Windows 3.1 is a series of 16-bit operating
systems produced by Microsoft for use on
personal computers. The series began with
Windows 3.1 (codenamed Janus), which was first
sold during March 1992 as a successor to Windows
3.0
Windows 3.1 includes a TrueType font system,
which effectively made Windows a serious desktop
publishing platform for the first time. Similar
functionality was available for Windows 3.0
through the Adobe Type Manager (ATM). Windows
3.1 was designed to be backward compatible with
older platforms.
Windows 3.1 Multimedia Version (codenamed
Bombay) included a media viewer, and the ability
to play video files. It was targeted to the new
multi-media PC and included sound and video
integration with CD-ROM support.
The 3.1 series was superseded by Windows 95.
