First, restart your machine at least three times. I don’t know why, but rebooting numerous times sometimes shakes out the gremlins. Second, try to uninstall the patch and see if the problem goes away. Click Start > Settings > Update & security > Advanced options > View your update history > Uninstall updates. With a bit of luck, the aberrant update will appear at the top of the Microsoft Windows update list, as you can see in the screenshot. Double-click on the update and when Windows asks, “Are you sure you want to uninstall this update?” reply Yes. Windows will take a while -- maybe a long while -- to reboot, and when it comes back, you should be retreated to the previous (presumably functional) version of Win10.
