TiWorker 50% of CPU and Updating doesn't work in any way

I just purchased a copy of Win 8 Pro and I see that there is a process eating up 50% of my CPU.

It's called 'Windows module installer worker'/TiWorker.exe.

I've tried to run some updates in the hope that it will fix it (although why aren't the updates included in the Win 8 version I just downloaded today, I don't know). I cannot update anything.

I am very frustrated as I've wasted 6+ hours of my weekend on this and while I was enthusiastic on switching to Win 8, it turns out it's such a complete waste of time. Incredible and if it wouldn't be midnight, I would be half way through installing Win 7 right now.

I had the same problem on my Toshiba Z30t running Windows 8.1 64-bit Pro. Soon after unboxing it, I ran Windows Update, and after 30 or so updates were downloaded and installed, TiWorker.exe reared its head and pretty much took over my laptop.

After a bunch of googling over the past couple days, I ended up following the advice from this bit-tech column about Microsoft's botched update of the servicing stack.

Opening command line in Administrator mode, I executed the Deployment Image Servicing and Management (DISM) command with the following switches:

DISM /online /cleanup-image /restorehealth

And after a reboot, no more TiWorker.exe hogging my Z30t, even when I've left it idle.

    I haven't even had my laptop for a week and it's coming up with this tiworker.exe thing !!  Very disappointing to read all about here.  $400 and I'm sitting here frustrated!

    Windows 8; I am very frustrated with this version of Windows. It should not be continued to be installed on new computers!!!!! I have tried the virus thing...the supposed update fix is already installed on my computer and Tiworker.exe is still using high CPU, up to 99%. I have been trouble shooting for 2 days only to discover THIS CANNOT BE FIXED!!!!!!! Seriously Microsoft, fix it or take it off the market!!! Seriously considering a Mac for my next computer which obviously is going to have to be soon!!!

    Okay. It's now June 2014, OVER A YEAR LATER, and I have the same problem.

    Does Microsoft actually have any SOLUTION to this?

    "Run a scanner" isn't a solution. It's avoiding addressing what is obviously an ongoing problem.
