Ok, so, I formatted my pc a few days ago, and my disk usage was higher than before, before formatting the pc, Windows would always use 0% of my ssd, after formatting, windows started to use 1/2/3% of my ssd. I even bought a new ssd, and after installing Windows on the new ssd, the disk usage was still there.
So, i did a fresh install, but the problem was still there, i even formatted the ssd agai. Some things like svchost.exe services consume my disk, system, registry, and antimalware service executable consume my disk sometimes. It never went above 0%, that’s strange.
