Windows exposes personalities above the kernel, in the NT days that meant OS/2 1.x, POSIX and Win32.
Nowadays on Windows 10 it means UWP, Win32 and Linux syscalls.
In theory someone could call the ntdll.dll and create a new personality but those APIs are undocumented and only possibly made available to Microsoft partners.
