Reads data and the simplified data type from a registry value. If the key or value does not exist or an unrecoverable error occurs, the VI returns the default data. Wire data to the default data input to determine the polymorphic instance to use or manually select the instance.

Caution Incorrectly modifying the registry can damage Windows or prevent you from starting Windows.
