Windows 3.1x

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
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. Later, with the release of MS-DOS 6.00, an updated version codenamed Jastro was released.

Although Microsoft ended support on 31 December 2001, the OEM versions of Windows for Workgroups 3.11 on embedded systems were still available until 1 November 2008.

Easter Eggs
Windows 3.1 featured two very different easter eggs, much like the previous versions, which also contained easter eggs.

The first of these Easter eggs is similar to the one seen in Windows 3.0, in that it shows the names of the Windows 3.1 development team. To access this easter egg, start by holding down Ctrl+Alt+Shift, then go to the Help menu and click "About Program Manager". Next, double click on one of the Windows logo tiles and press OK, then do it again to another tile. You will eventually get a message that reads "Dedicated to all the hard-working people of the Microsoft Windows 3.10 Team!" alongside an animated Windows logo on a flag. Doing this procedure a third time, you should be able to get a scrolling list of all the developers, albeit in the form of their email handle.

The second Easter egg actually involves the first one. In some instances, you get a guy in a yellow suit presenting all the Windows 3.1 developers. If you are to do the same process multiple times, there's a chance you'll get a bear in a yellow suit, which is a reference to the Windows 3.1's developer team's mascot.
