DOS stands for “Disk Operating System“. It is an acronym for many closely related operating systems that dominated the IBM PC compatible market from 1981 until 1995 or until about 2000 including the partially DOS-based Microsoft Windows versions 95, 98, and Millennium Edition.

Related systems include MS-DOS (Microsoft Disk Operating System), PC DOS, and its ancestors 86-DOS, DR-DOS, FreeDOS, and RxDOS as well as PTS-DOS, ROM-DOS, Embedded DOS, and ZDOS.

What happened to DOS?

Technically speaking, Microsoft retired MS-DOS, so there will be no more updates for this operating system.

Still, this version of DOS remains popular around the world, especially for some specialists and IT enthusiasts. Also, MS-DOS has many embedded applications.

The first versions of DOS were simple but in time, subsequent versions became increasingly sophisticated. Still, DOS remained a 16-bit operating system and it doesn’t support multitasking or more than one users.

Can I still use DOS?

Well, yes, but it is easy to see why DOS is outdated and insufficient for many modern computer applications.

However, there are emulators that make DOS run in the latest versions of Microsoft Windows, such as MS-DOS Player which allows Windows 10 to run DOS programs and ConEmu, a powerful, multi-tab Windows console emulator.
