Windows 10: Mobile Plans Background Task Host Hogs CPU -- and My Computer Is Not Mobile

This morning, after using Task Manager to make SystemInterrupts behave like a cockroach does when the light is turned on, I found something called "Mobile Plans Background Task Host" hogging my CPU.
Note that the only thing searching for "Mobile Plans Background Task Host" brought up had no "Mobile Plans" in it.
My computer is a desktop machine, not a mobile phone ("Mobile Plans Background" brought up a lot of links about Mobile Phone Plans). It really should not be running this sort of thing at all.

Background Task Host Excessive CPU Usage

Tried the two steps like you said.

1. On Safe Mode start, CPU was at 0%. No issues.

2. Then on Clean Boot, the same problem was repeated. With RunTIme Broker and From Microsoft Background Task Host taking up atleast 50% CPU resources.

Now I have it back to Normal mode start up. And yes, the problem still persists !

Did this help in anyway..? Please do assist me further.

 

Cortana background task host resource hogging


Good. For amusement (?) this is what happens when, with no music catalogued by Groove, I say
'Hey Cortana, play some music'
'All right, playing your music'

Hi, just a quick thought from your 3rd screenshot (thanks for providing these)..
This suggests to me you have an extensive music collection being catalogued (or whatever it is Groove does with music files).

I suggest you disable music cataloguing and see what effect that has.




I've never let that happen so I can't comment from personal experience. (However I can say that if you say
Hey, Cortana, play some music
with nothing catalogued, the response demonstrates a certain lack of thought by MS!)


The first screenshot requires technical analysis to discover what servicehost.exe is doing.
