Windows 10: Need help narrowing down cause of 100% disk use

Hi there!

I've been having problems with 100% disk use on my HP Pavilion Laptop for a long time (a year?), generally without seeing what I would imagine are high read/write rates. It's gradually gotten to the point where the machine is super slow from 100% disk use about half of the time, which as I'm sure you can imagine is very aggravating. It's an HDD, and the current OS version is Windows 10 Home Version 1909. I have only 8GB of RAM, but this happens even when I'm using only 60% of it or less.

I've read some of the other threads on this forum about similar issues, but I'm only moderately techy and a little bit confused about where to start. I'm too busy to just try every single random online "fix" for this symptom, and it seems like maybe people here could help me more efficiently get the bottom of it.

I'm attaching some screenshots from Resource Monitor to get started. Happy to provide other information as needed.









Any and all help very much appreciated!

Disk is always at 100%

Hi Richard,

Some bugs or disk drive errors may cause high disk utilization. If your task manager shows 100% disk utilization, you may need to optimize Windows by following these troubleshooting methods:

Disable Windows Search

Some bug in Windows 8, 8.1 and 10 causes some "search loop" that causes maximum utilization of your disk. To disable
Windows Search, kindly follow these steps:

• Press Windows + R to open Run.
• Type services.msc and press Enter.
• Scroll down to find Windows Search, right-click it, and select
  Properties.
• Change the Startup type to Disabled and save the changes.

Disable Superfetch Service

Superfetch service has been identified as a possible cause of 100% disk utilization on Windows 10. To disable Superfetch service, kindly follow these steps:

• Press Windows + X and select Command Prompt (Admin).
• Type net.exe stop superfetch and press Enter.
• Wait for a minute for the changes to apply and close the Command Prompt.

Let us know how things goes.

Regards.
