Downloading on Windows

Amazing, great work @brockdyer03!

@ghutchis re the installer format, see my previous comment in How to determine "stub" python on Mac and Windows - #6 by matterhorn103. Basically, to submit to the MS Store it is far easier if it’s an MSIX anyway (and possibly a requirement?), it’s a hard requirement for installation via winget, and it’s in general the modern and preferred format.
