Windows Store Broker problem: very high CPU usage

Anonymous

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.

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,

Ron

It may be necessary to show both Hidden, and System Files, and also to uncheck "Hide known file types" in Control Panel/ Folder Options/ View, to navigate to the mentioned AppData location.

Select Options.

Folder options should appear:

Click the View tab then select "Show hidden files, folders and drives"

Select OK.

Proceed to Appdata

    Fix Store App in Windows 8.1

    http://blogs.msdn.com/b/notime/archive/2013/10/21/10458031.aspx

    •Sometimes, after upgrading to Windows 8.1, the Store App may not start.

    •It might still show the number of available updates on the Live Tile.

    •Starting the app may show a progress ring but it may not finish loading.

    •To fix this, run the following in a Command Window (CMD) to re-register the Store App:

    powershell -ExecutionPolicy Unrestricted Add-AppxPackage -DisableDevelopmentMode -Register $Env:SystemRoot\WinStore\AppxManifest.xml

    Do you dabble with Registry Cleaners or "Boosters"?  They often cause weird problems.

    For me this coincides with the windows store not loading. I just get that spinning dots thing. It is really quite frustrating. Tried a couple things like running wsreset, re registering the store, checking firewall settings, and i refuse to refresh this pc. So i'm just kind of stuck like you.. On the upside there have been more posts recently about this problem. I encountered the issue after installing a good amount of updates via windows update. Good luck guy
