Windows 3.0

In 3.0, Windows was officially released. Thanks to the huge improvements in Interface/human/memory management, Windows was finally recognized by users. After that, Microsoft launched the multilingual version of windows October 1991 in 3.0, which played a major role in the promotion of windows in non-native countries. In April 1992, windows 3.1 was released. In the first two months, sales volume exceeded 1 million. So far, Microsoft's capital accumulation/research and development has entered a virtuous circle.

This system includes both important improvements to the user interface and improvements to memory management technologies of 80286 and 80386. The program under the MS-DOS compiled for the command line operating system can run in the window, so that the program can be used on the basis of multi-task, although this version is only designed for home users, many games and entertainment programs still require DOS access.
