Windows NT 3.1 was the first of the Windows NT series. Sporting the same face as its consumer counterpart Windows 3.1, it was completely different under the hood. A true 32-bit native operating system, Windows NT descended from the work Microsoft did while collaborating with IBM on OS/2 after the great split, and bringing in former DEC employees like Dave Cutler, bringing a VMS influence into the system. It was followed up by Windows NT 4.0.

| 1.0 | 2.x | 3.x | NT 3.x | 95 | NT 4.0 | 98 | 2000 | ME | All |
