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

Anonymous

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.

    Thanks a lot!!

    Really glad to see someone finally did it.

    Microsoft should be ashamed that they were never able to solve the mystery!! 

    Now I'm finally able to update my apps dating back to nov 2013!!

    Hi,

    As I see neither wsreset.exe nor update package could solve this problem.

    take a look on my previous post, so you could easily make a tool that erase the cache completely, I think this could solve this issue permanently.

    Thanks for trying to help ;)

    Finally I found the best solution :D :D

    1. Problem is caused by:

    There are files in the store cache folder with a "too long and horrible names for the distination folder" that came with an inaccurate update, and these files simply makes the CPU turns in an infinity loop which couldn't stop tell you kill it manually !!

    1. make sure you have the same problem: (important step)

    >> kill the store & store broker now (end task)

    Go to:  "C:\Users<adminstrator_user_name>\AppData\Local\Packages\winstore_cw5n1h2txyewy\LocalState\Cache"

    & now >> select all files and folders in "cache" folder >> delete it !

    ===>> IF you have this problem there should be files couldn't be deleted in subfolders (0,1,2,...) 

    in my situation there were about 22 files in "0" folder that coudn't be deleted. what about u??

    So here's the big problem :P ... if you delete these every thing will be fine ,, it's much easier than we thought lool

    1. Do it simply & solve it:

    since you can't delete these files in regular way, even in safe mode, use this:

    • open the cmd as administrator (win+x then a)
    • copy and paste this syntax: >>>>del C:\Users\Mike\AppData\Local\Packages\winstore_cw5n1h2txyewy\LocalState\Cache\0<<<<< but don't forget to replace your user & the number of subfolder (Mike & 0)
    1. Traaaaaaaaaaaaaaaaaaaaaaaaaaaaaa it takes 0% now ;)

    >>> Typoll <<< you're the king man,, thank u so much,, To rename the folder was a really smart solution, but I think we had to delete these files finally :D

    I hope everyone will be satisfied !!
