A version of Microsoft Windows released
in late 1987. Windows/386 was basically the same as its
predecessor, Windows/286 (as Windows 2 was renamed), but
with the capability to run multiple MS-DOS applications
simultaneously in extended memory.
An early version of Windows introduced in 1987. Using the Virtual 8086 Mode of the 386 CPU, it enabled multiple DOS applications to be run simultaneously. It was never very popular, but was the forerunner of the 386 Enhanced Mode in Windows 3.0, which was an outstanding success. See Windows.
