Service Host: Web Account Manager using 70+% of CPU

I noticed that the fan on my laptop (Thinkpad Yoga X1) running Windows 10 was running at full speed, which was draining the battery quickly.  At the same time noticed a sharp drop off in performance on the machine.  (I was waiting for the applications to catch up with the keystrokes, etc.)

I the looked at the task manager and noticed a process called Service Host:Web Account Manager using most of the CPU capacity.  See below. 

If I stop the process, the fan slows down, the applications and  internet browser return to their normal self.  But, when I restart the machine, this Web Account Manager returns along with the degraded performance.  Do I need this process, and if not, can I disable it?  Or, it this situation a result of something else going on.  (This started back after a recent update I did.  I tried to restore, but it wasn't successful.) 

Any help or suggestions are appreciated.

Answer
By shut off, I mean in Services.msc to choose the service to Disable and Turn Off.
