I prefer to have a single installation of python, rather than having to 
remember to install packages for various pythons.
I choose the standard windows 64-bit install of python 3.8
But today when I tried to run a script ...

> Heidi@panter ~
> $ python3 x.py
> -bash: 
> /cygdrive/c/Users/Heidi/AppData/Local/Microsoft/WindowsApps/python3: 
> Permission denied

Surprise!

Investigating...

Hey, what is this? Windows reports that the owner of the binary is 
PANTER\Heidi, but /bin/ls reports Unknown+User?

I rebboted, unistalled python and installed the app store version of 
python instead, but nothing changed.

Any suggestions?
-Thanks
