How to fully uninstall Python from Windows?

[Winfried]

You just use the Windows Uninstaller.

Yes, I always uninstall apps through their installer, if available.

1. Removed Python 3.8.2 32-bits
   
2. Cleaned sys/user PATH of Python-related items
   
3. Deleted c:\Users\fred\AppData\Local\pip\ and c:\Users\fred\AppData\Roaming\Python\
   
4. Installed Python 3.8.3 in C:\Python38 per instructions
   
5. Checked sys/user PATH (USER: Nothing; SYS: Two items)
   
6. pip --version: pip 19.2.3 from c:\python38\lib\site-packages\pip (python 3.8)
   
7. Imported modules: pip install gpxpy: OK, but "WARNING: You are using pip version 19.2.3, however version 20.1.1 is available. You should consider upgrading via the 'python -m pip install --upgrade pip' command." → python -m pip install --upgrade pip: "Successfully installed pip-20.1.1"
   
8. Ran test script: No error.
   

Maybe it was because of the files the uninstaller left in c:\Users.

Thank you.
