All previous builds of Windows 10 have had the “100 % Disc Usage” problem when the drive installed was a mechanical hard drive. This was usually partially relieved by disabling notifications and windows search. It has also been more prevalent when running Google Chrome. This video looks at comparing a low specification OptiPlex 790 with a 2nd generation Intel Pentium Processor, 4 GB of RAM and a 3.5 ” Mechanical Hard Drive on Windows 10 Version 2004 with the Chromium Edge Preview and comparing it to Windows 10 Version 1909 with Google Chrome. In both cases a clean install has been performed and Windows 10 has been fully updated so there are no processes running in the background.
