I've recently dug up some of my first "larger" scale projects that I implemented in the early 2000's, including compiled executables, which managed to run unmodified on modern Windows.

That is an achievement in compatibility.

It was 2 demos of my game engine project, one compiled in late 2001 and the other in 2002 based on the exe file timestamps. They used Win32 and OpenGL, and surprisingly work faster on my laptop with integrated graphics than on my beast desktop PC.
