There are also different 100% high disk usage scenario:

There are added features like; Settings, Windows Store, GameMode, Apps, FastBoot (Disabling the F8 Option), Xbox App, Edge, TV's and Movie App, Groove Music, Windows Defender, Enhanced Security, Multi-Desktop Feature, Tablet Mode, Flight Mode, & more.

Different Scenario and Resolution

1. While browsing or using an application/s.

Two (2) major culprits are Google Chrome & Skype. Use this link: https://answers.microsoft.com/en-us/windows/forum/windows_10-hardware/how-to-fix-100-disk-usage-in-windows-10/7c5c979b-0ed0-4855-b9b8-05b9499533e2?auth=1

100% high disk usage can also come from Apps / Games (due to compatibility issue). Check on this link if your game is tested for Windows 10.

2. After PC Start-up but then go back to normal usage.

Check if you have any Start-up Task use auto run to do so: https://docs.microsoft.com/en-us/sysinternals/downloads/autoruns

If your operating system came pre-installed on your device consider System Reset: https://support.microsoft.com/en-us/help/12415/windows-10-recovery-options

But if your Operating System came from upgrade path consider going back to previous operating system. Let me give you a direct link for Windows 7 & 8.1. (Do not use Windows 8. It is not supported by Microsoft Answer Desk Anymore. So don't expect support for this operating system).

Make sure that you have a valid Windows 7 & 8.1 Retail Product key. If you don't have one, you can buy it from a third party store (Microsoft Store do not sell Windows 7 & 8.1 anymore)
