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

    My usual morning routine is to wake up early, 0615 or thereabouts and switch on my PC. I often receive an email referring me to the latest input regarding Windows Module Installer Worker (WMIW) and today was no exception. I didn't pay too much attention, but just prior to hibernating the thing so I could have breakfast I noticed quite a lot of disk activity, Task Manager revealed WMIW was taking up 35% CPU at 0735 I decided to 'restart' rather than hibernate.

    The usual message came up, 'Getting Ready-Don't turn off'. The restart completed at 0833. I was able to see that many updates were installed yesterday, Dec 14th, none have been installed today.

    This topic has been going on now since May 2014 when it was happening with Windows 8.1.

    I would like to ask a few questions, perhaps some have been answered on the 17 pages on this topic but I haven't the time to look at all.

    1. Does anyone working for Microsoft ever look at this website?
    2. If 'Yes' does anyone working for Microsoft actually care about this long standing problem?
    3. It is unlikely that Q2 will be answered with a 'Yes' but just in case it is it would be interesting to know why some people are suffering from the problem much more than others, also is there ever likely to be 'fix' or is it something we have to live with until Windows 11?

    Good post.

    You are echoing exactly what thousands of other people are saying.

    Bought a brand new HP from Office Depot for a friend six months ago,

    and already had to work on it because of MS crap 10.

    I have several Win10 machines that I take care of, and there isn't one

    that has not had problems.

    A different story with Win7, they just keep on going without a hitch.

    This is ridiculous already.

    We need a fix.
