Retrieving information form from the registry include by creating a registry interface database containing information regarding registry data and uniquely identifying every registry entry for a registry interface. Source header files are generated using information about a program module, such as an application, contained in the registry interface database. The source header files are compiled with the application to generate the application's executable file. During run-time of the application, the registry interface is called by the application to retrieve registry data. If available, the registry interface retrieves the registry data and forwards this information to the application. In the event that the registry data is not available, the registry interface retrieves a default value in place of the registry data and forwards that default data to the application. A policy may be implemented by checking a policy area of the registry for the registry data and invoking the policy.
