A Code 10 error is generated when Device Manager can't start the hardware device, a situation usually caused by outdated or corrupted driver.  In other words, a Code 10 error can sometimes be a very generic message indicating some kind of unspecified driver or hardware problem.


How to Fix a Code 10 Error

1. There is always the chance that the error Code 10 you're seeing on a device was caused by some temporary problem in Device Manager or with the hardware. If so, a reboot might fix the Code 10 error.

2. Did you install a device or make a change in Device Manager just before the Code 10 error appeared? If so, it's possible that the change you made caused the Code 10 error. Undo the change if you can, restart your PC, and then check again for the Code 10 error.

3. Removing or re-configuring the newly installed device.

4. Rolling back the driver to a version prior to your update.

5. Using System Restore to undo recent Device Manager related changes.

6. Reinstall the driver for the device. Uninstalling and then reinstalling the driver for the device is a likely solution to a Code 10 error.

7. Update the driver for the device. It's also very possible that installing the latest driver for the device could correct the Code 10 error, even if these driver were previously functional.

8. Install the latest Windows service pack. Microsoft often releases service packs and other patches for Windows, one of which might contain a fix for the Code 10 error.

9. Delete the UpperFilters and LowerFilters values in the registry. Two particular values in the Windows Registry could be corrupted, causing the Code 10 error. While this isn't a very common solution to a Code 10 issue, it is for many other Device Manager error codes.

Removing the UpperFilters and LowerFilters values in the Windows Registry is easy.

1. Press the How to Fix Code 10 Error in Device Manager 7W6b39o keys to open Run box, then type regedit into Run box and click OK button.  This will open Registry Editor.

2. Expand the "folders" until you reach the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class registry key.

3. Click on the > or + icon next to the Class key to expand it. You should see a long list of subkeys open up under Class that look something like this: {4D36E965-E325-11CE-BFC1-08002BE10318}.

    Note
Each 32-digit subkey is unique and corresponds to a particular type, or class, of hardware in Device Manager.


4. Determine the Correct Class GUID for the Hardware Device. Using this list, find the correct Class GUID corresponding to the type of hardware that you're seeing the Device Manager error code for. For example, let's say your DVD drive is showing a Code 10 error in Device Manager. According to the list above, the GUID for CD/DVD devices is 4D36E965-E325-11CE-BFC1-08002BE10318.

Once you know this GUID, you can continue to Step 5.

5. Click the registry subkey corresponding to the device's Class GUID that you determined in the last step.

6. In the results that appear on the window on the right, locate the UpperFilters and LowerFilters values.

    Note
If you don't see either registry values listed, this solution isn't for you.


7. Right-click on UpperFilters and choose Delete.

8. Repeat Step 7 with the LowerFilters value.

9. Close Registry Editor.

10. Restart your computer.

11. Check to see if deleting the UpperFilters and LowerFilters registry values solved your problem.


A problem with the device itself might be causing the Code 10 error so you might need to replace the hardware.
