If you’re talking about current #Windows and its NT heritage, it was bought *engineering*, specifically #DEC developers led by Dave Cutler.
Therefore, many elements of #WindowsNT’s design were inspired by DEC’s #VMS, #VAXELN, #RSX11, and (unreleased) #MICA operating systems.
#Microsoft eventually paid off DEC and supported NT on the latter’s #Alpha architecture machines rather than face a lawsuit.
