(This is a long 5600+ words post, I recommend reading this from a tablet or computer) Windows for Workgroups 3.11 (WFW3.11) was an operating system (OS) released by Microsoft in August 1993 and ended support in December 2001. It is part of a series of OSes released by Microsoft at that time so it is common for people to refer to it as part of Windows 3.1x (Win3.1). The specific history behind its name and version number and be found on its Wikipedia article. Here is a brief list of first-impressions I have if I were to describe this OS. First Windows OS to have practical (installable) networking capabilities Last one to not have a Start Menu and legacy interface before Windows 95 Last OS to require DOS as an initial install Last 16-bit OS Here is a teaser screenshot showing that I managed to get WFW3.11 installed on a “modern” 2009 Thinkpad T400 with networking capabilities. Recognise some familiar applications there?
