Very High Disk Usage Caused by Windows Event Log

Hi Erzawan,



Thank you for writing to Microsoft Community Forums.



I understand your query related to high disk usage on your PC. For further clarity on the issue, I would like to know the build version of Windows 10 that you are using.



Refer the article Which version of Windows operating system am I running?



Meanwhile, I would suggest you to try performing a Clean Boot on the PC to isolate the issue related to a background process causing Event Log to be triggered. Refer the article

How to perform a clean boot in Windows



Performing a clean boot will start the computer with minimal set of drivers and programs, to determine whether a background program is causing the issue. Some of the Startup programs will not load after performing a clean boot on the computer.
However, that functionality will return when you reset the computer to start normally after finishing the troubleshooting.



If the disk usage is normal after performing Clean Boot, then you can refer the section
How to determine what is causing the problem after you do a clean boot
from the Clean Boot article.



Note: Please refer the section
Reset the computer to start normally after clean boot troubleshooting to boot the computer in to normal mode after troubleshooting.



Let us know how it goes.

High Disk Usage


Hi all, I'm struggling with finding things to fix my high disk usage. I've spent many months searching the internet and doing all the listed suggestions like disabling SuperFetch, Windows Defender, Updating drivers, ect. and still I'm stuck with a high disk usage. Here's a screen shot I took immediately following a restart and opening up to a new Firefox window.





I have noticed Service Host: Local System takes up quite a bit of disk usage and that if I close it and let it open back up all by itself then it immediately makes my disk usage drop into a much more manageable 40-60% usage range. But eventually after a while it maxes out again and I have to close it out again. It's an annoying step just to be able to use my computer.

Also, I have noticed that after working with my mom's computer today, that her disk usage when no programs are running is only like 5%. Makes me wonder why my computer can have no programs running but my disk usage never drops below 30% and sits in the 40-60% range with spikes up over 75%.

I honestly don't know enough about computers to do much more than I already have without causing major issues. BTW, just a couple weeks ago I had to do a Windows reinstall, not a complete reinstall, just the basic reinstall they allow you to do on Windows 10 where you still keep all your personal files. Ever since that a lot of times when I try to open a process like Run or Task Manager I'll get an error message that it can't open and then I do it again and it will open the second time.

Here's a screenshot of my computer information so you can see what I'm working with here.
