I also have this problem with my Windows 10 laptop.
In my "View Your Update History" section of "Settings", I see an entry stating that:
"Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3185614) Failed to install on 9/14/2016".
If anyone either on this site or at Microsoft Inc. could help me solve this problem, I'd greatly appreciate that.
Thanks!
