  • MS-DOS (since 1981), Microsoft operating system based on 86-DOS for x86-based personal computers
  • IBM PC DOS (since 1981), OEM version of MS-DOS for the IBM Personal Computer and compatibles, manufactured and sold by IBM from the 1980s to the 2000s
  • DR-DOS (since 1988), MS-DOS-compatible operating system originally developed by Digital Research
  • ROM-DOS (1989), MS-DOS clone by Datalight
  • PTS-DOS (since 1993), MS-DOS clone developed in Russia by PhysTechSoft
  • FreeDOS (since 1998), open source MS-DOS clone
