How to: Windows 8.1 CD Drive, DVD Drive not visible in File Manager.
After installing Windows 8.0, Windows 8.1, the CD/DVD drive does not appear in My Computer, FileManager, Windows Explorer or in the Control Panel under devices. CD or DVD drive is missing or not recognized by Windows or other programs. ...and yet the CD worked during the install.
Error: The device is not working properly because Windows cannot load the drivers required for this device (Code 31).
Error: A driver for this device was not required, and has been disabled (Code 32 or Code 31).
Error: Code 19, Code 39, "Windows successfully loaded the device driver for this hardware but cannot find the hardware device (Code 41).
Unknown. But symptoms appear if you upgrade the Operating System (Windows 8.0 to 8.1); installed a new operating system; possibly un-installed Microsoft Digital Image.
Microsoft suggests 5 different solutions, but this is the one that has worked for me on multiple machines.
