Windows 10 Updates still not taking (Error 0x800700c1)

Steps 1-3 completed, on Step 4: no pop-up box with Defer upgrades option.

There was a drop-down box for "Notify to schedule restart" (this was selected) and another for "Automatic." I changed to Automatic and attempted to download and install upgrades again. No luck. I also followed the link to the Microsoft Update Catalog to
manually download and install Updates.
