Windows Store Broker problem: very high CPU usage

I think I am a bit of an omelette too, I have been in the same boat as everybody on this since January and yes I think that MS are very slow to respond on this as it is affecting a lot of users. Here is my problem trying to find the path detailed in Typoll's post please see the screenshot and tell where I am going wrong

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.

I too am one of the Windows 8.1 users who all of a sudden cannot run STORE. The initial screen comes up with the rolling 'beads' and thats about it. I dont use STORE that much but on 3.23 I wanted to check for app updates by first going to the STORE.

I have had this Dell AMD A8 laptop since Dec. and things were fine till this happened. As with others, I noticed both STORE and STORE Broker running high CPU >45%. Have to close the app. Had the Answer Desk on the pc for couple of hours with no resolution. They ran the usual WSRESET and SCANOW or whatever its called. They also ran DISM(not sure) and that said things were repaired but it lied.

Ran APP Trouble shooter and it said to upgrade Video drivers. Probably because the settings for apps says NOT to auto download new drivers. I think this pc is set this way from Dell because drivers come from them.

I have a Radeon HD 8510G video adapter - 

For the Radeon 8510G HD driver – 13.250.31.0 – this level doesnt even show up on AMD sites for the Radeon adapter. 

Have to call back to Answer Desk with my Case number when I have a couple of hours or more to watch them 'resolve' my problem.

Dont understand why one cannot reinstall the STORE component of WIN 8.

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

PS

This really works for a lot of people. There is a file in the Cache folder which is too long to delete. We think that is the problem where on process of Store creates this file then another process tries to delete it. This creates a loop which ramps CPU and causes Store to fail.

Renaming the folder and creating a fresh version just simply works.

Hope this helps.
