>I just mentioned it because the Windows updates happened around this time and you might get the wrong idea of the cause or solution of the problem. But if you applied the updates yourself at a known time you can rule that out.

Correct

>I don't know of any further update today. If you're like me you wouldn't let the updates install automatically and potentially restart the machine(s), you'd allow download and then notification. So you'd be notified if there was any new update today.

Correct

>You can always check the Update History on both machines to see if anything new was somehow installed.

The ones there have been done by me.
