Default Behavior

The CD/DVD File System Reader service is a file system driver. In Windows 8 it is disabled and therefore it won't start under any conditions. If CD/DVD File System Reader fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the cdfs service hasn't been started.
