Knowledge Points:
The CPL file, also called Control Panel item, is stored in the System32 folder of the system installation directory, which corresponds to the items in the Control Panel, and the access of ordinary users is limited. It can be opened by Shell32.dll, Control.exe. Alternatively, you can double-click the Open command directly in the explorer (essentially calling Shell32.dll).
The CPL file is essentially a Windows executable file, but it is not a file that can be run directly independently, usually by Shell32.dll.
Most of the CPL files in the System32 directory are Windows system files with the archive file attribute, and the Windows operating system's File protection protects them from tampering.
