The Enum subkey contains a database representing all devices installed on the computer and recognized by the system. The database stores configuration data for hardware devices independent of the drivers they use. This subkey is critical to the configuration of Plug and Play devices in Windows.
To change device settings, use Device Manager.
Users, including administrators, cannot change the contents of the Enum subkey. These restrictions protect the integrity of the operating system and the devices on the computer.
Do not attempt to change the permissions on the Enum subkey. If you do, you might damage the sequence of inherited permissions in the registry. If you change the content of the Enum subkey, you can damage the Plug and Play functions of Windows Server 2003 and prevent devices from operating. If you must gain access to the Enum subkey, contact Microsoft Product Support Services.
