Cumulative Update for Windows 10 Version 1511 KB3140742

One thing that I have noticed with Win 10, 1511 (10586.104), when I power up and check with Windows Explorer, my Mapped Drives (NAS) show with a Red X on them. When I click on them though, they are working and the Red X goes away. Same behavior on my Win 7 Pro machines also.
With my Insider Preview machines (Desktop, currently 14257.1000), that behavior does not happen, in other words, when I boot up and use Windows Explorer to look, ALL of my NAS mapped drives show up normally.
I used the manual download and got the 64 bit patch KB3140742 and applied it to one of my Win10 Desktops and my Laptop (1511 10586.112) and the NAS drives now show correctly after navigating to them (several re-boots to insure it sticks). This is the first time that I have been without RED X's on my NAS drives since Forever!
Someone at MS seems to have done some work and actually got the mapped NAS drive functionality working correctly (better)!!!
Has anyone else noticed this improvement in behavior?
Opps! Spoke too soon, this morning after booting up the laptop, the mapped NAS drives are still showing the Red X's, then checking the Desktop, it too is Red X'd!!
The insider Preview (upgraded to 14267) are still showing all OK!
