A registry key must start with "HKEY_LOCAL_MACHINE" ("HKLM") or "HKEY_USERS" ("HKU") or "HKEY_CURRENT_USER" ("HKCU") or "HKEY_CLASSES_ROOT" ("HKCR") or "HKEY_CURRENT_CONFIG" ("HKCC").
When running on 64-bit Windows if you want to enum a key specific to the 64-bit environment you have to suffix the HK... with 64 i.e. HKLM64.
