remove all versions of python and by rightclicken on them end pressing uninstall, this will open the programs and features panel and just remove all versions of python you have there, then install the latest version via the python website. this process will not take very long.
There are many answers on how to remove old Python versions and many on how to install new ones. Is there a way to install the latest Python version so that it replaces all old installations please?
I don't want to use a virtual environment, BTW.
I only want the latest version of Python on my Windows machine
