HL-DT-ST DVD+-RW GH50N DVD Drive not working on Windows 7 Code 19

Sometime very recently my Dell T3500 desktop lost the ability to access it's CD/ DVD Burner drive. I don't know exactly how it occurred but I noticed it today and managed to find a workaround to fix it. (The only things I've installed today were a Windows Update for Security Essentials and two Apple Updates for Safari and iTunes / Quicktime.)

My T3500 has a DVD Burner with the model number: HL-DT-ST DVD+-RW GH50N. I located this information in Device Manager. When I tried letting Windows 7 update the driver it gave me a Code 19 error message which means the driver information in the registry is missing or damaged. To fix this problem you need to delete the registry key and uninstall the driver.

Here's what I did to fix it:
  1. Reboot your computer and put it into safe mode
  2. Open the registry (using regedit)
  3. Navigate to the registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
  4. Try deleting the entire registry entry. Trying to delete the entry didn't work for me so I went through the entire entry and deleted the individual attributes, except for the (Default) attribute at the top. It wouldn't let me.
  5. Then go to Device Manager and uninstall the driver for HL-DT-ST DVD+-RW GH50N
  6. Reboot your computer normally
  7. When you log into Windows it will detect a new CD ROM device and reinstall the normal CD driver
  8. Go to Computer and you should see your DVD Drive
  9. NOTE: When I went back to Device Manager it still doesn't recognize it as a DVD / CD drive but there it is working. See below.

Your DVD Burner should now work, albeit this isn't a permanent solution since Windows doesn't fully recognize the device as a CD ROM drive. Hopefully whoever broke this will fix it.
