Citat:
Users can add a Windows Control Panel icon by installing the software program or hardware device related to the icon. If doing this does not install an icon into the Windows Control Panel that is either listed in the below chart or has been present in the past, follow the steps below.
Reinstall the software program or hardware device associated with the program. This should copy the necessary .CPL file back onto the computer.
Manually copy, expand, and extract the .cpl file back into the Windows System or System 32 directory.
