This is a fully working library that will allow the functionality of the python built in library winreg to also be available to users of python native to msys2, cygwin, and Windows Subsystem for Linux.
Just import wslwinreg instead of winreg and that's that's needed to allow your python script to access the windows registry.
This will only work if the host operating system is Windows, this library will always return errors if running in a native Linux (Not WSL) or MacOS machine.
