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 just bought a Lenovo Windows 8 Pc. Brand new.. And I try using this thing for school I can't even use word without other programs.. Microsoft Safety Scanner does nothing for me.. and the Tieworker takes like 70% of my CPU. This makes me frustrated. I use my money for a product for SCHOOL and it doesn't even work without "not responding" programs.. I am a Windows fan I have a 360 and a Xbox one. I just got this PC and it's not even working. I am the only one in my house with a Windows computer everyone has a mac because of this issue. I contacted support they told me to go buy another 100$ ram! When this one was the same thing...... I am very frustrated right now...

    Thanx for the information TiWorker.exe no longer running on my machine.

    Do you have anything that will help block or delete GWX.exe, I won't update this machine to 10 it's to old but would like to stop upgrade notifications.
