Windows 1.0 is a 16-bit graphical operating environment released on November 20, 1985. It was Microsoft's first attempt to implement a multi-tasking graphical user interface-based operating environment on the PC platform.

First window (in window form) appeared in personal computer was by Apple Computer.

Microsoft first began development of the Interface Manager (subsequently renamed Microsoft Windows) in September 1981.
Although the first prototypes used Multiplan and Word-like menus at the bottom of the screen, the interface was changed in 1982 to use pull-down menus and dialogs, as used on the Xerox Star.
Microsoft finally announced Windows in November 1983, with pressure from just-released VisiOn and impending TopView.
This was after the release of the Apple Lisa, and before Digital Research announced GEM, and DESQ from Quarterdeck and the Amiga Workbench , or GEOS/GeoWorks Ensemble, IBM OS/2, NeXTstep or even DeskMate from Tandy.
Windows promised an easy-to-use graphical interface, device-independent graphics and multitasking support.
The development was delayed several times, however, and the Windows 1.0 hit the store shelves in November 1985. The selection of applications was sparse, however, and Windows sales were modest.
