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.
