Windows 10: Runtime broker and Windows shell Experience Host high cpu usage

Solutions I already tried:

* HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TimeBroker Changing Start into 4

* Removed the slideshow notification

* Closed all my personal tray apps

* Performed an offline scan using Windows defender

* Performed a normal scan using malwarebytes and windows defender

* Disabled unknown services from the msoncfig

I do believe that this problem is related to a program I'm using but i can't figure out which one

:)

 

Runtime Broker high CPU usage

I am running Windows 10 Pro (Version 1511 for x64, update KB3149135) and had problems with Runtime Broker.exe using anywhere from 30% to 90% of my CPU. Disabling hints and removing OneDrive did not help me, but I found the advice in this article helpful.
I used the PowerShell commands as admin and uninstalled all of the suggested apps save the windows store. Not sure which one finally did it but I don't really care as long as I'm not running at 50 degrees Celsius constantly.

Runtime Broker high CPU usage

I found that if I just don't minimize the groove music app then runtime broker doesn't eat my cpu. So temporarily I don't minimize the groove music but it's very ridiculous that minimizing the app cause cpu usage by runtime broker. I hope microsoft fix
this issue with grove music.
