Windows 10: System itself causing 100% Disk Usage on PC after 20H2 and optional driver updates

Hello,

I am using Lenovo G-5080 with Windows 10 OS Build 19042.870. As the subject suggests disk usage is high at PC boot-up after the updates mentioned in the pic 1,2,3 from windows update are installed. By looking in the task manager, the System and Services host consumes the most of the disk space. The System Interrupts consumes 100% of the CPU after boot-up causing the slow down the PC. None of the application is opened during this process. All the Startup applications are disabled. The Laptop heats up during this.

Does anyone know solution for this? It would be a great help for me.

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Outdated AHCI driver will affect the system performance and result in 100% disk usage in Windows 10. Furthermore, outdated, missing or broken drivers can also cause other issues like Bluetooth not working, PC not waking up from sleep, etc.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

 

100% disk usage

The most common cause of 100% disk usage appears to be Superfetch and Prefetch, but there are also other causes. You can try disabling both these features and see if it helps.

How to Fix 100% Disk Usage Error in Windows 10

 

100% disk usage.

Summer has ended and my girlfriend booted her school laptop for the first time in months, only for it to be so unbearably slow that it took several minutes to log in. She handed it to me and said "fix it"... that was 3 days ago and now I am here to humbly
ask the community what is going on with this GD laptop.

It boots and task manager reports 100%CPU usage, it then lags for several seconds and displays 100%disk usage with CPU usage bouncing between 30-60%.

If you leave it alone with task manager running it will eventually quiet down to a reasonable 0-5% disk usage, but doing ANYTHING causes it to bounce right back to 100%.

I have tried EVERYTHING.

• disable superfetch.
• disable microsoft search.
• disable updates and suggestive tips.
• updated to the most current version of microsoft. (it hadn't been updated since 2018 when she bought it.)
• reconfigured AHCI PCIE.
• changed energy options.
• disabled indexing.
• reset the virtual memory.
• ran disk defragment and disabled all scheduling.
• updated all drivers.
• deleted google chrome.
• Disabled all services that weren't microsoft services and disabled all startup programs (clean boot).

Still no change in the disk usage.

Its an HP Laptop model 15-bw0xx with Windows 10 home edition version 10.0.18362

after messing with it this long im considering replacing the HDD with an SSD but I fear that it wont fix the issue.
