So far, the Nvidia update has not crashed but it will take a couple of days to know for sure.
I now have a second system which just updated today and lost the entire desktop and only showed Windows Mail. The Mail app would not close but would minimize. Of course, when it minimized, since there was no taskbar I could not see that icon or anything else, the desktop was completely blank.
Two systems with problems, it doesn't look good for a new build....
