Microsoft Windows

Microsoft Windows is a brand of PC operating system families created Microsoft. The consumer versions were first based on MS-DOS until the Windows NT kernel, originally designed for workstations and network servers, began being used for all of Microsoft's general purpose PCs. Windows is thus the most popular PC operating system in the world.

The Xbox One's operating system is also based on Windows.
