Windows 10: 100% Disk Usage on Startup

Hello,

My problem is that Windows takes a very long time to startup despite it being on an SSD Rotating circles for a minute or so, and on further investigation it's because of the system disk having 100% disk usage which slows the entire computer down, and after using Windows Performance Analyzer, I saw that the "System" process is the biggest culprit, but it won't show specifics; also, opening any program immediately drives up disk usage to 100% and it only dies down after 5 minutes or so.

I've tried everything short of reinstalling Windows, and I'd prefer not to do that, so I'd appreciate all the help I can get. I can also send over the WPA file when needed. No updates are pending, but I've had many updates installed over time and they have not fixed this problem. This Windows installation is also just a few months old.

OS - Windows 10 Pro

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.

This article provides steps to disable prefecth and superfetch:

Windows 10 Disk usage 100% on startup

Hi,

I am facing an issue with Disk usage 100% on startup.

 

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.

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