These are my random thoughts about MS Windows for x86... IMHO, we can speak about few time periods:
--------------------
198x - Windows 1.x, 2.x
--------------------
1990 - Windows 3.0. First more widely accepted and used
1992 - Windows 3.1 (Janus). Only protected mode, new: True Type fonts
1993 - Windows 3.11. APM
Summary: 16-bit time. Microsoft cooperated with IBM and there was OS/2 created during this time. First tries of making graphic subsystem (there was DirectX from it created). There were first network releases (Windows for WorkGroups).
