It is not easy being Microsoft.

POSIX.1 was created in 1988. Microsoft released POSIX for
Windows in 1993. POSIX.1c threads was created in 1995 and
POSIX sockets was added even later (2008??).

What did you expect MS to do? Invent a time machine so they
after those newer standards got defined could go back in time
and make their product compliant?

Windows Subsystem for Linux (WSL).

It is a general Linux emulation where MS supports several
distros. Ubuntu was probably the first leading to the common
misconception that it is an Ubuntu thing.
