Details

Summary
This was the first successful OS for the IBM PC platform, and was chosen by IBM for its PCs. Each major version added considerable improvements, but today is quite dated. Typical usage is with a command line interface, but a number of shells were produced that allows avoidance of the command line. Microsoft licensed MS-DOS to IBM, which produced their minor variant PC-DOS. DOS still lives on, as most functions are supported under Windows and Linux.

News
MS-DOS is no longer sold or supported by Microsoft, but the commands can be run from a “DOS box” of Windows.
All sales in all channels were discontinued in November 31, 2001.
