High disk usage is a very common problem in many computers, which makes your computer slow down, freeze and makes it very difficult to work or use any application.

As we know, all the disks have a limited capacity of reading and writing, for the hard disks, this is from 100 Mbps to 150 Mbps on average; In the case of solid-state drives, the speed can increase to 500 Mbps or more, depending on the device model. Any process carried out in the operating system will make the disk read and/or write process to be utilized.

There are several reasons why a task manager can show that your disk usage is 100%, the most common are listed below:

• Lack of RAM

• Hard Drive wears

• Malware attack

There are some methods that can reduce 100 disk usage in Windows 10:

Method 1. Repair disk through CHKDSK

"CHKDSK" is a tool incorporated in Microsoft Windows operating systems that you can access through "Command Prompt". This tool is capable of checking the integrity of the file system of the disks and will carry out a repair and recovery process if it finds damaged sectors or corrupted information.

Step 1: Run Command Prompt as administrator

You can access this tool by typing "cmd" or "command prompt" in the Windows menu browser (don't forget to run in administrator mode)

Step 2: Run CHKDSK fix

Once you have opened "Command Prompt" in administrator mode, enter the following code "chkdsk c: / f"

Method 2. Run a virus scan with Windows Defender

As I mentioned before, Malware attack is one of the most common reasons for 100% Disk usage and the simplest way to fix this problem is by running a virus scan through Windows Defender. Below I'll show you how to do it.

Step 1: Open Windows Defender settings

Click on the Windows icon and type "Windows Defender" on the search box. Then click on "Windows Defender settings."

Step 2: Open Windows Defender Security Center

On the Windows Defender settings window, click on "Open Windows Defender Security Center."

Step 3: Open Virus & threat protection window

Now click on "Virus & threat protection."

Step 4: Start scanning

Click on "Scan now" and Windows Defender will automatically search for virus and malware.

Method 3. Update drivers

It is important to remember that Drivers are absolutely necessary for your computer hardware to function properly. When a driver is not updated, Windows will continue to try indefinitely to access a Driver that allows it to maintain control of the installed Hardware and this can generate high consumption in RAM and Disk usage. Fortunately, this problem is easy to solve. Below I'll show you how to do it.

Step 1: Open "Windows Settings"

There are several ways to access Windows settings but the easiest one is by clicking on the "gear" icon on the left side of the Windows menu.

Step 2: Go to "Update & Security"

Once you've access to the "Windows Settings" menu, click on "Update & Security"

Step 3: Click on Check for updates

Now all you have to do is click on the "Check for Updates" button and Windows will automatically search for and install any available updates.
