Windows 10 100 % disk usage

Good Morning.... THANK YOU for your reply.   One step that I cannot seem to "find" is PROCESS DISK... 

 "then on top of same window page select 'Process disk' 'check' write, read, write bytes, read bytes"

I did finally find my culprit after trying all the 12 steps of (superfetch, defender off, 

resetting  

INTEL(R) ICH9M/M-E Family 4 prot SATA AHCI Controller - 2929 as follows: /EN_8086&DEV_2929&SUBSYS_FF1E1179&REV_03\3&3B1BFB68&0&FA       

That fixed it for 3 weeks 

Now April 29 2020: I downloaded a program -  Microsoft Windows "process explorer" downloads and select - unzip file and save to desktop. Open program and select 'view' and click on 'select columns' (bottom choice) -  I clicked top of window page 'Process I/O' and 'check' write bytes and read bytes - then on top of same window page select 'Process disk' 'check' write, read, write bytes, read bytes. click on graph I tightened the columns and looks for the program that gave me the most MB used in the left columns. I found a svchost.exe that was using 89MB and 34.7MB - under PID it was 2684 I suspended this line by right clicking on it and selecting suspend. When I right clicked on host process it says Xbox - I had taskmanager open at the same time so I coould see the usage dropped to 1-4% now - it's slow to open Chrome on CPU but works good after it's loaded. Hope this helps.

Just so you are totally aware of the environment, Win 10 is running on a virtual machine ( parallels v15 ) and I have ran disk utilities - Mac OS first aid no no errors . This is a 2019 iMac w/16gb ram

Standing by........................

To summarize: It may be a hard disk problem which I am trying to find using the steps I gave above.
