Windows Module installer worker is constantly running with very high CPU usage.

My PC has suddenly ground to a halt.

All the latest updates are installed as well.

I'm running Windows 8.1 Pro 64 + update.

Thanks.

In Windows 8 or 8.1 laptop, sometimes CPU fan run very fast and make noise because Windows Module Installer Worker occupies CPU more than 50%.

In this case, you can solve the problem by changing windows update into manual mode.

How to do it:

  1. Open services.msc (In Windows 8, WindowsKey+R and enter services.msc)
  2. Search "Windows module installer".
  3. Double click the "Windows module installer", and make it manual. It is usually set Automatic.
  4. Search "Windows update".
  5. Double click the "Windows update", and make it manual.
  6. Open Control panel(click the right button of your mouse at the lower left of you display monitor or LCD, e.g., at the Windows logo. and then you can see control panel menu)
  7. Click "Windows update"
  8. In left you can see "Change settings"
  9. Change the setting into "Check for updates but let me choose whether to download and install them". It is usually set automatic.
  10. Reboot

The Windows module installer workers cannot bother you anymore.

Important:

Because Windows update is set manual, you MUST check regularly (weekly or monthly) windows update by yourself.

Also, cleaning up your disk may help to reduce CPU usage by windows module installer worker

    Hi,

    I would request you to run chkdsk command to scan your hard disk if there is any corruption with disk or not. To check if your hard drive is causing the issue we can try running chkdsk command.

    Steps to run CHKDSK command.

    • Press Windows key + X.
    • Select Command prompt (Admin) from the list.
    • Press OK the UAC prompt if shown. That will open an elevated command prompt. (It will show Administrator in the caption.)
    • Then enter the chkdsk command

    chkdsk c: /f (or other drive letter if applicable).

    • Confirm to run on next startup and reboot.

    Computer can’t run a disk check while actively using Windows, but you can schedule it to start automatically the next time your computer is turned on.

    When the disk check is finished, your computer will automatically reboot. The disk check will fix any problems it encounters in your hard drive.

    Important: While performing chkdsk on the hard drive if any bad sectors are found on the hard drive when chkdsk tries to repair that sector if any data available on that might be lost

    Do keep us updated.

    Regards,

    Reply to self: Well, the reset took about two hours. On the screen was 'Configuring your Windows, do not turn off power'. After it *finally* came back, all was normal and CPU usage was just a few percent.

    I ran the Windows Update fixer-upper (KB971058), anyway and it found nothing to fix. Just as sfc and DISM also reported no errors.  So, Just Plain Weird. 

    Update history shows nothing was installed since 5 days ago. And the Store still has the same 4 apps to update so I have no idea what it was configuring. I resumed the Store updates and CPU usage initially spiked at 90+% and again when the install process started for each app, but it was 4% - 31% while downloading the apps (normal for an Athlon 64 3000+ CPU--hey, it works).
