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 think the problem is what I've also been running into with Windows 10 (beta, yes, I know).....  some system process that is on that may be good for a novice is left on for everyone and is meant to run as a background process, yet it runs with Normal priority.

    Windows Update shouldn't run as normal priority.  

    As a programmer, I learned that the best way to get your programs running efficiently was to always have a slow PC around.  A slow PC will always make sluggish performance more apparent.

    When installing this on an Inspiron Duo 1090, I found both this and the Messenger issue which keeps LiveComm.exe running at high CPU usage.  I always clean out the SoftwareDistribution folder under c:\windows but you periodically have these processes running that don't benefit me.  Search is always running in the background and yet i rarely search for something.  For me, I'd rather wait 15 seconds while it looks for something than to slow down everything else I have.  Honestly, the only thing I really use that indexing for is for the Music App which I'm not using until you get that OneDrive integration turned on.

    So, I turned off that piece, added a firewall entry to block the LiveComm.exe from hitting the messenger servers there, and now I set Windows Update to check for updates but to not try to install them.  

    So far so good.  I just wish I could schedule these checks to only do these types of things after hours instead of while I'm actively working.  If I have to wait 15 seconds while searching which I rarely do, then I'll do that.  No problem with that.

    Still love Windows 8 and 10 though.
