Install Python to C:\Python3 (Location is important)
Install Magic Wormhole, In a terminal as administrator type
pip install --upgrade magic-wormhole
That is all you need to do to have wormhole installed, but now to make it really useful, here are a few helper scripts and registry modifications that will allow you to send any file or folder from the file explorer and to be able to receive a file in any folder.
Create file C:\Python3\Scripts\wormhole-receive.bat
@echo off
cd %*
C:\Python3\Scripts\wormhole.exe receive
Create file C:\Python3\Scripts\wormhole-send.bat
@echo off
C:\Python3\Scripts\wormhole.exe send %*
