Windows 3.1

Windows 3.1 introduced several new technologies onto the Windows 3.0 platform. The most notable was True type fonts, and OLE. The 'real mode' was removed, as Windows 3.1 now executed in protected mode only.

Windows 3.1 is more of an 'environment' then an operating system, as it still uses MS-DOS for some functions, and the 386 enhanced mode spawns VDM's with MS-DOS.

Microsoft also included basic multimedia API's facilitating the playback of MIDI files, and wav audio files.

Modes of operation

Windows 3.1 dropped the realmode from Windows 3.0, while retaining both standard & 386 Enhanced modes. Both modes functioned identically as they did in Windows 3.0
