Windows 10: HDD is running at 100%

This has been a problem going on for more than about 2 years. I've never been really able to find a solution as I've scoured through the internet looking for tutorials.I've triedisk checkingDefragmentationDisabling SysMain Disk clean upI eventually stopped looking for a solution since i genuinely couldn't find a fix and it wasn't much of a hassle when I'm playing something. But recently after a windows update it got much slower compared to before.

HDD drive constatly running at 100%

I have tried various suggestions when trying to stop the HDD from running at 100% and slowing the machine down. What I try works for a while, but soon afterwards starts again. Has Microsoft come up with a reason for this yet and found a cure?

100% Usage on Secondary HDD

I'm sure that isn't a problem with my HDD. I've just bought this brand new WD 4TB HDD. And on the top of this inquiry, I mentioned that something wired is that the 100% usage jumps between HDDs. It's disk E,F,G this time and it would be disk C,D or H,L next
time after I restart.(I have 3 Secondary Hdds).

The 100% occurs only when some applications are making use of the disk, such as file copying.
