Hi John Davies,
Does the problem go away after uninstalling the problem update?
Regarding your information, it seems that your camera drivers are not compatible with the latest patch.
Currently, there's no announcement about updating Windows could affect camera functional, however if your camera worked perfectly before the update, you may try uninstalling it following this article: How to uninstall a Windows Update.
If your camera does work after uninstalling the problem update, please pause Windows Update and wait for the patch that fix the problem.
If you have any updated information, please feel free to let me know.
