Windows 3.1
series of 16-bit operating systems, produced by Microsoft for use on personal computers, that was released on April 6, 1992
Windows 3.1 is a consumer-oriented operating system developed by Microsoft, released to manufacturing on April 6, 1992. Unlike its predecessors, which ran as a shell on top of MS-DOS, its 386 Enhanced Mode functioned as a virtual machine monitor virtualizing DOS as a guest. It was the last Windows 16-bit operating system, after which future versions of Windows moved to 32-bit.
Windows 3.1 introduced the TrueType font system as a competitor to Adobe Type Manager. Its multimedia was also expanded, and screensavers were introduced, alongside new software such as Media Player (also known as "Windows Media Player") and Sound Recorder. File Manager and Control Panel received tweaks, while Windows 3.1 also saw the introduction of the Windows Registry and add-ons, and it could utilize more memory than its predecessors.
Microsoft also released special versions of Windows 3.1 throughout 1992 and 1993; in Europe and Japan, Windows 3.1 was introduced with more language support, while Tandy Video Information System received a special version, called Modular Windows. In November 1993, Windows 3.11 was released as a minor update, while Windows 3.2 was released as a Simplified Chinese version of Windows 3.1. Microsoft also introduced Windows for Workgroups, the first version of Windows to allow integrated networking. Mostly oriented towards businesses, it received network improvements and it allowed users to share files, use print servers, and chat online, while it also introduced peer-to-peer networking.

Why this record matters
“Windows 3.1” is worth following because a concise public description often conceals a longer documentary argument. Here, Windows, series and 16-bit provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 7, 2026. The linked authority identifier is Q495432. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1992 and 1993.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
