Command Prompt

Command Prompt in Windows 7

Command Prompt is the name for the program provided with the Windows operating system which allows the user to access the computer shell, that is, a text-based (command-line) control system.

One can open the Command Prompt window by clicking the Start button, clicking All Programs, clicking Accessories, and then clicking Command Prompt. Alternatively, "cmd.exe" can be entered into the Run/Search box to start it immediately.
