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.

    Pretty bad that Microsoft never got back to us on this. Before the posted Fix I had to re install the OS because there were some apps I wanted to use on my PC. Sigh...

    Warning!   Applications such as netflix, Sky tv, Youtube etc use a huge amount of cpu even it look like they are not running. best way to solve this issue is to:

    Uninstall apps that have use a video service.

    Re-install one buy one testing each after you re-install (play a video then close the app check cpu usage).

    Greetings

    At last some said what I wanted to say, thank you "cath8r", we are treated here in this Microsoft Community as a Rookies how are using the Computer for the first time in their life. But they should know that most of the time professional people ask questions here because they want to help themselves and other people to get over what ever obstacles they are facing in Microsoft Products.

    Even the solution provided here which have more than 70 agreement of logged in people and a lot reading this thread, does not really fix the problem but it is the only override solution.

    But what i'm facing here (and could be others also):

    1. If I regularly entered the STORE and download anything from it, the problem raised up again and the again also I fix it with Mr. TypoII solution, thanks to him.
    2. As a side effect: The PC will be unable to enter Hibernation mode occasionally.

    I usually don't shutdown my PC, I just made the power setting to Hibernate after 30 minutes of inactivity, so when this problem started to rise up my PC never been in Hibernation state, and after the fix some time it will do and some time it is not.

    This month was so devastating to me with most of Microsoft services and products, I'm just hoping not to hear someday someone saying "Abandon Ship"!!

    Best Regards
