100% Disk Usage in Windows 11 Dell

Experiencing 100% disk usage on a Dell computer running Windows 11 can be frustrating, but there are several steps you can take to address this issue:

  1. Check Task Manager:
  • Press Ctrl + Shift + Esc or Ctrl + Alt + Delete and select Task Manager.
  • In Task Manager, click on the “Disk” column to sort processes by disk usage. Identify which process or application is causing the high disk usage.
  1. Update Drivers:
  • Outdated or incompatible drivers can lead to disk usage spikes. Visit Dell’s official website to download and install the latest drivers for your specific Dell model.
  1. Disable Superfetch:
  • Superfetch is a Windows service that can sometimes cause high disk usage. To disable it, press Win + X, select “Windows Terminal (Admin),” and type the following command:
    net.exe stop sysmain
  • Then, disable Superfetch permanently by running:
    sc.exe config sysmain start=disabled
  1. Check for Malware:
  • Malware can consume system resources. Run a full system scan using Windows Defender or a reputable antivirus program.
  1. Disable Windows Search Indexing:
  • Windows Search Indexing can contribute to high disk usage. To disable it, press Win + S, type “Indexing Options,” and select it.
  • Click “Modify” and uncheck all locations to prevent indexing.
  1. Check for Background Services:
  • Some background services can cause high disk usage. Review and disable unnecessary startup services. Press Win + R, type “msconfig,” go to the “Services” tab, and uncheck unwanted services.
