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

    No offense meant toward you, but Microsoft shouldn't make us HAVE to do this. We should get a notice asking for permission to do it. Not an all or none approach. If I'm busy, I want to wait. If I'm only doodling around, then fine. Ask me, do not tell me or stomp away when I don't want to. 

    What I'd like to see Microsoft do is actually NOTIFY people what's happening in the background AS IT'S HAPPENING!

    Oh but no, they want to be so secretive on what they're doing it's pissing people off. Their machine starts HAMMERING the hard drive and CPU, sometimes for an hour. Meanwhile their computer is almost unresponsive prompting them to take it into a computer shop to find out why it's so slow.

    If they would just leave a notice on the screen on what they're doing I believe that would dismiss a lot of anger people have towards the computer (a.k.a Microsoft).

    I don't know how I could agree more! :-/

    I agree with Louise. My little notebook spends more time updating than it does actually being usable. Turning off automatic updates is the way to go.    

    I have a new little Acer Aspire V5 and it can't not be used with Windows.

    It Always updates, for nothing. Same problems every day.

    1. Hostproces voor Windows-services.
    2. Sevicehost lokal system.
    3. Service lokal service.
    4. Servicehost DCOM service process laucher.
    5. Service Host network.

    6. Windows Module installer.

    1. Windows start menu8
    2. Runtime proces cliënt service.
    3. System.
    4. Antimalware service excuteble
    5. ETC

    All this 80% of my Cpu!!

    Wen i open windows expore it gets laggy and verry slow.

    The store where i bought my Acer couldn't help me.

    He recomendet to install a outher OS Because windows have many problems

    and many customers are not satisfied with windows on little laptops.

    Any advice????

    It's like trowing 400€ in the trash!!

    Next laptop will be with an other OS

    Thanks
