This set of topics discusses how to implement the extension handlers that allow you to modify a variety of Shell actions. The handler can then specify additional menu items on a file-by-file basis, rather than having the same set for all files of that file type. If one is implemented for a file type, it will be queried every time one of the files is right-clicked. A common example is a shortcut menu extension handler. Before taking the action, the Shell queries the extension handler, giving it the opportunity to modify the action.

These handlers can be implemented for a variety of actions that the Shell can take. Other aspects of the Shell, such as the Properties property sheet that can be displayed when a file is right-clicked, cannot be modified at all with the registry.ДЄ more powerful and flexible approach to extending the Shell is to implement shell extension handlers. Extending the Shell with the registry does not allow you to vary the icon for different members of the file type. For example, if you use the registry to specify a custom icon for a file type, the same icon will appear for every file of that type. While this approach to extending the Shell is simple, and adequate for many purposes, it is limited. The capabilities of the Shell can be extended with registry entries and.
