Originally, OS/2 was a joint development between Microsoft and IBM.
Though eventually they split up, and Microsoft went on to emerge Windows NT from what was originally known as NT OS/2 3.0. So does Windows NT have an OS/2 personality after all?

The Operating System known as Windows NT shares many similarities with DEC's VMS. Not for bad reason, as Microsoft hired renowned developer David N. Cutler to take the lead on the next iteration of OS/2 3.0.
However, the project took an entirely different direction, with OS/2 ending up just one of 4, later 5 operating system subsystems hidden inside Windows NT.
Today we look into the OS/2 personality of Windows NT 3.x, and how compatible it actually was.
