MessageDavid, When you say "it does not add that key to USERS", what are you expecting to see? For each logged-in user, the HK_USERS should contain two entries....one with his/her SID and another with SID_Classes. HK_Current_User is merely your own personal link to the USERS entry with your SID. You can tell who is currently logged in by determining the owner of each entry in USERS.
