How to Fix Windows 11 100 Percent High Disk Usage

Ideally, the disk usage in daily tasks is never more than 70% for an average user. If you run heavy applications or games or use multiple applications simultaneously, it can go up to 90%. Sometimes it is OK if the disk usage touches 100% when you are rendering heavy files or playing a game at high frame rates.

However, if your PC uses 100% disk on Windows 11, even while performing basic tasks like browsing the internet, opening files explorer, or running a video file, there’s something wrong. Multiple factors might be causing the issue.

Some of the factors that cause your PC to slow down and use 100% of your disk are –

  • Error in Pagefile.sys
  • Too many startup applications
  • A higher number of temporary files
  • Unoptimized PC
  • Malware Attack

The factors can be endless when it comes to justifying the lack of performance in a Windows PC. But the same has been the case for years now, and thanks to the vast community that Windows users have, we always have a solution to the issues that arise.

Check out how you can fix 100% disk usage of Windows 11 in the next section.

Best Ways to Fix Windows 11 High Disk Usage

1. Remove all the temporary files instantly

Temporary files are hidden user logs that are loaded on the disk. These are files that applications create on your system to store your user data for a particular session that you are using the app. Some applications are smart enough to collapse these files once shut; however, most Windows applications create and leave temporary files behind.

Removing these temporary files can reduce the load from your disk, freeing up the disk usage capacity instantly. You can remove temporary files from your PC by following the given instructions –

  • Press Windows + R to open the Run search box.
  • Type %temp% in the run and press enter

run command

  • It will take you to the folder that holds all the temporary files
  • Use Ctrl+A to select all the files and Shift + Delete to remove them.

Once you have removed the files, make sure you restart your PC. It is not necessary to restart the PC; however, it is always better to do it when you have made a substantial change. You may find lower disk usage after the PC reboots.

2. Shutdown SysMain Superfetch Service

SysMain service or superfetch is a service introduced by Windows to help you experience a faster operating system. It works is quite simple; it automatically pre-loads the applications into your PC memory to load them faster when you require them.

Ideally, it helps you load heavy applications faster; however, as a result of pre-loading, the applications that are not even being used start taking up your disk usage capacity. To resolve the issue, you can disable the SysMain service.

All you have to do is –

  • Press Windows + R to open the Run Box
  • Type services.msc and hit enter.
  • This will take you to the list of services available on your PC.

  • Find SysMain from the list and open its properties by double-clicking it.
  • In the properties window, disable the startup and use the stop button to stop the service immediately.

Once your PC has rebooted, open the task manager to check whether the disk usage has been reduced. You will see a difference of at least 10-15%.

Startup applications are those that start automatically when your PC turns on. These applications are designed to give you a flawless experience as you neither have to turn them On or OFF. However, these applications end up slowing your PC as the processes for these begin before the pc is entirely ready to handle.

Not to mention, these applications pre-occupy the disk usage capacity; hence, when you want to run applications, you find disk usage of 100 on Windows 11. The best way to handle this situation is by reducing the number of startup applications; here’s how you can do it –

  • Press Ctrl+Shift+Esc to Open Task Manager
  • Click on the Three-Lined Button on the Top Menu
  • Find Startup Applications in the Side Panel
