I noticed recently that Windows 10 was using a high amount of CPU.
Checking Task Manager, could see this was coming from Runtime Broker.exe
A bit of Binging around and I found this solution posted in the Microsoft forums.
Click “Notification & actions”
Finally turn off “Show me tips about Windows”
Runtime Broker should immediately go back to normal.
I’m sure Microsoft will patch this soon, but this should get you by until then.
I haven’t had this problem since this post, but it did crop up again in Insider Preview Build 14291.rs1_release.160314-2254.
Repeating these steps, toggling the “Show me tips about Windows” on the off again seems to have fixed it.
I am, however, also seeing high WMI Provider Host cpu usage. It’s constant around 5% on 3 virtual CPUs.
