Windows 10: How do I stop windows 10 update 1079

How old is Norton Security Suite? Is it part of a package from an Internet Service Provider? Has it been upgraded? Updated?

In my case, I didn't get upgraded from 1607 to 1709 until coincidentally my Norton 360 got upgraded.

Strangely, and possibly off-topic, I also had an error 0x80072efd 'early' in the upgrade process from 1607 to 1709. I had left the upgrade process unattended early because I knew the download would take a while. When I returned, the error message in a window was there to greet me. During that time, the machine was still processing the upgrade 'intensely' in CPU and disk activity. ??? When CPU activity quieted down to < 10%, I made active the Windows Update service window and clicked 'Restart'. The upgrade process then continued for several more hours after that, as if the error message was but a passing meteor.

I have Norton provided by comcast. It has been updated and is current to the best of my knowledge,

Norton 360 was upgraded to 22.12.0.103 last week.

Prior to the upgrade(s), both Norton and Windows 10, Windows Defender did not exist in my TaskManager. After the upgrade(s), Windows Defender coexists with Norton in TaskManager.

There was the warning often heard that one shouldn't use two separate security programs that perform the same functions. Apparently, Norton has relinquished some function back to Microsoft.
