Lire une sub-key du registreRésolu

Question

Bonjour, 
Je sais comment lire le contenu d'une clé du registre mais comment faire si on ne connait pas le nom de la sub-key ?
Exemple :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces
cette clé contient 3 sous-répertoires aux noms rébarbatifs
{77079887-e3a5-4cba-8b9c-015b464834f1}
{7f3a3952-db7a-11e7-9da7-806e6f6e6963}
{81875a5a-5226-4642-89ce-7841d9d4a8c1}
comment faire pour les parcourir jusqu'à trouver le nom que je cherche et sa valeur ?
