To fix this registry related Windows device driver error (Code 19), follow the steps as below :

  • Navigate to Start -> Run and type "REGEDIT" and click "OK" to launch the Windows Registry Editor.

  • Now from the faulty device driver properties page, make note of the "Device class GUID" as shown below.
  • Device GUID
  • Navigate to HKEY_LOCAL_MACHINE -> System -> CurrentControlSet -> Control -> Class key inside windows registry editor and then click the "GUID" noted down in step above, you will see something like below - select the "UpperFilters" and "LowerFilters" keys and delete them.

Can I suggest a simpler solution (which worked for my kids comp(XP SP3)? Download " - Windows Repair (All in One) v1.5.2". Unpack( u dont have to install it). Go to the 5th stage & ONLY CLICK THE REPAIR cd/dvd Drive option. once it`s done, re-start if asked to. & it worked for us. IF it works for u, good, else try the complicated options.
{I can`t recommend the other repair options with tweaking, coz like all the reg cleaner-type software, it can create complications). Best o luck.

Need Help

I don't have no ''UpperFilters'' or "LowerFilters" there. Now do i have to throw my pc out of the window? (I live on a 5th floor apartment)

Thanks, this even worked in Boot Camp--although there was only one filter to delete. Still worked though!

Hi Guys,
most of the info on the web about how to solve this problem revolves around the CD/DVD ROM drive. Any advice for solving this same problem with the Lenovo g560 built-in Webcam (Lenovo easy camera)??

What i've tried thus far:
Update Drivers - Drivers up to date
Uninstall/reinstall webcam
uninstall/reinstall usb ports

nothing works thus far.

Please help!


This worked for my usb driver! Had to use only ps2 keyboard to fix... Thank you!!!

I don't have no ''UpperFilters'' or "LowerFilters" there.
Is there something else that I can do. I have a Dell Inspiron windows 7 64bit
