1. Check Your PC for Malware Infection

If your drive is constantly working at or near 100% for no apparent reason, this might mean your computer is malware-infected.The stakes are high – thus, scan your PC right away to find out if some malicious invaders are attacking your system.

Make use of:

Windows Defender

The Microsoft default security solution Windows Defender will scan your system for malware issues and do its best to make them cut and run:

Settings -> Update & Security -> Windows Defender -> Open Windows Defender -> Full

Your Main Antivirus

If you have a trustworthy antivirus program installed, let it do its job. Well, if not now, then when?

A Special Anti-Malware Tool

Your main antivirus is not omnipotent. You should back it up by any means whatsoever in order to protect your computer from irreversible damage. Consider using a special anti-malware tool to trace and remove the issues your main security solution may miss. For instance, Auslogics Anti-Malware is ready to help you.

2. Disable Your Main Antivirus Temporarily

Your main antivirus might be responsible for consuming 100% disk resources on your computer. Therefore, try disabling it temporarily to find out whether it is the one to blame for your drive going full capacity. You needn’t worry about your safety: Windows Defender can guard your system while your main antivirus is not at work.

If your computer’s disk usage returns to normal when your main security solution is off, you should contact your vendor and report this issue.

3. Turn Off Windows Defender

Windows Defender is your reliable ally against malware threats. It performs occasional scans even when your PC is protected by a third-party antivirus solution.

The problem is, Windows Defender might be on a collision course with your main antivirus. This can lead to excessive disk usage.

If you suspect such a conflict, try disabling Windows Defender:

  1. Start -> Settings, Update & Security
  2. Windows Defender -> Turn off Real-Time protection as well as Cloud-based Protection

4. Disable Windows Search

The frustrating 100% disk usage problem might be caused by Windows Search.

Although this feature helps you find your files quickly, try disabling it to fix the excessive disk usage issue:

  1. Windows Key + X -> Search box -> Type cmd -> Right-click Command Prompt -> Run as Administrator -> Yes
  2. Type net.exe stop “Windows search” -> Enter

Can you observe a reduction in the disk usage now?

If not, Windows Search cannot be blamed for the 100 % disk usage scenario.

In this case, feel free to enable Windows Search:

Go to Command Prompt again -> Type net.exe start “Windows search” -> Enter

However, if your disk is working properly after your turning off Windows Search, consider disabling this feature permanently:

  1. Windows key + R -> Type services.msc -> Double-click Windows Search
  2. Properties -> Startup type -> Disabled -> Apply -> OK

5. Turn Off SuperFetch

The SuperFetch feature is aimed at delivering fast OS boot. However, SuperFetch may lead to 100 % disk usage as well as sluggish performance.

Try disabling SuperFetch to sort out the Windows 10 disk usage problem:

  1. Windows Key + X -> Search box -> Type cmd -> Right-click Command Prompt -> Run as Administrator -> Yes
  2. Type net.exe stop superfetch -> Enter

Has your computer started to perform better?

If not, proceed to the following tip.

6. Disable Windows Tips, Tricks, and Suggestions

Some tips can actually slow down your PC instead of accelerating its performance. If you are sure you can do without Windows 10 tips and tricks, feel free to prevent your system from displaying them:

Settings -> System -> Notifications & Actions -> Turn off Get tips, tricks, and suggestions as you use Windows

7. Check Your Disk for Errors

Your disk itself might be the real culprit.

Check it for errors in order to resolve the annoying 100 percent disk usage issue:

  1. Windows Key + X -> Search box -> Type cmd -> Right-click Command Prompt -> Run as Administrator -> Yes -> Type chkdsk.exe /f /r -> Enter -> Type Y
  2. Close all your apps -> Restart your computer -> The disk check will be performed -> Keep in mind it might take some time to finish

8. Run System Files Checker

Missing or corrupted system files can cause your drive to work at or near 100 percent.

Try to spot and repair them using System Files Checker:

  1. Start -> Enter Command Prompt -> Right-click Command Prompt -> Select Run as administrator
  2. Enter DISM.exe /Online /Cleanup-image /Restorehealth -> Enter sfc /scannow
  3. Wait for the system scan to finish -> Reboot your Computer

9. Perform a Clean Boot

To find out what makes disk usage touch 100%, try performing a clean boot. It will load your Windows 10 with the fewest startup programs and drivers and help you find the culprit.

To perform a clean boot, follow these steps:

  1. Windows Key + X -> Search box -> Type msconfig
  2. System Configuration -> Services -> Hide all Microsoft services -> Disable all
  3. System Configuration -> Startup -> Open Task Manager
  4. Task Manager -> Startup -> Select the startup items -> Disable -> Close Task Manager
  5. System Configuration -> Startup -> OK
  6. Restart the computer

To identify the culprit after performing a clean boot, do the following:

Step 1. Log on to your computer as an admin
Step 2. Windows Key + X -> Search box -> Type msconfig
Step 3. System Configuration -> Services -> Hide all Microsoft services
Step 4. Select the upper half of the check boxes -> OK -> Restart

Does the 100 percent disk usage problem persist?

If it does:

Step 5.1. Repeat the steps 1, 2, 3 -> Select the lower half of the check boxes -> OK -> Restart

If it doesn’t:

Step 5.2. Repeat the steps 1, 2, 3 -> Select only the upper half of the remaining check boxes (the ones which are cleared in the list) -> Repeat these steps until you have checked all the boxes

Does the 100 % disk usage issue occur when there is only one service selected in the list? Then this service is the culprit.

Is there still no service to blame? Then keep going:

Step 6. Log on to your computer as an admin -> Windows Key + X -> Search box -> Type msconfig -> System Configuration -> Select the upper half of the check boxes -> OK -> Restart

Does the problem persist?

If it does:

Step 6.1. Log on to your computer as an admin -> Windows Key + X -> Search box -> Type msconfig -> System Configuration -> Select the lower half of the check boxes -> OK -> Restart

If it doesn’t:

Step 6.2. Log on to your computer as an admin -> Windows Key + X -> Search box -> Type msconfig -> System Configuration -> Select only the upper half of the remaining check boxes (the ones which are cleared in the list) -> Repeat these steps until you have checked all the boxes

Does the 100 % disk usage problem persist when there is only startup item selected? Then this startup item is the culprit.

All to no avail?

No worries, just keep working your way down.
