Windows Modules Installer Worker - high CPU usage

Anonymous

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:

Open services.msc (In Windows 8, WindowsKey+R and enter services.msc)
Search "Windows module installer".
Double click the "Windows module installer", and make it manual. It is usually set Automatic.
Search "Windows update".
Double click the "Windows update", and make it manual.
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)
Click "Windows update"
In left you can see "Change settings"
Change the setting into "Check for updates but let me choose whether to download and install them". It is usually set automatic.
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

I agree with Louise. It is impossible to get anything done with the automatic update enabled. I have used Windows products since they first came out and have never had the kind of trouble I'm having now. It is incredibly inconvenient to think I'm going to get some work done and have to wait at least an hour before I can use my laptop, because Windows is consuming all the resources every time I log on. I've had it gone over by a friend who works as a Microsoft troubleshooter at their data center in San Jose and am still having the same trouble. I don't usually use bad language, but that has changed when I have to fight with Microsoft ever time I want to use my own laptop.

Fine.

Unfortunately, we loose useful functionality in this way, as well.

Why is Windows Module Installer Worker so expensive?

I know it sounds a little bit "conspiracy theory-ish", but I too have wondered exactly the same thing as David Hervas did in his post above. I've added no new software recently (or for ages, in fact) to my Windows 8.1 machine, yet updates are becoming slower and slower (and heaven knows, Microsoft never figured out how to make them fast, or infrequently needed) in addition to which I end up with these accursed "installer worker" processes making my system fan sound like a C-47 on a takeoff run.

Windows Explorer is getting less and less stable; at one time I could rely on it to "just work", now I can rely on it to crash and restart and redraw my task bar if not constantly, certainly more regularly than I'd like.

Microsoft won't admit that Windows 10 WILL NOT run some of the software that we've shelled out money for (notably games that use DRM checks on CD-Roms) so what do they do? Sabotage that ability in Windows 7 and 8 as well so that they can say "Oh, but that software doesn't work on earlier versions either!" Given that kind of breach of faith I don't find it beyond the bounds of possibility that they could try to force us down the Windows X path by playing games like making the Installer Workers render a system borderline-unusable, and trying to frustrate us into getting rid of that irritating in-your-face-constantly pop-up in the hope that Windows 10 will be better.

I'll probably give in on Windows 8 when I'm at work (I'd rather use their bandwidth than mine for that bloatware) because I've never remotely liked the Win 8 family anyway. But the Win 7 Ultimate on my desktop? That old expression "pried from my cold, dead hands" comes to mind. (It seems less affected by the Installer Worker processes than my notebook is. Whether that's a hardware thing or an O/S thing I have no way of knowing.)
