Windows 10: Disk at 100% task manager

My old PC is very slow and say the disk is at 100%, I understand that it is old hardware, I would like to know some recommendations on what I should replace in the computer and if there would be any configuration needed if I replace the hardware Thanks in advance

Task manager showing disk usage 100%

100% disk usage can have many causes.

What are the top 5 processes listed in the task manager using the disk?

 

Task Manager has Disk at 100% when only 0 - 3 mg are shown as used

I have:

1) Formatted my disk and partitioned it as needed for Windows 10

1) Installed Windows 10 Home Edition 64 bit

2) Disabled Superfetch

3) Disabled Windows Search

4) Disabled BITS

5) Uninstalled Skype and SkypeHost.exe

6) Set MSISupported to "0" in registry

After each step I would reboot my computer and get the same problem 100% Disk in Task Manager

2) Installed Norton Antivirus and disabled Windows Defender and rebooted.

1) The system booted and hit 100% in Task Manager for about 5 minutes.

2) Attempted to open Windows Notepad and the Task Manager went back to 100% Disk.

In all instances the Task Manager Disk Listing would show between 0.3 and 2.5 total usage and still show the Disk at 100% on the top freezing the computer.

 

Clean install, disk usage at 100%

I've seen that article. and I am in fact not running that driver. I followed the steps and it does not appear in the list.
