I wonder how long it'll be before they release the source for the earliest Windows versions. The fact that they still have the source for this very old DOS at least gives hope that they also do for old Windows.
It shouldn't be hard to disassemble it.
I imagine its not far off. I get the impression they are almost done with windows as a platform.
I am sure that there is a lot good material to take inspiration and learning even from the early Windows 3.11.
They waited a couple decades too long for this to be of interest.
The day they would make Windows 2000 codebase open source (or source available) would be the day I could die happy (although I'd probably be long dead anyways by the time there's a glimmerof chance of it happening). What a beautiful, smooth-running operating system it was.
