It's true that one of the original architects of Windows NT was previously a senior architect of VMS. No doubt he took some of the good ideas with him, and early on in Windows versions, it was possible to see similar concepts as there are in VMS. However Windows never (still hasn't...) got anywhere near the reliability of VMS - the usual joke inside digital was when VMS had to reengineer the up time display to allow more digits, because there were systems that had not been rebooted for several years, I think the record was something like sixteen years...
Later it was discovered that MS had "accquired" the source code to clustering from VMS, and although digital cut a deal with MS (rather than suing their a****s off !!) so that MS could legally use the algorithms, Windows has still not got a clustering system that remotely compares with the almost transparent way that clusters work in VMS.
