Windows 10: Reliability history indicates that Windows has periodic unexpected shutdowns. However, I...

I recently put together a computer earlier this year. Everything seems to be working just fine. When I shutdown my computer, everything seems normal. When I start it up, and look at the reliability history, Windows sometimes records an unexpected shutdown from the previous shutdown. I first noticed the issue when my computer would go to sleep. When I would return to my computer, it would seem like it restarted. This didn't always happen. It seems somewhat random. All my applications would be closed and it was as if Windows was starting up for the first time again. I disabled sleep on my PC

Unexpected Shutdowns on W10 v 1607 build 14393.187

I've seen 3 unexpected shutdowns in the last 5 days since I installed W10 v 1607 build 14393.187. No additional information is available in Reliability History. Is anyone else seeing this issue? Any suggestion from MS?

 

Unexpected Shutdown

Hi

Please see response to your questions below

• Did you make any changes on the computer prior to this issue?
  

No changes other than about a month ago reinstalling W10.

• What troubleshooting steps have you done so far?

Other than checking updates have successfully installed, none as not sure approach to take.

• What was the exact error code/message you have received?

No error code or message received. On the first occasion I was looking at outlook and without any warning the PC shutdown. It was almost as if it was a desktop (it is a laptop) and the power stopped. The laptop was plugged into the mains and in addition
the battery had a full a full charge.

On restarting the laptop no error message came up and I only noted a small difference in boot up, that for a short period a blue screen was displayed (not normally seen on boot up) and then the start screen appeared for me to log in.

As mentioned previously the only reference to this is from the log which in the summary states that there was an unexpected shutdown.
