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/System32 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.
