Step #1 Disable Services
In Windows 10, there are quite a few services that affect disk usage and performance. Some of these, don’t even have anything useful to add. In this method, we are going to disable them.

The first service, that we want to change from automatic to disabled is Connected User Experiences and Telemetry. This service basically does nothing besides gather information for Microsoft.

Change the startup type to Disabled and click on the stop button.
The next service that we are going to disable is the SysMain service. SysMain analyses your usage habits and patterns. In return, it tries to optimize the launching of applications on your Windows 10 computer.

The last service that we want to disable is Windows Search. You generally don’t want to disable this but this service sometimes causes extensive disk usage. Hopefully, disabling these services has fixed the 100% disk usage problem.

Step #2 Fix Disk Usage with Windows Update

One of the things that has a surprisingly good chance to succeed is performing a Windows update. Click on the Windows search bar and type in Windows Update Settings.

This should open the Windows update menu. It’s possible that you already have an update available. Click on download and install to continue.
When this is done, reboot your PC. After that, you can check if the 100% disk usage issue is resolved.

Step #3 High Performance Settings

In the next method, we are going to change the power settings to a high-performance plan. To do this, click on the Windows search bar and type in power & sleep settings.

Scroll down and select Additional power settings. Once you open it, you should see your current power plan. We want to change this to a high-performance power plan.

The newly created plan is going to be set automatically. The high performance plan, in general speeds up your computer by a bit. It prefers performance over energy conservation.

Step #4 Disk Defragmentation – 100% Disk Usage

In the next method, we are going to take a closer look at the Windows disk defragmenter. What this does, is rearrange fragmented data so that your disks and drives work as efficiently as possible. It happens that this process gets corrupted by malware for instance and that it pushes the disk usage to 100%.

Search for Task Scheduler in the Windows search bar.
Navigate to the following location: Microsoft – Windows – Defrag. You can consider disabling the ScheduledDefrag if your disk usage issue was solved after ending this task.

Step #5 Fix a 100% Disk Usage – Virtual Memory

Next, we can try changing the Virtual Memory settings of the PC. Virtual memory is basically a swapping technique that allows your PC to use Disk as if it uses RAM.

First, you want to uncheck the box next to Automatically manage paging file size for all drivers. Then you can choose to set a custom size which is a viable option but for this tutorial, we want to select no paging file. Click on Set follow by clicking on Yes.

Hopefully, changing the virtual memory has fixed the 100% disk usage problem in Windows 10.

Step #6 Short Mentions

-Sometimes, malware can be the cause for spikes in disk usage. What you can do is have your antivirus software do a full scan of your PC. If you don’t have antivirus software, you can install one and then do a full scan.

-You can try to temporarily disable your antivirus software. This is of course only if you have antivirus software. It happens that virus scanners are responsible for disk or other performance-related issues.

-Temporarily uninstall Google Chrome. Chrome is known to have settings that can affect disk usage. You can test if this is the case for you by uninstalling Google Chrome and trying a different browser for a short bit.

-If nothing else works, you could perform a system reset. With a system reset you can reinstall Windows and keep your files if you want to or you can delete everything and reinstall Windows.

This concludes our how to fix a 100% disk usage in Windows 10 tutorial.
