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

    AT LAST THIS DAMN REPLY FUNCTION WORKS INSTEAD OF SAYING OOPS THERE SEEMS TO BE A PROBLEM!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    Well after waiting half an hour this morning for my PC to finish the latest Windows update I have had enough.  That and the Windows Module Installer Worker slowing my PC to a crawl whenever it feels like it mean I am going over to manual updates.  I'm pretty sure I am never going to buy a Windows PC again too.

    That's not the solution for me. I've been having this problem since I installed Windows 8.1 last November on a brand new computer. I even formatted and re-installed Windows 8.1 a few days ago. I did all updates, including the optional ones. I have it set to check for updates but let me choose whether to download and install them (the option I always use) but it doesn't fix the problem. I've even tried killing the process but it just starts back up again. I have the process set as manual startup but that's clearly ignored. Why does it run for hours and hours and hours? I love having 30% of CPU hogged all the time. I don't know about other people, but I think I've reached the end of the rope with Windows -- too many years of too many annoyances.  I doubt Windows 10 will be any better. At least there's other options (OS/X and Linux -- which has its own problems).
