Hi,

Does the issue persist if you boot your computer in Clean Boot? If so, I suggest you run SFC/scannow command to check system file integrity first, then check whether your system need to update.

This servicing stack update did not do anything to fix the problem when the Windows Module Installer Worker was just  beating on my new hard drives.  As I was downloading this update, a task began looking for updates and then ended with a message that this update was not correct for my computer.  Eventually I shut the computer off and when I got up the next morning the Installer Worker began hammering away again.  I opened up the Task Manager and ended the Worker task but it restarted and this update began reinstalling and ended with "This update is already installed" and the Worker then stopped.  It took a moment until I decided to retry the Windows update KB278119 that fails with error 80070003.  After the update failed, the Worker started and began the heavy disk access.  I ran the reinstall on this update and the Worker stopped again.  So every time I do updates and one fails I guess I'll reinstall this update.  

Something is wrong with the Windows Module Installer Worker, when an update fails, it just keeps running with heavy access on the hard drives.

I found a solution tot his problem and is quite simple!

This is what i did..

Open Task Manager and End the task

Then if everything closes on your desktop no worries

CTRL+ALT+DEL and Click Task Manager

When it opens up go up on the left top corner and click on File

Select '' Run New Task ''

In the box that pops up type in   explorer.exe

Hit enter or okay and thats it :)

It won't come up till the next time you start the computer but im sure there is a fix to disable it from starting up all the time in the Schedule Task menu just don't know where bouts to find it but this is the best i could come up with for now and it works :)

If you go to the windows update settings and set it to "Never check for updates" it'll stop slamming your CPU. Worked on mine. 

Didn't work on mine, WMI Worker comes on idle, at least 5 minutes when keyboard+mouse+touchpad didn't touch and dissappear it self only if i touch one of it. Weird, WMIWorker behave just like a malware or something like that.

ps. even all the windows have been updated, it is still happening

I built a Windows 8 VM to beat on it and here's something that I discovered. I deliberately entered into one of those endless survey loops and they proceeded to load up the system with their malware, spyware, junkware. The system was bogged to a crawl.

I proceeded to uninstall each offending software through the control panel and slowly it started coming back to life. Once all the junkware was removed I noticed the Windows Module Installer was pegging the CPU. Reboot ... same thing. But after a little bit it calmed down and the system is normal.

I guess I'm thinking a good scan of the system to maybe pull out some leftover crap might be in order. I was thinking the malware uninstallers were still running in the background somewhere and the service was picking it up.

Just an observation.
