What is a CPL file?
A CPL file is a control panel item, such as Displays, Mouse, Sound, or Networking, used by the Windows operating system. It is stored in the Windows\System folder and loaded automatically when the Windows Control Panel is opened.
Since CPL files are referenced by the Windows operating system, they should not be opened manually.
