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 cant believe I had the same type of problem with that "tiworker.exe" program or file or whatever. I just bought a Toshiba satellite C855D-S5320 and instead of getting better performance I got a load of trouble shooting duties for my Saturday. I don't know if its a Toshiba problem or a Windows problem but gees, come on seriously? The fact that I have to be doing investigations, trouble shooting, tracking down rouge programs is infuriating and so disappointing. Then I read the "tech" solution to the problem and its more of the same scanning and probing and downloading another "diagnostic" program on top of Toshiba's and Microsoft and Norton's! It's a NEW COMPUTER!!!! Why is this causing such a problem for the system to handle. I noticed that it was taking up all the resources and massively slowing down the CPU until I finally just rebooted the whole thing. Its recorded in the logs as a potential compatibility problem.

    Yeah, It's not a Toshiba problem, it's a Windows 8 problem. I'm having this problem on my HP Pavillion G7, It's really annoying that the recommended service, "Microsoft Security Essentials" is only for Windows 7. It's also annoying that tiworker.exe is a Windows task not a virus, and they recommend a virus scanner.

    The link to the troubleshooter helped, but only a little.  It confirmed that it could not fix the failure to update Windows.  Manual install does not work either.

    Agree, I just finished a fresh install also. I will not be updating to Windows 8.1. I retired that computer for now, It was too expensive to let Windows 8 eventually destroy it. I am using another computer with Windows 7 on it and considering installing Windows 7 on the computer I retired.

    As I noticed the date of your post, I could not help but to sign in and declare the same thing as being described in the majority of the other posts, is also happening to me.

    I am finding;

    that all the virus scanners in the universe,

    all the update helpers as well, and also, Microsoft Windows in General,

    are not helping one little bit.

    Nay, not even a fraction, of one little bit.

    I shall never ever understand the logic in a business building itself up,

    and then destroying the very thing that made it become so big.

    I just completed a fresh install.

    Windows 8 is taking up 19 Gigabytes of space on my hard drive.

    Why...?

    And, Microsoft keeps nagging me to, "upgrade"(?) to Windows 8.1...

    Uh huh. From my experience with Windows 8.1, I am allowed even less control of My pc data...

    Keywords being, My PC.

    100% cpu by TiWorker.exe is ridiculous.

    Cannot help but wonder why it does not seem to be being addressed by Microsoft.

    Not tomorrow, not next week or next month,

    As Now, would be acceptable...
