Windows Modules Installer Worker causes memory hog

Hi,

Thank you for the reply.

Did you try to start the Windows Installer Module manually?

a. Press Win + R on the keyboard

b. Type Services.msc and hit OK

c. Right click on the service the options Stop and restart the service.

Hello,

The problem that we seem to be sharing appears to be with Windows Modules Installer Worker.

Using your Services.msc instructions allows me to access the Windows Modules Installer Worker properties but the options - Start, Stop, Pause, Resume, Restart - are all greyed out and none is selectable.  Incidentally, all of these options are greyed out in Windows Modules Installer, too. (I am running in Admin mode, in case that makes any difference.)

Using the Task Manager, I have been able to select the Windows Modules Installer Worker and then end the task.  The CPU usage drops right back down to single figures and the memory figure drops back down by about 50%; the Windows Modules Installer still seems to be working "normally".

Note: I just ran dism again. No corruption found. But the Windows Installer Module Worker is working away!

Thank you so much for replying. My laptop was finally usable after a horrible 8.1 update (which I had to reinstall everything from bare metal) and now it is unusable again after Update 1.

Step 1 - I ran the DISM tool three times. It found corruption, and then fixed it. I checked for updates again, there were several and I installed them. Reboot. Same problem. After about 7 minutes of 100% disk, I am back to the Windows Module Installer Worker using 50% or more of the CPU for several hours now.

I tried the built in troubleshooting. It found an error with the update and fixed it. Still have the same problem.

Step 2 - sfc refused to work. It says another servicing or repair operation is currently running...

Did you run the System file checker command on administrator command prompt?

Running the DISM tool and System File Checker tool help us to fix corrupted system files. Refer to these steps and check

Step 1: Refer to “Run the DISM tool” section. Please ignore the thread title.
