Windows CD DVD Blu-ray Drives Not Recognized – Device Manager Entry Says “Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)”

I rebooted my laptop recently and found that my Blu-ray/DVD optical drive was no longer recognized. It was not showing the drive letter entry in Windows Explorer, and none of my DVD/Blu-ray player software recognized it anymore (Windows Media Player, WinDVD or PowerDVD). My virtual Blu-ray/DVD emulator – WinCDEmu – also had quit working. And when I tried plugging in my USB DVD drive, it too would not install the device driver!

After trying relentlessly to uninstall the drivers, reboot and re-install the drivers without any change, I decided to do a quick Google search to see what others may have similarly encountered and what success they had in resolving it.

I finally found a few situations that sounded promising – and a few suggestions were made which involved going into the windows registry and deleting some Keys off the CD-ROM drive ControlSet entries – LowFilters & HighFilters. When I did this, and once again uninstalled the drivers via Device Mananger, following an immediate reboot everything was back working again!

Here are the exact steps to follow:

  1. Open Registry Editor:
    • On Windows 2000 and XP: Choose Start > Run. Type regedit in the Open text box and click OK.
    • On Windows Vista: Choose Start. Type regedit in the Search text box, and press Enter.
  2. In the left pane of Registry Editor, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class and select the {4D36E965-E325-11CE-BFC1-08002BE10318} key, which appears as a folder.
  3. Select File > Export (Windows XP and Vista) or Registry > Export Registry File (Windows 2000).
  4. In the Export Registry File dialog box, select Selected Branch under Export Range, name the file (for example, CDDVDkey.reg), and click Save to save the file to the Desktop.
  5. In the right panel of the Registry Editor, select the LowerFilters line, and then choose Edit > Delete. Click Yes in the Confirm Key Delete dialog box.
  6. Select the UpperFilters line, and then choose Edit > Delete. Click Yes in the Confirm Key Delete dialog box.
  7. Close Registry Editor.
  8. Open Device Manager:
    • On Windows 2000 and XP: Choose Start > Control Panel. Double-click the System icon, click on the Hardware Tab, then click on Device Manager.
    • On Windows Vista: Choose Start > Control Panel, double-click System, then click Device Manager in the Tasks pane.
  9. Click on the plus symbol next to DVD/CD-ROM Drives.
  10. For each BD-ROM, DVD-ROM or CD-ROM drive listed, select the icon then choose Action > Uninstall.
  11. Restart Windows.
  12. Windows will automatically detect and reinstall your BD-ROM, DVD-ROM or CD-ROM drives. You can verify that the drives are installed by viewing them in Device Manager (see step 8). If the drives are not present, open Device Manger and choose Actions > Scan For Hardware Changes.
  13. Restart Windows.

Important: If this solution doesn’t resolve the problem with the application you reinstalled, then you should restore the CD and DVD drivers list in the Windows registry.

Best of luck – hope it works for you too!
