For the most part probably not, but Microsoft cares a lot about backwards compatibility so I imagine some of this code still lives on in Windows

Though you should take this with a grain of salt, since I'm saying this as someone who 1. never looked at Wine source code 2. used the Windows API only once, for a very small program 3. is still learning programming, so I wouldn't call myself a coder (yet) either

yeah there are even still some remaining windows 3.0 dialogues used in the latest win11

As someone with an IBM PS/1 running 4.0, I'm excited to be able to modify it, distribute it, etc
