Some other ways to try to fix your Windows 10 system’s storage space use. Due to the stress and additional use that your disk drive is already experiencing, one might take longer than usual. Some authentic and tested ways to fix 100% disk usage are listed below:

  • Switch from balanced to high-performance energy options.
  • Immediately stop the superfetch service.
  • Run Check Disk in Windows 10 to Reset Virtual Memory
Turn OFF Windows Search

Restart Your System

You’re fully aware that restarting your computer often can address a range of problems. Your 100 percent additional disk issue in Windows 10 is no exception. While this methodology may not help you learn the cause of the problem, if it fades away, it could be enough for you.

You should use the “restart” option to start your system from scratch, rather than the “shut down” button, which retains your state of the system but may not address your storage problems.

Restart Your System

Update Windows

Updating the updates on your Windows 10 PC can often resolve unexplained problems. Go to the “Update and security” area of the Windows Settings application to see if you’re up to date. You can check for new versions and, if any are available, install them. 

Settings > Update & Security Settings > Windows Update

This could increase the overall efficiency of the system, such as the performance of your hard drive.

Disable Windows Search

A known problem in Windows 10 might result in a search loop, which can lead to excessive storage use. To temporarily deactivate Windows Find and see if it helps with your storage problem, open an administrator prompt and type net.exe to disable “Windows search.” 


This one will disable Windows search until the operating system is rebooted.

If it turns out that Windows Search is to blame for your Windows 10 storage usage approaching 100%, you can permanently disable it by following these steps:

  • Enter services. msc by pressing the Windows key + R and pressing Enter.
  • The window for services will appear. To update the properties of the Windows Search item, double-click it.
  • Save the settings, select Disabled under Startup Type, and then OK.

Check For Malware

Your computer might be infected with malware, leading to increased storage use. Antivirus software should have detected the problem if it was running in the background. But since nothing is flawless, make sure your antivirus software scans your disk drive for any possible infections.

Check For Malware

Since your drive is already overloaded, this could be a time-consuming procedure, but it may be important to find and eliminate unnecessary software.

By default, Windows’ built-in antivirus will execute in the meantime and attempt to block any harmful files that try to enter your system. You may automatically perform a scan if you want to do occasional random inspections.

To do so, go to “Windows Security” > “Virus & threat protection,” then select “Quick scan.” 

If you want a more complete scan, which will take longer but will check all of your files and running programs, select “Full scan” from the “Scan options” menu.

If Windows finds malware during the scan, click the “Start actions” button to start uninstalling the virus from your system.

Stop The Superfetch Service

The Windows Superfetch service is yet another Windows 10 feature that can prove problematic. With the command net.exe pause superfetch, you can try resetting this service, similar to how Windows search works.

Use the same technique as for deactivating Windows search to completely deactivate the program.

Change Energy Options from Balanced to High Performance

For a handful of users who have encountered 100% storage utilization on Windows 10, this tweak in energy settings appears to have worked.

  • Select Power Options from the drop-down menu. 
  • Change the plan’s parameters > Advanced power parameters can be changed.
Change Energy Options from Balanced to High Performance

Select High-performance from the drop-down box, and make sure that all plan settings are left alone.

Whether you’re having problems with audio crackles, dropouts, or even other low-performance issues and your power plan is set to “balanced” or “power saver,” we recommend changing to the “high performance” power plan. It uses more power, but it should enhance people’s lives.

Temporarily Turn Off Your Antivirus Software

Turning off your antivirus software temporarily is another step to take while analyzing the cause of your Windows 10 100% storage utilization problem. Check to see whether

Temporarily Turn Off Your Antivirus Software

this reduces your disc consumption. If this is the case, you might consider switching to antivirus software. Even Windows Defender can cause issues by raising I/O and network traffic, potentially leading to significant CPU utilization.

Reset Virtual Memory in Windows 10

When virtual memory runs out of genuine RAM, it considers your storage as if it were RAM and uses it to swap out temp folders. Defects in the pagefile.sys file can lead your Windows 10 PC to exhaust all of its hard drive space. Resetting your memory space settings will solve the problem.

  • Click on “Advanced system options” in your computer’s “System Settings.”
  • Inside the Performance section, select “Settings.”
  • Select the “Change” button on the “Advanced” tab.
  • Make sure the “Automatically manage paging file size” box is selected.
  • You can alternatively select “No paging file,” click OK and reboot. This will stop memory space from being used and may improve your system’s disc performance.

Run Check Disk

A test drive can show if your hard drive has had any physical issues. Storage space consumption usually indicates an application or conceptual problem, but it’s worth your effort to verify any physical damage. Check the drive and take note of the results.

Run Check Disk

Change settings in Google Chrome and Skype

Making these modifications to your Google Chrome and Skype settings have been found to decrease the storage used by some users.

  • Enable the preferences menu in Settings.
  • Disable the “Use a prediction service to load webpages more quickly” option in the Security section.
  • Disabling Flash on Google Chrome is also a smart option.
