go to settings, select update security, windows update, scroll down to view update history, click on uninstall updates top left on the list, find KB4560960 select it and click uninstall.
I hope this helped!
Thank you, Tweedledee. However, when I get to Windows Update and scroll down to Microsoft Windows and choose KB4560960 , the 'uninstall' option disappears from 'Organize' at the top of the updates list. If I go to other KB updates the 'Organize' option re-appears, but not for KB4560960.
