Default Behavior
CD-ROM Driver is a kernel device driver. In Windows 7 it is being loaded at Kernel initialization. If CD-ROM Driver 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 cdrom service is not running because of the error.
Dependencies
If CD-ROM Driver is stopped, the CD/DVD File System Reader service fails to start and initialize.
