Microsoft had worked with [[Apple Inc.|Apple Computer]] to develop applications for Apple's January 1984 [[Macintosh 128K|original Macintosh]], the first mass-produced personal computer with a [[graphical user interface]] (GUI) that enabled users to see user friendly icons on screen. Windows 1.0 was released on November 20, 1985, as the first version of the [[Microsoft Windows]] line. It runs as a graphical, 16-bit multi-tasking shell on top of an existing [[MS-DOS]] installation. It provides an environment which can run graphical [[Computer program|programs]] designed for Windows, as well as existing [[MS-DOS]] software. Its development was spearheaded by the company founder [[Bill Gates]] after he saw a demonstration of a similar software suite known as Visi On at COMDEX. 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. Critics felt Windows 1.0 did not meet their expectations. In particular, they felt that Windows 1.0 put too much emphasis on [[mouse (computing)|mouse]] input at a time when mouse use was not yet widespread; not providing enough resources for new users; and for performance issues, especially on systems with lower [[computer hardware]] specifications
