Yes, many like to bash Windows, but the NT family is actually a VMS at heart, spoiled by a not so good user land experience.

I once attend a session by him about the Windows kernel design, quite interesting.

VMS + 1 = WNT, in the same way as IBM - 1 = HAL.

(So far as I know, both of these are just amusing coincidences.)

I once went through the VMS documentation, and could at least find some of the design ideas that I knew from Windows NT.

I think it is good that the industry enjoys different types of OS architectures and designs.

Just because UNIX managed to spread as it did, doesn't mean it is the be all of OS design. After all, its creators tried to fix UNIX, just the industry did not adopted it.

In the 2001 audio book Arthur C Clarke had a 15 minute intro where in it (amung other things) he explicitly says it is a coincidences and lists the page in the book explaining what HAL stands for.
