  • "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. To fix this problem you should uninstall and then reinstall the hardware device. (Code 19)"




For some unknown and strange reasons my "Windows 7" installation stopped recognizing my DVD drive and "Windows Device Manager" showed an exclamation icon next to the DVD/CD-ROM drive, on further opening the device properties page the error shown is :​
"Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)"
​
The error signifies that an registry error has occurred with the device in question, you can find a working solution as demonstrated below.​
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.
  • Once started click "File" in menu bar and then Click "Export" from the drop down menu, now save the registry backup (All) just in-case things go bad.
  • Now from the faulty device driver properties page, make note of the "Device class GUID" as shown below.
    ​
  • 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.

Fixing Compaq Presario Laptop Not Recognizing Microphone And Headphones In Windows XPMy friends Compaq Presario C770TU laptop started having issues with external headphones and microphone being not recognized by Windows XP, contacting HP support regarding the problem resulted in the response below with links to download Windows XP drivers "I would like to share

that the above mentioned notebook has not been certified on XP and hence not supported. Hence we would not encourage the use of NON-Certified drivers on the product as it may lead to degraded performance and damage the product in some instances which would then not be covered under standard warranty.However if you would like to pursue Win XP installation on the product, I have captured the links below wherein the nearest compatible drivers are available."​

First of all its very bad on HP's part to not support one of the world's most successful and widely used operating system, secondly the audio driver they sent links to download does not solved the problem, I had to try different Conexant audio drivers to finally find a working one , if you are having similar issues with your HP laptops follow the instructions ahead to get your headsets working on Windows XP.Problem : Unable to use internal or external microphone, laptop speakers won't mute while external headphones are plugged in, installing HP's sound driver (sp34386) produces error message: "Driver Installation Failed: Could not find the MEDIA device for this driver" on HP Compaq Presario Laptop running Windows XP.Solution : Download and install correct drivers as follows.​
  1. Download and install Microsoft UAA Audio Driver, reboot your laptop after install.
  2. Download and save Conexant SmartAudio 221 audio driver.
  3. Unzip the downloaded driver and run setup, if error occurs use device manager as instructed next.
  4. Right-click My Computer and select Manage.
  5. Click Device Manager from Computer Management screen and navigate to "Sound, video and game controllers", right-click Conexant High Definition Audio or Audio Device on HD entry and select driver update.
  6. Continue with the wizard selecting "No To Connect - > Install from a list or specific location -> Don't Search, I will choose the driver to install".
  7. Click Have Disk button.
  8. Browse for the folder downloaded and extracted in Step 2 above and select the driver file WiSVHe5.inf.
  9. Ignore any warnings and continue installation, your problem should be fixed now.
