A lot of those were written in assembly by teenagers, using WinAPI directly. Yet they still run on Win10/Win11. A lost art.
This inspiration to build things that look like this is what has been lost.
It's not all about WinAPI, it's about the approach.
Today's approach is "let me use electron for GUI and python backend for my bitcoin monitoring app because it's convenient for me". This results in bundling 1 GB of code for a trivial project which is a pain to use.
And the "legacy" approach is "let me use masm32 and winapi because it will be enough".
