How To Quickly Fix 100 Percent Disk Usage On Windows 11

One easy way to identify the program or service that is consuming all of the disk space is to use Task Manager. You may select Task Manager by doing a right-click on the Start menu. Next, select the heading of the Disk column to see what’s consuming the most resources. From there, you’ll know just where to start. But the issue can be more significant than simply uninstalling an app or canceling a service. Therefore, please keep reading to learn about more likely sources of the issue and how to resolve them.

Disable Superfetch

The Superfetch feature, often referred to as SysMain in Windows 11, speeds up app loading and shortens boot times by reading a prefetch file. It is a helpful feature that speeds up performance, but it could also require a lot of disk space. Follow these procedures to deactivate Windows 11’s Superfetch (SysMain):

  1. Use the Windows key + R shortcut to open the Run dialogue.
  2. Type services.msc into the Run box & click OK.

In the Run box, type services.msc and press OK

  1. Double-click SysMain and select the Stop option after the Services panel opens.
  2. Next, choose Disabled from the choice next to the Startup type

Next, select Disabled from the selection menu next to the Startup type

  1. To close the Services console, click Apply and OK.

SysMain should have paused, and you should see a difference in Task Manager’s Disk Usage; but, to resolve the issue, you must restart your computer.

Rebuild Search Index

Search indexing is another common issue associated with Windows 11’s excessive disk use. Search indexing looks through files, emails, pictures, and other system files on your computer to deliver search results more quickly. Something going wrong could lead to an endless cycle of searches. But you could rebuild the database and fix it. Complete these procedures in order to rebuild the search index:

  1. Type “indexing options” into Start, press the Windows key, and choose the first result.
  2. Click the Advanced option when the Indexing Options window shows up.

When the Indexing Options box appears, click the Advanced option

  1. To ensure 100% disk usage, select the Rebuild option under the Troubleshooting section and press OK to validate.

In the Troubleshooting section, click the Rebuild option and then OK to confirm.

You should step away from your computer for a while as this process could take some time. Depending on the speed and data capacity of the drive—that is, SSD vs. HDD—the time needed may change.

Disable Search Indexing Completely

You can disable search indexing entirely if the rebuild functions properly but you find yourself needing to do it frequently. To turn off Windows Search, take these steps:

  1. Use the Windows key + R shortcut to open the Run dialogue.

2 – Type services.msc into the Run box & click OK.

  1. To access the Services console, double-click Windows Search.

Double-click on Windows Search when the Services console appears

  1. Choose Disabled as the Startup type when the Windows Search Properties window appears.
  2. Click Stop and then OK.

Select Stop

You can now disable search indexing and it won’t work if you restart your computer. Also check Ways To Fix The Most Common Netflix Issues

Disable DiagTrck Service

  2. From the menu, right-click DiagTrack and choose Stop.

Check Malware

Viruses and/or other malware should be checked for as well. This is very important. Windows Security, formerly known as Windows Defender, is an integrated program that scans your computer for malware on a regular basis. But it could only be able to record certain items. By doing the following actions, you can manually do a virus scan:

1 – Click Start, press the Windows key, type “windows security,” and select the first option that appears.

Press the Windows key or click Start, type windows security, and choose the top result

  1. Select “Virus & threat protection” from the menu on the left, then press the “Quick scan” option.

choose Virus & threat protection and click the Quick scan button

  1. Do a more thorough scan if nothing is discovered and your disk usage is still 100%. To accomplish this, click the Scan options link, then select Microsoft Defender Offline scan or Full scan.

 If nothing is found and you still have 100 percent disk usage

It takes longer to perform a more complete scan, but if your PC is infected with persistent malware, the wait will be worthwhile. Close any open files before starting an offline scan because it will restart. Getting a second opinion is also very important. Run a scan on any file you’re unsure about with a reliable, free security program like Avast or AVG AntiVirus. Also check How To Fix Instagram Links Not Working
