Windows NT was masterminded by Dave Cutler, who was previously responsible
for the VMS OS at his previous employer, DEC. He was a Unix-hater, part of
a bunch of them at DEC. They would instinctively turn away from Unix ways
of doing things, like forking multiple processes. So the systems they
created did not encourage such techniques.

Presumably VMS relied heavily on multithreading then like Windows or was a

Many system services on VMS are asynchronous, and the system
architecture provides a mechanisms to signal completion; ASTs,
mailboxes, etc.  Thus, many programs (not all) on VMS are
written in a callback/closure style.
