registry

To hide unused applets using the Registry, run the Registry Editor (run > type regedit) and go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Control Panel\don't load The key, as its name implies, determines which Control Panel applet icons are not loaded into the Control Panel. You’ll still be able to run those applets from the command line after you hide them  you just won’t be able to see their icons in the Control Panel.

To hide an applet, create a new String value whose name is the filename of the applet that you want to hide. For example, to hide the Mouse Control dialog box, the String value would be main.cpl. Below are the complete list of Control Panel applets and their filenames.
