Use DeleteRegKey to update the system registry.

Note: DeleteRegKey is useful for implementing the UpdateRegistry method of a class factory.

DeleteRegKey deletes the subkey of RootKey that is passed in as the Key parameter.

Key must specify a null-terminated string, which is the name of the key to delete. It cannot be NULL. The Key to delete must not have subkeys.

RootKey is the top-level key under which the key to delete appears. It defaults to HKEY_CLASSES_ROOT.

If DeleteRegKey succeeds it removes the entire specified key from the registry, including all of its values. An exception is raised if it fails.
