CMD commands allow the user to perform tasks on a computer without utilizing the Windows interface. These commands are normally only used by advanced users because they require familiarity with MS-DOS.
Command Prompt, or cmd.exe, is the command-line interpreter through which a user can input commands. To access it on Windows 7, press the Start button and type "Command Prompt" in the search box. Once the results appear, click on Command Prompt. This lets the user run MS-DOS and other computer commands. To access the full list of available commands, type "help" in the Command Prompt, and then press Enter.
