Updated October 05, 2019 121 121 people found this article helpful DOS commands are the commands available in MS-DOS that are used to interact with the operating system and other command line based software. Unlike in Windows, DOS commands are the primary way in which you use the operating system. Windows and other modern OSs use a graphics-based system designed for touch or a mouse. DOS Commands in Windows: If you use Windows (like Windows 10, 8, 7, etc.) then you have no need for DOS commands because you don't have MS-DOS. The commands in Windows are available from the Command Prompt and are called Command Prompt commands or CMD commands, but they are not DOS commands. Instead, check out our List of Windows CMD Commands for all of the command-line options you have available to you in Windows. We also have a command comparison table to show which commands are available in different Microsoft operating systems.
