"...the solution is disable one or more programs/ services and see if the disk usage drops."
Also, the Google Chrome at the top helped me with the problem.
My problem of 100% Disk usage ALWAYS goes away in about 2 minutes. I had no idea a person with a SSD drive was having a problem with 100% Disk usage that never goes away. That is not the problem I am having.
Are these old laptops we are talking about that have new SSD drives installed? I did have to take Windows 10 64 bit off of my old AMD Duo Core X64 laptop for heating up.
Right now my HP Windows 10 64 bit AMD Quad Core A10 is reading 4% CPU, 26% Memory, 0% Disk, 0% Network in the Task Manager.
