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.

The cdfs service is using the cdfs.sys file that is located in the %WinDir%\system32\DRIVERS folder. If the file is corrupted or deleted, you can put it back in there.
