If System Attribute Cache fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the discache service is not running because of the error.
Dependencies
If System Attribute Cache is stopped, the AppID Driver service fails to start and initialize.
