Windows 3.0, a graphical environment, is the third major release of Microsoft Windows, and was released on May 22, 1990. It became the first widely successful version of Windows and a rival to Apple Macintosh and the Commodore Amiga on the GUI front. It was followed by Windows 3.1.[2]
Windows 3.0 originated in 1989 when David Weise and Murray Sargent independently decided to develop a protected mode Windows as an experiment. They cobbled together a rough prototype and presented it to company executives, who were impressed enough to approve it as an official project.
