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.

1. Run the Command Prompt as an administrator.

2. Copy the commands below, paste them into the command window and press ENTER:

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.
