After the latest Win 10 update, my disk usage started to hit 100% every time after booting the computer and it doesn't go down. I've tried to find a solution online, but nothing was helpful. In the end, I was pretty desperate, so I ended the process on Task Manager and it did went down to a normal percentage of 0-1%, but it always comes back when I boot my computer again. Also, virus and malware scan was clean. Is there any way to resolve this issue? Any help is greatly appreciated!

I have Lenovo G500, i3, 2,4GHz CPU and 4 GB RAM. It's year and a few months old.
