The Users group will list all users of a local machine including Administrator users. I'm assuming this is XP Professional and not XP Home?

When a user logs in it loads their registry hive to HKEY_USERS. This is what EnumUsersReg does too except of course HKEY_CURRENT_USER remains the same.

You should put in a MessageBox after the call to LookupPrivilegeValue to see what $R0 is. It should be 0 on failure.
