CD/DVD File System Reader is a file system driver. In Windows 7 it is disabled and therefore it isn't starting. If CD/DVD File System Reader 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 cdfs service is not running because of the error.
CD/DVD File System Reader is unable to start, if the CD-ROM Driver service is stopped or disabled.
