Windows 10: after last update: windows shuts down but leaves error message in log

My wife's machine works fine.
And it shuts fine.
But after the last update KB3176938 there is a "not shut properly" message in the event viewer.

On my own machine there is a new wrinkle too: previously when I shut down I could bring the computer back by tapping on the keyboard but now I have to push the on/off buttom on the computer.

I am adding my machine into the mix because something has happened to the shutdown sequence with this new build. While it affects the two computers differently it is the same process that is at issue.

Thanks in advance for your help.

Shutdown

Since the last update of Windows 10 on my computer it will not shut down. I get the message about the task manager shutting down background files but it times out and returns to the logged in window. Is this a simple fix or what? I keep clicking the shut
down anyway to ignore the problem and shut down.

 

Windows 10 keeps restarting after 2 minutes

My computer also reboots after 2-5 minutes after displaying a blue screen. The blue screen cannot be captured and there is no error code. A message says computer is shutting down and capturing a log file. However, today it displayed additional message,
"Search for Kernaldata_inpage_" something something. Computer shut down before I could write down entire name. I searched entire OS drive but could not find a match on partial name. I looked in Windows Log and Temp files. There is a Memory Dump file that
matches the latest shut down time. Where do I find this error file????? Perhaps that info will provide an error code.

Machine will not stay up long enough to switch back to Windows 8.1. Please respond!

 

I have KB3176938 installed and have not noticed any changes in the shutdown of my system(s).

Are you sure that you were not previously putting your system to SLEEP vs SHUTDOWN. As you describe it now, that is what should happen. When I put either of my W10 systems asleep, a single key stroke will wake them up.

 

that is possible.
that the update changed the power settings on both machines.
my wife's machine is on balanced and mine is on high performance.
what setting do i need to change to revert to the earlier situation (on mine)?

thanks.
