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 am having the same problem with my recently purchased HP but at 100 percent usage.  This sucks.

    PLEASE SOMEONE AT MICROSOFT FIX THIS ISSUE.... I just bought a brand new laptop and I cant even create a word document with this thing taking up all my resources. I make one change to the document and I have to wait 3 mins for it to respond... With a new laptop? are you kidding? Im about to break out my old laptop and do my work on that one, at least it wont take me a year to finish my document. What a waste of money.... Shouldn't this have been caught in the testing phase before releasing this new software? I should have bought a MAC.

    Sincerely,

    Broke and Frustrated

    Also hitting this issue on new Windows 8 Enterprise Edition.  The Servicing Stack update didn't not help but what did help was to:

    1. Set system to never check for updates(probably not needed as only when I did step 2 did the issue go away).
    2. Disabled the Windows Update Service (in services.msc)

    Rebooted pc and so far the tiworker.exe process no longer appears in Task Manager.

    I can live without windows updates for the moment until MS release a hotfix that fixes the problem.

    I don't know if this matters, but when I first clean installed Windows 8 Pro it was a nightmare with TiWorker.  It doesn't happen much now -  and when it does happen inevitably it is an update for Office 2013.  Most of these posts are for new machines (myself included as I ended up here right after I installed and patched Windows 8 Pro.)  Just passing along...
