IShellExtInit 

The IShellExtInit interface is used to initialize shell extensions for property sheets, context menus, and drag-and-drop handlers (extensions that add items to context menus during non-default drag-and-drop operations).

When to Implement

Implement IShellExtInit when you are writing a handler based on IContextMenuGAKT5J or IShellPropSheetExt1N3DJ.O.

Note that shell extensions based on other interfaces do not use this method of initialization

When to Use

You don t use this interface directly. It is called by the shell to initialize the handler.
