Abstract: A structure for identifying and modifying a computer operating system components includes a component table including a list of possible components of the operating system. An identifier structure is configured to access the component table and to interrogate the operating system to determine which components in the component table are loaded in the operating system. A build structure is coupled to the identifier structure and configured to compile identified components in the component table and to generate a table of the identified components. The resulting structure defines loaded components of the operating system and can then serve to assist additional structures in modifying the operating system. Modification structures search the table of loaded components to determine how to modify the operating system to achieve desired results. Advantages of the invention include the ability to identify and modify loaded components of the computer operating system.
