Microsoft DOS (Disk Operating System) is a command line user interface. MS-DOS 1.0 was released in 1981 for IBM computers. While MS-DOS is not used commonly today, it still can be accessed from Windows 95, Windows 98 or Windows NT by clicking Start / Run and typing command or CMD in Windows NT / 2000.

See the complete MS-DOS history by visiting our DOS section of our history section.

Additional information on computer Operating Systems can be found on our Operating Systems page.
