> The Windowsw NT kernel family is a clean-sheet design from the 1990s
I thought that the NT Kernel was heavily based on VMS.
When Dave Cutler, their chief OS architect/guru left for Microsoft and took a bunch of engineers with him. FTA:
"Why the Fastest Chip Didn't Win" (Business Week, April 28, 1997) states that when Digital engineers noticed the similarities between VMS and NT, they brought their observations to senior management. Rather than suing, Digital cut a deal with Microsoft. In the summer of 1995, Digital announced Affinity for OpenVMS, a program that required Microsoft to help train Digital NT technicians, help promote NT and Open-VMS as two pieces of a three-tiered client/server networking solution, and promise to maintain NT support for the Alpha processor. Microsoft also paid Digital between 65 million and 100 million dollars."
