Windows 10: 100% disk usage is always lagging my PC?

I have had Windows 11 installed on my Alienware PC with 2TB HDD and the 100% disk usage is causing my PC to slow down an awful lot meaning that downloading games from Steam and updating is causing an initial slowdown to my PC that I got in 2019 and it would go extremely slow when using it and the disk usage always reaches 100% it would cause the PC to slow down and what is the difference between HDD and SSD drive if the traditional HDD has slowed down my PC so often?

Disk Usage 100%

Hey

Thank you for the reply,but your suggestion proved no use to me still the disk usage remains 100 percent and my system lags in performance.

 

100% Disk Usage

So this thing started to happen me in May, but only 1 time.

In June, this happend few times, and my pc lagged.

Now I have 100% Disk Usage almost everytime, but, when it's not 100% disk usage, my PC still lagging.

I have a laptop Acer Aspire E5-575G-31LP with:

Intel Core i3-7100U 2.4 GHz, 3MB L3 Cache

NVIDIA GeForce 940MX 2GB Dedicated VRAM GDDR5

4GB DDR4 memory

1000GB HDD

Windows 10 Home OS

Why I have 100% disk usage?

Why laptop is lagging even if disk usage is not higher?

PS:I just reinstalled Windows and i have all drivers installed.

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.
