Usually WINDOWS comes with its own CD-ROM drive, so you don't need to add it. If the driver of the optical drive is not installed with its own driver, the optical drive will also be lost. This situation usually occurs by adding so-called "optimization", "acceleration program" or other programs. At this time, you can enter the safe mode, delete the "CDROM" option in the device manager, and then restart the computer, so that the system can find new hardware and reinstall the driver of the CD-ROM drive.
