Would it be possible to run Windows 3.x under NTVDM?

Rot

Crossed my mind and I got curious about it. If not, why not?

I know 16-bit Windows programs and the Windows 3.x Program Manager can run under NTVDM, but what about actual Windows 3.x?

Mabye even Windows 9x?

Win9x requires too much direct access to hardware.

Keep in mind that NTVDM itself runs a customized Windows 3.1 for 16-bit compatibility.

I've run Windows 1 and 2 in 9x DOS boxes before.

But with Windows 3.1 you would have to massively scale back what it tried to access (no mouse, no direct file system access). I don't recall what the specific limiting factor(s) are, but I don't recall that it would work.

But knock yourself out if you want to try.
