One version for all and all are defunct except 11 for ARM64 and 11 for ARM64 runs like shit on everything but a VM for an Arm Mac (A Mach BSD UNIX, btw)>durr ia-32 and amd64 are different platforms
No, they're not. AMD64 is binary-compatible with IA-32.
I only count 'run' as being usable. That disqualifies ARM32 from the get-go (WinRT)
All the others are some obscure-shit NT4 build that didn't even get service packs, or in the case of the itanic, an unupdated 5.1 and an unupdated 5.2 build. Both are not usable, and if you got a modern PowerPC system for example, you, de facto, would not be able to run WIndows on it. This goes for Arm64 systems, even, on everything but MS hardware and VMs. How's bootcamp for Apple Silicon going?
So no, NT is not cross-platform in practice, it is x86-centric.
Also, OS/2 and DOS are MS products too while NT was developed by transplants from DEC's VMS, a minicomputer vendor that was also responsible for UNIX, and the early beginnings of Linux through the Alpha (that Windows NT dropped after 4.0 btw), the C:\ stuff is designed to look like DOS (TENEX-like)
Mac, isn't listed, neither the classic Mac OS or NeXTSTEP/MacOSX either, so NSGODS stay NSWINNING
