It's super impressive! But it won't run on 64 bit Windows.

I recently wrote a simple 32 bit Windows app that runs on 3.11 (with the 32 bit subsystem installed) through Windows 10. On the more recent Windows versions it supports theming and it's per-monitor high DPI aware. That is to say, it looks and works like a modern app.

To do this I had to build it as a freestanding binary with MingGW and do some version probing and dynamic DLL lookups but altogether it wasn't too hard.
