Windows 3.1x is a family of Windows versions following Windows 3.0 initially released on 6 April 1992. It added TrueType support and included multimedia components installed by default. System stability was greatly increased compared to Windows 3.0, while the user interface was refined and improved. Support for real mode was dropped, and in further updates, Standard mode was dropped as well. It was succeeded by Windows 95 released in 1995.

History[edit | edit source]

The first release was Windows 3.1 in 1992. Windows for Workgroups 3.1 was released alongside Windows 3.1 in 1992 and featured support for networking. It was updated to Windows for Workgroups 3.11 in 1993, whose core was also backported to Windows 3.1 as an update. A separate simplified Chinese release called Windows 3.2 was also made, fixing problems related to the input of Chinese characters.

Aside from the standalone version, Microsoft also released a combined bundle of MS-DOS 5.0 and Windows 3.1 codenamed Janus.[1] Later, with the release of MS-DOS 6.00, an updated version codenamed Jastro was released.[2]

Although Microsoft ended support on 31 December 2001, the OEM versions of Windows for Workgroups 3.11 on embedded systems were still available until 2008.[3]
