Why does Store Broker (wshost.exe) keep killing my CPU?

I've got a new Windows 8 machine and, for some reason, the Store Broker keeps pegging my CPU. It seems to pop up every time I do anything with the Windows Store (makes sense) or use some Metro apps (also makes sense). However, for some reason, this process takes up 33% of my CPU and never lets go of it once it starts. This causes the machine to get hot which causes the fan to come on and the combination drastically reduces my battery life (from 11hrs to 3).

Aside from frequently checking for and killing this app, is there anything else I can do about this? Is anyone else having this problem? Is it a misconfiguration on my end? I'm running this on a new Surface Pro 2.

Thanks!

I SOLVED this. At least for myself. It's been a 3-day journey. Argh!

The upshot is this:

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

I have been at this for days. I've read every article and post everywhere. I have updated graphics drivers, set date and time, run wsreset, sfc /scannnow, created new user account (store did work for new account), app troubleshooter, etc, etc, etc...

Today I just started digging around and looking at dates. I don't have log files to back this up but I believe I broke Store with CCleaner. I'm not sure exactly when the Store broke so this is a best guess but it makes some sense since Ccleaner does clean Store cache.

I also recently installed Tor Browser but my gut is that that was totally unrelated.

I might create a sandbox user and try to break Store with Ccleaner to confirm. But honestly I am tired of this little adventure.

    EdStudio, I'm pretty sure you haven't tried disabling the Windows Store with the reg fix located on this page: http://www.eightforums.com/tutorials/5804-store-enable-disable-windows-8-a.html

    See page 6 of this thread for further info. So far, everybody who's tried it has (temporarily) solved the problem until a real windows update patch comes along.  Good luck!

    Just wanted to chime in here to say I am having the same issues and have tried all advice previous.

    This is a newly built PC with a clean install of 8<8.1. I am also receiving a constant never ending spinning dot wheel when trying to view the "your apps" section on the store which didn't happen before a previous update.

    Will gather log files asap.
