How to Fix for 100% Disk Usage on Windows 10?

Fix for 100% Disk Usage on Windows 10:

If the Task Manager of Windows 10 is displaying 100% disk usage or there is something that is overloading your hard drive with work, then your system will become very slow and you will not be able to carry out any job using it. This issue can appear on its own. However, this issue can easily by resolved by following the simple solutions given below. 

Solution 1: Turn Off SuperFetch

SuperFetch will allow you to reduce boot time for the efficient loading of some programs. Enabled SuperFetch causes disk performance issues in Windows 8 and Windows 10. Worry not, as you can fix this problem by following the steps given below. 

Step 1: Press the Windows key on your laptop and then enter the "command prompt". After that, choose the option of Run as administrator. 

Step 2: Now, go to the prompt of the User Control Panel and select Yes. 

Step 3: After that, the command prompt will open up one more time. After that, you need to enter the command "net.exe stop SuperFetch" 

Step 4: Press Enter. 

Step 5: In case it shows that the command given above is invalid, then try the command "net.exe stop sysmain".

Step 6: Wait for a while and check if your computer is performing well or not. You can also check the disk usage on the Task Manager given in the Windows search bar. Now, go to the Processes tab and check the Disk column. If the disk usage is less than 100%, then that means the issue is resolved. 

Solution 2: Update Device Drivers

If the above solution doesn't fix your problem, then that may be happening because your device drivers are not updated. There are two ways of updating the device drivers. One is the manual update and the other is by using third-party software. If you don't have any technical knowledge, then you must update the drivers automatically. 

Solution 3: Do a Disk Check

Below are the simple steps that you need to follow for performing a disk check. 

Step 1: Press the Windows key and X key simultaneously on your keyboard and then select the option of command prompt. 

Step 2: Go to the User Account Control and select Yes. 

Step 3: The command prompt will open up one more time. Now, enter the command given below. Enter chkdsk.exe /f /r. 

Step 4: Press the Enter key on your keyboard and then select Y to confirm that you want to perform a disk check when you will reboot your computer the next time. Before you do so, you must make sure that all the applications are closed. 

Step 5: Once you are done performing a disk check, then you need to take a look at the disk of your computer one more time by going to the Task Manager. If you find that your disk column is not 100%, then that means the issue is resolved. 

Solution 4: Try Resetting Virtual Memory

Virtual memory is an extension given to the physical memory of your computer system. It is made by combining a part of your hard drive and RAM. When sufficient RAM isn't there to carry out the work, then files are stored in the virtual memory. When required, they are switched back to RAM. Below are the steps that you need to perform for resetting virtual memory. 

Step 1: Press the Windows key and Pause key simultaneously on your keyboard. After that, select Advanced System Settings given in the panel. 

Step 2: Navigate to the Advanced tab and then go to Settings. 

Step 3: After that, go to the Advanced tab one more time and select "Change" given under the Virtual Memory section. 

Step 4: Please make sure that the box "Automatically manage paging file size for all drivers" is not checked. 

Step 5: Now, choose your Windows drive and enter the maximum and initial size of your virtual memory. When you are done entering the values, select Set and then select Ok.

Step 6: Remove all the "Temp" files from your computer. Press the Windows key and R key at the same time. After that, type Temp in Run and then press Enter. This will launch the Temp folder of Windows Explorer. Moreover, it will display all the temp files on your system.

Step 7: Select all the files and remove them. 

Step 8: Now, check Disk usage. If it is not 100% anymore, then that means the issue is resolved.
