History[]
Windows 1.01 was first released on 20 November 1985. Version 1.02, released in May 1986, was an international release. Version 1.03, released in August 1986 included enhancements that made it consistent with the international release. It included drivers for European keyboards and additional screen and printer drivers. Version 1.04, released in April 1987, added support for the new IBM PS/2 computers, although no support for PS/2 mice or new VGA graphics modes was provided. At the same time, Microsoft and IBM announced the introduction of OS/2 and its graphical OS/2 Presentation Manager, which were supposed to ultimately replace both MS-DOS and Windows.
Windows 1.0 Beta (0.99) was the very-shortly-released framework of Windows 1.0 from March 1985, and was black and white, with fewer features than Windows 1.0.
In November 1987, Windows 1.0 was succeeded by Windows 2.0. Microsoft supported Windows 1.0 for 16 years, the longest out of all versions of Windows, until December 31, 2001.
