100% Disk Usage In Windows 10

In this Windows 10 post, we will be showing you how you can hopefully fix the problem that is causing your PC or laptop to use 100% disk usage.

Usually, this is more of an issue when you first load into Windows 10 as it is trying to boot everything up and load any programs that you have in your startup list. However, if the disk usage is still not going down and remaining high at 100% then there could be something else that is causing the problem.

It could be as simple as a program is really hammering your disk usage, Windows 10 is updating, or worst-case scenario your hard drive is failing. But whatever the reason below we have listed a few things you can do to try and figure out what is causing the high disk usage on your computer.
