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

    is true, the best way to fix this.

    windows automatic update never was trustable, is not trustable today and maybe never will be.

    don't believe in who says the opposite

    people must be slave of fear to think that update will really help us, i work with windows more than 15 years and updates brought me more problems than solution, the best to do is set as MANUAL or DISABLE it (taking updates only with setups) with that, you will take only what you need and know it is working. auto update is a timebomb, sometimes is comes with a killer update, is happened with windows 7 many times and happened with XP too, just wait for it again, is way better wait for what already was tested to use it, using auto update always was suicide!

    for everyone...

    not let it drain your PC, you have a lot of things better to do, and auto update will keep forcing your PC and suck your power for nothing, even when is already updated, why? well, i know but if i say, i will be banned...

    microsoft workers always will say "we not recomend to disable", because they are forced to say it, but major of those updates are useless, they NOT improveyour system security as microsoft say, only an antivirus not made by microsoft or a firewall will hold the line, everything that comes from microsoft is already dead when born, because almost all hackers or virus that is really dangerous, know how to break anything made by microsoft, and the main system defense never hold what we need to keep far, and use a browser like comodo dragon, firefox or sea monkey, all others lie about their defenses.

    the auto uptade not will help, he suck your CPU, not bring good updates all times, can bring an killer update, will install useless files, will drain your energy, will occupy your disc space,and not improve your security as we need.

    set as manual or disable. wait for what is good.
