Default Behavior

The CD-ROM Driver service is a kernel device driver. In Windows 8 it is being loaded and initialized at Kernel initialization. If CD-ROM Driver 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 cdrom service hasn't been started.

Restore Default Startup Configuration for CD-ROM Driver

1. Select your Windows 8 edition and update pack, and then click Download.

2. Save the Win8_cdrom_Service_Startup.cmd file to a local storage device.

The cdrom service is using the cdrom.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.
