In addition to normal Component Object Model (COM) registration, the following steps must be completed in order to register icon overlay handlers.

Instructions

Step 1: Create a subkey named for the handler under this key

HKEY_LOCAL_MACHINE
   Software
      Microsoft
         Windows
            CurrentVersion
               Explorer
                  ShellIconOverlayIdentifiers

Step 2: Set the default value of the subkey to the string form of the object's class identifier (CLSID)GUID

The following example illustrates how to register an icon overlay handler named MyOverlay.

HKEY_LOCAL_MACHINE
   Software
      Microsoft
         Windows
            CurrentVersion
               Explorer
                  ShellIconOverlayIdentifiers
                     MyOverlay
                        (Default) = {MyOverlay CLSID GUID}
