Starting several weeks ago (January 2014) the task Windows Store Broker (wshost.exe) starts randomly and quickly climbs up to 50-60% CPU usage - even if no "Metro" apps are running and I haven't opened the Windows Store. I can end the task in the Task Manager yet it starts again within minutes and begins using 50%of my CPU again. (See screenshot).
Full anti-virus scan reveals no problems.
Resetting the Windows Store (wsreset.exe) doesn't solve the issue.
I searched the Windows\WinSxS directory and found wshost.exe in 3 places. One of them was updated January 17, 2014. My guess is that this update caused the problem.
Anyone else having the same issue?
Anyone found a solution?
Is Microsoft aware of the issue and working on a solution?
My only resort for now is to disable the Windows Store via a registry entry to avoid my laptop continually overheating due to extremely high CPU usage.
I appreciate any help.
