Perhaps, if there are some very specific compatibility issues that haven't been solved yet.
That said, MS-DOS 4 isn't even the most recent version, the last one was 6.22 to my knowledge, and IIRC a lot of games tended to require at least version 5 or 6.
Ctrl+alt+delete was a separate interrupt line direct from the keyboard. That is, when you pressed the three keys, the interrupt signal was asserted, causing the CPU to jump to the interrupt service routine, which should be in the source code package.
MS-DOS, Source public available on March 25 2014 with MS Research License, released with as Free Software MIT license in 2018, this yer released as Open Source MS-DOS 4.0.
Anyway, the Source code was available since 2014, only different licenses since then.
Probably yeah, but now they've officially released it under the MIT license so stuff like Wine could now potentially borrow some code to improve compatibility with Windows
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
