After Update No Task Bar - No Settings

Windows 10 updated itself two days ago. Since then, there are no icons on the task bar. Moving the mouse over the task bar produces gray squares where the icons should be. There are six squares for the six programs I normally access there. Right-clicking on a gray square provides access to the program. But the icon is not visible. Also, clicking on the Settings produces no result whatsoever. Right clicking allows pinning to start or task bar, neither of which happens. And, the time/date from the lower right corner is missing. Double clicking on the missing spot raises up a calendar with the time.
