- Not to be confused with Windows 10.
Windows 1.0 is the first major release of the Microsoft Windows family of graphical operating systems for personal computers developed by Microsoft. It was released to manufacturing in the United States on November 20, 1985, while the European version was released as Windows 1.02 in May 1986.
Development began after Microsoft co-founder Bill Gates saw a demonstration of a similar software suite, Visi On, at COMDEX in 1982. The operating environment was showcased to the public in November 1983, but was not released until November 1985. Windows 1.0 runs on MS-DOS, as a graphical 16-bit shell known as MS-DOS Executive, and it provides an environment which can run graphical programs designed for Windows, as well as existing MS-DOS software. It introduced multitasking and the use of the mouse, and various built-in programs such as Windows Calculator, Paint, and Notepad. The operating environment does not allow its windows to overlap; instead, the windows are tiled. Windows 1.0 contains four releases, which contain minor updates to the system.
Despite positive responses to its early presentations and support from a number of hardware and software makers, Windows 1.0 was received poorly by critics, who felt that it did not meet their expectations. Among their concerns were performance issues on lower computer hardware specifications; not providing enough resources for new users and putting too much emphasis on mouse input at a time when mouse use was not widespread yet. Nevertheless, Windows 1.0 was an important milestone for Microsoft, as it introduced the Microsoft Windows line.[Citation needed] It was discontinued on December 31, 2001.[Citation needed]
History[]
Microsoft began developing a graphical user interface (GUI) in 1981 after founder Bill Gates saw a demonstration at COMDEX 1982 of VisiCorp's Visi On, a GUI software suite for IBM PC compatible computers.[Citation needed] In 1983 Microsoft learned that Apple's own GUI software—based in part on Xerox PARC technology—was much more sophisticated and decided that its own product would be different.
Windows 1.0 was first presented by Microsoft to the public on November 10, 1983, and the software required two floppy disk drives and 192 KB of RAM.[Citation needed] It was described as a device driver for MS-DOS 2.0. Windows 1.0 differed from both Visi On and Apple's Lisa in that it immediately offered many applications.[Citation needed] It didn't need to use Unix to develop IBM PC applications; Microsoft planned to encourage other companies, including competitors, to develop programs for Windows by not requiring a Microsoft user interface in their applications.[Citation needed]
