Microsoft minesweeper, solitaire, calculator stopped working

Several Microsoft products recently quit working.  They start, but just put up a blank screen.  Examples:

Calculator; Minesweeper; Solitaire & Casual Games

My Office products are working.

Running Windows 10.  Browser is Firefox (up to date).  Changes:  Just bought a Norton "Driver Update" thingie, and it updated a number of my drivers.  Other notable:  I'm supposed to have "Anti Track".  However, I have a reminder that pops up from time to time that says it's not running or that I don't have it set up/implemented.  I'm baffled.
