Answer 1

The easiest method would likely be just uninstalling and reinstalling pip. Since this is a Microsoft product, you may need to go through the files and registry to ensure it cleans out all the old data and paths before reinstalling. But I would do that only if a regular uninstall and reinstall doesn't work.

You can also manually check the paths used by things. In windows see here as an example.
