Thank you for WinPython!

According to python.org (https://www.python.org/downloads/windows/), Python 3.9.2 cannot be used on Windows 7 or earlier.

Which versions of WinPython can be used with Windows 7? If you provide the info, I'm happy to update the README for you.

Also, https://winpython.github.io/ needs to be updated with this essential information, and I'm happy to help with that as well.
