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,

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.

Right, this problem needs to be sorted out. Microsoft are obously aware of this problem, so why dont they sort it out?? I have to kill this every time i swich my computer on as it uses 30%+ of my cpu usage. It is overheating my laptop which can damage parts, and who would be blamed if it did?? me of course. after I have restarted my laptop I will show some screenshots of temputures and cpu usage.

I have had the same issue with the store broker on an acer revo RL 70.

30-50 % cup usage at all time.

The wsreset.exe works as an sulution for me, and the system is working normaly now.
