Adding / removing icons in Windows control panel.

Issue:

Adding / removing icons in Windows control panel.

Cause:

Missing Control Panel icons can be caused by any of the below possibilities.

1. Control Panel icon was deleted or has become corrupt.
2. Related software program or hardware device has been uninstalled or is no longer being detected by Windows.

Additional Information:

Microsoft Windows stores information about each of the icons that are shown in the control panel in files with the extension .CPL. If these files are present and not corrupted Microsoft Windows will display these icons otherwise these icons will not be visible. The control panel files are often found in the C:\Windows\System, C:\Windows\System32, or C:\Winnt\system32 directories once the hardware device or software program related to the icon has been installed.

Solution:

Adding Windows control panel icons

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 below steps.

1. Reinstall the software program or hardware device associated with the program. This should copy the the necessary .CPL file back onto the computer. 
2. Manually copy, expand, and/or extract the .cpl file back into the Windows System or System 32 directory.

Note: Unless your software program or hardware device has a .cpl file associated with it the program will not create an icon in your control panel. 

Manually testing or running a Windows Control panel .cpl file

If you are unfamiliar with what each .CPL file 

1. Users can use the MS-DOS control file to execute many of the .CPL files by typing "control <name of .cpl file>.cpl".  
2. Users can also use the rundll32 file to open the control panel icons. Below is an example of how a user would open the Date/Time Properties window using the rundll32 file. If you wish to run an alternate .cpl file replace the TimeDate.cpl with a different .cpl. 

rundll32.exe shell32.dll,Control_RunDLL TimeDate.cpl

Removing Windows control panel icons

Using the Microsoft Find utility users can locate all .cpl files on their computer.

Once all the .cpl files have been found, locate the file associated with your icon and delete the file or move it to an alternate location.
