To run a Control Panel tool in Windows, type the appropriate command in the Open box or at a command prompt.
NOTE: If you want to run a command from a command prompt, you must do so from the Windows folder. Also, note that your computer may not have all of the tools listed in this article, as your Windows installation may not include all of these components.
NOTE: The Scanners and Cameras applet (sticpl.cpl) cannot be run in Windows Millennium. It has been replaced by the Scanners and Cameras Folder, which is similar in function to folders like Printers and Dial-up Networking.
Windows substitutes the name of the tool you want to run for %1%. For example:
To run the Users tool for Windows 95/98/Me, type "control inetcpl.cpl users" (without the quotation marks) and then press ENTER.
