I went to use my Blu-Ray player to load on my recently purchased Lenovo A720 all-in-one PC and found it not working. It is running Windows 8.

I opened the Device Manager from the Control Panel and the Blu-Ray player was showing with a yellow warning sign in the device lists. The name of the device was PLDS DS-6E2SH BD-COMBO.

When I double clicked and examined the device, the exact error message was:

“Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)”

I tried uninstalling and re-installing the device using the automatically discovered drivers (with and without rebooting). I tried to update the drivers as well, but still had no luck.

Solution That Worked For Me

I searched around and found a variety of possible solutions, but only one I could get working.

  • Open the registry editor. Press WindowsKey + R or search for the Run app. Then type regedit and hit Enter.
  • Naviate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
  • Double click on the key “UpperFilters”
  • Delete whatever value it has for it and then exit out of registry editor.
  • Go into the Device Manager (Control Panel) and uninstall the device.
  • Click “Search for New Hardware” and let it re-install the device.
