Seriously, the original NT Kernel was designed to be Posix compliant to run a UNIX environment. It eventually grew away from that but since Vista, Microsoft has been extricating unnecessary Win32 bits to Userland to take it back to it's roots. I think the MinWin project was completed prior to Windows 10 / Server 2016.

Linux was developed as a Unix compatible environment because Unix wasn't an option on commodity hardware. BSD isn't UNIX or Linux.

Why can't NT exist in the same area as a *nix compatible system?
