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 guys, thanx so much for this post, over 2600 people have this problem, how many 100,000's more dont realise the issue and how their machines are routinely hammered

    On  a modest laptop <$500 what a joke W10 is.  These big store should be removing them off their shelves as they are totally unsuitable for even simple browsing (like haing a little 1000cc engine put inside a 10 ton truck) as I have discovered on my new Lenovo yoga. The CPU mostly hits 100% and the cursor becomes jerky and unusable

    That said one poster advised turning off the auto indexing of files.  For me that made a significant improvement - so far

    But what is truly scary is that M$ has taken control of my machine and will do whatever it wants and I cant realistically stop this nor all the data its collecting on my habits etc

    I have got to the extent of removing all personal data from the machine (keep it on a thumb drive) and run offline if needing to do something personal

    But its not a real fix, cos the minute I reconnect, then M$ poounds my machine with its monstrous downloads and I can only delay installation as it inevitably throws it into my machine in the early hours (and this can take an hour of two - what the hell is going on????????

    Worse still was the appalling arrogance of using my machine as a local hub to redistribute M$ mantra without my knowledge or permission (till I came here)

    I am doing my on line stuff on my old faithfull XP machine where I AM IN CONTROL

    I am seriously thinking of getting a 2nd hand W7 machine to mirror my XP m/c

    Does anyone feel as I do that this whole virus scare is way out of reality for the small time home user (naturally using zonealarm firewall and aviva .  Ive never had so much as a sniff (few false alarms), but I never go near dodgy websites or open files stupidly

    Cheers and thanx

    Fortunately I'm not bothered so much as I was with the Modules Installer Worker but now I often find my CPU is working at 35% or more. Task Manager reveals that the guilty process is 'System' so of course I haven't the faintest idea what's going on. Even if I try to hibernate or shut down the thing refuses to do so, the disk activity light continues to flicker, monitor has gone off so I go off to return eventually to find the monitor displaying the 'welcome' screen. I suppose I should raise another thread, post or whatever to report 'Excessive CPU usage due to 'System'' but seeing how well Microsoft are dealing with the modules installer worker problem I guess it would be a wasted effort.

    Hopefully by posting this I am not inviting Microsoft to inflict me with the 'Windows Modules Installer Worker' problem again.
