Microsoft Windows
Microsoft Windows, commonly known as Windows, is a proprietary graphical operating system developed and marketed by Microsoft.
It is grouped into families that cater to particular sectors of the computing industry – Windows for personal computers, Windows Server for servers, and Windows IoT for embedded systems. Windows itself is further grouped into editions that cater to different users – Home for home users, Professional for advanced users, Education for schools, and Enterprise for corporations. Windows is sold both as a consumer retail product and to computer manufacturers, who bundle and distribute it with their systems.
The first version of Windows, Windows 1.0, was released on November 20, 1985 as a graphical operating system shell for MS-DOS in response to growing interest in graphical user interfaces (GUIs). The name Windows is a reference to the windowing system in GUIs. The 1990 release of Windows 3.0 catapulted its market success and led to various other product families, including the (now-defunct) Windows Mobile, Windows Phone, and Windows CE/Embedded Compact.
Windows is the most popular desktop operating system in the world, with a 72% market share as of October 2025[update], and the second-most popular operating system overall, behind Android. As of August 2025, Windows 11 is the most used desktop version of Windows, with a market share of 53%.
As of 2025,[update] the only active top-level family is Windows NT.[citation needed] The first version, Windows NT 3.1, was intended for server computing and corporate workstations. It grew into a product line of its own and now consists of four sub-families that tend to be released almost simultaneously and share the same kernel.
These top-level Windows families are no longer actively developed:
The term Windows collectively describes any or all of several generations of Microsoft operating system products. These products are generally categorized as follows:
The history of Windows dates back to 1981 when Microsoft started work on a program called "Interface Manager". The name "Windows" comes from the fact that the system was one of the first to use graphical boxes to represent programs; in the industry, at the time, these were called "windows" and the underlying software was called "windowing software." It was announced in November 1983 (after the Apple Lisa, but before the Macintosh) under the name "Windows", but Windows 1.0 was not released until November 1985. Windows 1.0 was to compete with Apple's operating system, but achieved little popularity. Windows 1.0 is not a complete operating system; rather, it extends MS-DOS. The shell of Windows 1.0 is a program known as the MS-DOS Executive. Components included Calculator, Calendar, Cardfile, Clipboard Viewer, Clock, Control Panel, Notepad, Paint, Reversi, Terminal and Write. Windows 1.0 does not allow overlapping windows. Instead, all windows are tiled. Only modal dialog boxes may appear over other windows. Microsoft sold as included Windows Development libraries with the C development environment, which included numerous windows samples.
