Windows standalone:
 'sh' is not recognized as an internal or external command,
operable program or batch file.
