NT has NTVDM. It worked on many applications up until they added 64 bit into the mix. At which point they never ported it over. Once you move to any 64 bit version you can no longer do that and need a VM or DOSBox. https://en.wikipedia.org/wiki/Virtual_DOS_machine

Also NTVDM was kind of hit or miss. So if you are using a 32 bit version of any windows you may still get away with running many DOS and win16 applications. But within a particular set of limitations.

The only good NTVDM is the ReactOS' one. The one from MS itself is very flakey.

Try winevdm[1] or ntvdmx64[2], which I believe is based on leaked Microsoft source code. I've successfully gotten Tetris running on win10x64, and I'm happy enough with not needing dosbox+win3x for it.
