My Laptop always shows Disk as 100% in task manager and has become very slow because of that. What should be the solution to fix this issue

Disk Usage 100 % in Windows 10 degraded my system performance

Hi Zahid,

To help us identify the cause of the issue and then find the proper resolution for it, let us know if there were any changes made on the PC prior to the issue.

Since the steps you have taken didn't help, here are a few suggestions that you can try to resolve Windows 10 high disk usage issue:

Disable the Superfetch service.

This service is built to improve PC performance by speeding up the startup of programs and pre-loading the apps you often use into memory. If you don't do anything after powering on, it will still take up high percentage of the disk. To disable the Superfetch
service, follow these steps:

• 
  Press Windows key + X and select Computer Management.
  
• 
  Expand Services and Applications on the left column and click on
  Services.
  
• 
  Navigate to Superfetch and double-click on it, and then select
  Disable from the drop-down menu of Startup type.
  

Update the AHCI driver.

Outdated AHCI driver will affect the system performance and result in 100% disk usage in Windows 10. Furthermore, outdated, missing or broken drivers can also cause other issues like Bluetooth not working, PC not waking up from sleep, etc.

Let us know how it goes.

 

Clean install, disk usage at 100%

I've seen that article. and I am in fact not running that driver. I followed the steps and it does not appear in the list.

 

"System" Service Using 100% disk

Hi,

Thank you for writing to Microsoft Community Forums.

Did you notice any changes on the computer prior to this issue?

What is the make and model of the computer?

One of the possible reasons for this issue is Advanced Host Controller Interface PCI-Express (AHCI PCIe) running with AtorAHCI.sys driver. Please refer to the article:
Task Manager shows 100% disk utilization on Windows 10 devices

I also suggest to try the steps mentioned in the article: Improve system performance in
Windows 10 and let us know the status of the issue.

Hope it helps.
