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.

    Ran the command line instruction before I went to bed and all was well the next morning. Memory hog TiWorker.exe was gone.

    The purpose of a computer is to automate tasks allowing the user increased time savings. This TiWorker nonsense hangs up computers making them worthless. Worse, users are expected to fix it themselves which is more nonsense. I am finding Microsoft is trying to trap users into being unwilling advertising cash cows for Microsoft which explains most of the complaints with their software.

    Under an Administrator account, do the following.

    Click the Search (magnifying glass) icon in the lower left.

    Type in:

    CMD

    but don't press enter.

    Right-click the "Command Prompt" icon above and select "Run as Administrator."  A DOS window will appear.

    Select the DOS window and type into it the following:

    DISM /online /cleanup-image /RestoreHealth

    Now wait about an hour.  When the command is done, reboot your computer.

    Lastly, **** you Microsoft for making this problem impossible for anyone but a computer expert to solve.
