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.
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
Kill Store and Store Broker from task list.
Rename the Cache folder to CacheOld at:
C:\Users(Your User Account)\AppData\Local\Packages\WinStore_cw5n1h2txyewy\LocalState
(Your WinStore_gobblygook might be a different bunch of gobbblygook)
Create an empty folder called Cache.
Solved! For me anyway.
Enjoy,

These are the 3 WSHost.exe files I have on my Windows 8.1 64-bit machine. The one in C:\Windows\WinStore is the most important. Do you have a copy of that one in that location?

Still waiting answers.
All gone quiet on this issue.
Maybe no one know the answers. Very embarrassing. Someone must have an idea about Microsoft windows...at Microsoft.
