SCSI CD-ROM Driver by Microsoft Corporation.
|Display name:||CD-ROM Driver|
|Group:||SCSI CDROM Class|
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.
If CD-ROM Driver is stopped, the CD/DVD File System Reader service fails to start and initialize.
Restore Default Startup Configuration for CD-ROM Driver
1. Select your Windows 7 edition and service pack, and then click Download.
2. Save the Win7_cdrom_Service_Startup.cmd file to a local storage device.
3. Run the saved file as an administrator.
4. Restart the computer.
The cdrom service is using the cdrom.sys file that is located in the %WinDir%\system32\DRIVERS folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 7 installation media.
