RegNotifyChangeKeyValue - how do I know which key has changed when using subtree=true ?

Does anyone know how to use RegNotifyChangeKeyValue ?

I need to monitor all changes in a top level key, i.e.
HKEY_CLASSES_ROOT, so I am using the bWatchSubtree flag.
My problem is how do I know which subkey has changed. Surely I
don't need to enumerate all the possible paths and issue this api per
each path, that would be unreasonable, wouldn't it?
