Page "History of Microsoft Windows" Paragraph 29

In response to the impending release of OS / 2 2. 0, Microsoft developed Windows 3. 1, which included several minor improvements to Windows 3. 0 ( such as display of TrueType scalable fonts, developed jointly with Apple ), but primarily consisted of bugfixes and multimedia support.

It also excluded support for Real mode, and only ran on an 80286 or better processor.

Later Microsoft also released Windows 3. 11, a touch-up to Windows 3. 1 which included all of the patches and updates that followed the release of Windows 3. 1 in 1992.

Around the same time, Microsoft released Windows for Workgroups ( WfW ), which was available both as an add-on for existing Windows 3. 1 installations and in a version that included the base Windows environment and the networking extensions all in one package.

Windows for Workgroups included improved network drivers and protocol stacks, and support for peer-to-peer networking.

One optional download for WfW was the " Wolverine " TCP / IP protocol stack, which allowed for easy access to the Internet through corporate networks.

There were two versions of Windows for Workgroups, WfW 3. 1 and WfW 3. 11.

Unlike prior versions, Windows for Workgroups 3. 11 ran in 386 enhanced mode only, and needs at least an 80386SX processor.
