The Windows Command Prompt is a command-line interface in the Windows operating system that allows users to execute commands and perform various tasks. It provides a text-based environment where users can navigate files, run programs, and manage system settings without using a graphical interface. Users can access the Command Prompt by typing "cmd" in the Windows search bar or by navigating through the Start menu. It supports a range of commands, such as dir for listing files and copy for duplicating files, making it a powerful tool for advanced users and system administrators.
