not sure if this will fix your problems, but when I upgraded to Windows 10 I needed to update my graphics card, and switched from AMD to NVidia - which meant I was ken to have a clean start.
I found a utility Display Driver Uninstaller (DDU), which clears out all the dll's, registry entries, etc of your display driver ready for a clean install of the new one.
One option would be to download the latest driver and save it in a known location
Then delete your existing driver using DDU
Then install the latest version.
Windows update should then sort itself out, as you will have the latest driver.
Of course, if you are happy you have the latest driver installed anyway, then you can simply ignore the failed update - if you do a manual scan for updates it will list all it thinks you need, and you can right click and tell windows not to apply that update.
