A problem affecting many computers running Windows 10 is overuse of the disk. The 100% disk usage in Windows 10 in fact, causes significant slowdowns when using the PC, and prevents us from doing our work in peace. To check if your pc is also subject to this problem, just go to the Activity Manager and check the percentage of disk usage.

100% Disk Usage in Windows? Here’s How to Fix It!

1. CHECK THE HARD DISK

To make sure that our hard disk is in excellent condition, we must proceed with a test. We can use specific programs, such as HDD Regenerator or simply use what Windows offers us (as in this case).

  • Right click on Start and select the item Windows PowerShell (administrator);
  • Type the command chkdsk / r and press Enter. Confirm by typing the S. At this point you can proceed with Windows restart. During the boot phase, the chkdsk utility will analyze the status of the disk and correct any errors.
2. DISABLE STARTUP PROGRAMS IN WINDOWS

If we keep too many programs running automatically, our PC will be slowed down both at power up and during use. In fact, we not only have to wait for the loading of all the software present, but these software remain running in the background, committing important resources.

3. DISABLE ANTIVIRUS OR INSTALL ANOTHER ANTIVIRUS

Antiviruses are heavily involved in our PC, especially when antivirus and anti-malware scans are in progress. To understand if the antivirus is the problem, we can temporarily disable it and check the status of the disk. It is always advisable to choose antivirus not too heavy especially if we own a pc with not very good hardware.

4. DISABLE WINDOWS UPDATE

Another great way to prevent our pc from slowing down terribly because of the “too many requests” it is running is to disable automatic system updates. In fact, even if these updates are made in a completely “non-invasive” way, during the download our computer could slow down especially if we are already exploiting a lot of resources. A good way to do this is to manually manage the updates, activating and deactivating them according to our needs. Here is the list of methods available for disable Windows Update.

5. CHANGE SETTINGS IN GOOGLE CHROME (PREFETCH)

Some Google Chrome settings may use hard disk resources. Here’s how to fix those settings:

  • In Google Chrome, go to Settings;
  • Scroll down to the bottom of the page and click Advanced;
  • In the Privacy and Security category, make sure the “Use a prediction service to load pages more quickly” is turned off.

6. DISABLE WINDOWS SEARCH

Another service that can cause the 100% disk usage in Windows 10 is Windows Search. Windows constantly scans the files on our computer to index them and make them available (as quickly as possible) during a search. If you can do without this service, we can disable it. Here’s how:

We press the WIN + R buttons, type services.msc and click on Enter. We are looking for the Windows Search service and select it with the right mouse button. Click on Properties. From the drop-down menu related to the Startup type entry, we set Disabled.

7. DISABLE SUPERFETCH

The Windows SuperFetch service monitors the user’s behavior, and stores which files and applications we use more frequently to allow faster start-up when required. Turning it off is very simple. In fact, just open the Command Prompt as an administrator (Windows PowerShell – administrator) and type the command: net.exe stop superfetch.

8. DISABLE INTEGRATED NOTIFICATIONS ON WINDOWS 10

If you do not use the integrated notifications on Windows 10, we can also disable them so as to lighten even more the workload of our PC.

Let’s get back to Start – Settings – System – Notifications and Actions;
Disable the item Get suggestions when using Windows and any other items that we do not deem necessary.

9. REPLACE THE HARD DISK WITH A SSD

This ninth point is what we wanted to put first. Or replace the hard disk with an SSD. Solid state drives are more suitable for operating systems such as Windows 10. The difference in performance is a lot.

As we have seen there are several factors that can cause the problem of 100% disk usage in Windows 10, we tried to incorporate them in this guide so you can test the various steps and identify the cause.
