TiWorker 50% of CPU and Updating doesn't work in any way

Anonymous

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.

    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.

    Until Microsoft fixes the problem I've renamed the file .old

    I can't see it doing anything.

    It's not infected which is a bogus answer.

    You can scan it till the cows come home and they will probably pour you a glass of milk.

    The file is bad and MS needs to produce a fix.  Scanning it for a virus has not produced results for anyone

    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.

    Hi,

    Thank you for posting your query on Microsoft Community Forums.

    From your issue description, I understand that the TiWorker is using 50 % of your Windows 8 computer.

    I suggest you to try the following trouble shooting steps and check if the issue persists.

    Method 1 : Run Online Scan (Microsoft Safety Scanner).

    A fast way to check for viruses is to use an online scanner, such as the Microsoft Safety Scanner. The scanner is a free online service that helps you identify and remove viruses, clean up your hard disk, and generally improve your computer's performance.

    To run the Microsoft Safety Scanner:

    a. Go to the Microsoft Safety Scanner webpage to download the scanner.

    http://www.microsoft.com/security/scanner/en-us/default.aspx

    b. Click Download Now, and then follow the instructions on the screen.

    Note: The Microsoft Safety Scanner expires 10 days after being downloaded. To rerun a scan with the latest anti-malware definitions, download and run the Microsoft Safety Scanner again.

    Note: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss

    You can also refer to the article mentioned below for more clarifications.
