Maybe a shortcut of Dave Cutler plus what Wikipedia said "While creating Windows NT, Microsoft developers rewrote VMS in C. Although they added the Win32 API, NTFS file system, GUI, and backwards compatibility with DOS, OS/2, and Win16, DEC engineers almost immediately noticed the two operating systems' internal similarities; parts of VAX/VMS Internals and Data Structures, published by Digital Press, accurately describe Windows NT internals using VMS terms. Instead of a lawsuit, Microsoft agreed to pay DEC $65–100 million, help market VMS, train Digital personnel on Windows NT, and continue Windows NT support for DEC Alpha" Also https://www.itprotoday.com/compute-engines/windows-nt-and-vms-rest-story https://www.itprotoday.com/compute-engines/windows-nt-and-vm...
