Windows 10 Persistent 100% Disk Usage Issue: Seeking Solutions After Exhaustive Troubleshooting

[laevatinx]

So, I had this pc for a while and just recently it's been running very slow. When I checked the task manager, I saw that my disk was constantly at 100%. For the past 3 days, I tried everything I could. From disabling windows search, disabling superfetch, running chkdsk a few times, fixing StorAHCI.sys, etc. Nothing has worked so far, and I'm starting to lose hope. Does anyone have a solution for this?

I would run procexp and identify which process is pegging the disk before we try to guess at the cause.
