Up and running with 26080, no problems so far. I will comment that when I first did the Windows Update approx. 1.75 hrs after CK's post, it came back and said "You're up to date"! That was a scare, but I clicked on a few things, got the ISO that I didn't want, but then Windows Update found and installed 26080 so all's well that ends well.
I'll just comment that I think my PC and my wife are in a contest so see which can do the most things I don't understand at times! 😁
