On a system that had been quieted, no new attempts to communicate online have been detected after these updates (I got KB3139907 and KB3140743 together).
For what it’s worth, Microsoft actually HAS provided all people need to take control over WHEN and WHETHER updates are applied to Windows 10.
Between the Microsoft Show or Hide Updates tool (KB3073930) both showing the list of available updates, and the abilities to reconfigure local policy or even go so far as to Disable the Windows Update service, any user willing to follow a small procedure can be in complete control.
I’d wager most folks don’t realize the Microsoft Show or Hide Updates tool can be employed as a “what’s available”.
Of course, they could just come here, or go to Microsofts “Windows Update History” log to see if something new worth considering has arrived. This blog is how I knew to look for the 10586.122 update…
