How to fully uninstall Python from Windows?

[Winfried]

Hello,

For some unknown reason (updating Pip?), I've been getting this warning when using Pip:

c:\>pip3 install mymodule
WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip. Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue. To avoid this problem you can invoke Python with '-m pip' instead of running pip directly. Defaulting to user installation because normal site-packages is not writeable

Uninstalling+reinstalling Python didn't solve it.

What is the procedure to remove Python entirely from Windows, so I can reinstall and be done with it?

Thank you.

You just use the Windows Uninstaller.
Then look at Python 3.8 (3.6-3.7) and pip installation under Windows.

For fixing error you have this may work.

python -m pip install --upgrade --force-reinstall pip

But if want a new install follow link,and no need to use pip3.
Test with Python -V and pip -V after install,shall work from anywhere in cmd.

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.

6. pip --version: pip 19.2.3 from c:\python38\lib\site-packages\pip (python 3.8)

Okay.

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"

This is a normal message,just to remind you to upgrade pip.
I guess you have done this?

python -m pip install --upgrade pip

Test pip -V it should now show version 20.1.1.

So is all okay now dos also python -V work?
Example:

C:\python -V
Python 3.8.2

C:\pip -V
pip 20.1.1 from c:\python38\lib\site-packages\pip (python 3.8)
