How to Use DISM to Repair Windows 11: A Step-by-Step Guide

If you’re encountering issues with your Windows 11 system, using the Deployment Imaging Service and Management Tool (DISM) can help repair any corrupted system files. This tool scans and fixes your Windows image, ensuring your system runs smoothly again. Here’s a step-by-step guide to using DISM to repair Windows 11.

How to Use DISM to Repair Windows 11

Before diving into the steps, it’s important to understand that using DISM will help fix any corrupted files in your Windows 11 image. This process involves scanning your system for issues and restoring any damaged files from online sources or a local recovery image. Let’s get started!

Step 1: Open Command Prompt as an Administrator

First, open Command Prompt with administrative privileges.

To do this, type "cmd" in the Start menu search bar, right-click on "Command Prompt," and select "Run as administrator." This ensures you have the necessary permissions to use DISM.

Step 2: Scan the Health of Your System with DISM

Run the command: DISM /Online /Cleanup-Image /CheckHealth.

This command checks if your Windows image has any corruption. It only takes a few moments and won’t make any changes yet. It helps determine if a more thorough scan is needed.

Step 3: Scan for Corruption and Restore Health

Run the command: DISM /Online /Cleanup-Image /ScanHealth.

This will perform a more detailed scan and will take a bit longer. It checks for corruption and logs any issues found. This step prepares your system for the repair process.

Step 4: Repair Your Windows Image Using DISM

Run the command: DISM /Online /Cleanup-Image /RestoreHealth.

This command will repair any detected corruption using Windows Update. It might take some time, so be patient. It’s important not to interrupt this process to avoid further issues.

Step 5: Restart Your Computer

Once the repair is complete, restart your computer.

Rebooting ensures that all changes take effect and any repaired files are properly loaded into the system.

After completing these steps, your Windows 11 should be running smoother, with any corrupted files repaired. If issues persist, further action may be needed, but DISM often resolves many common problems.

Tips for Using DISM to Repair Windows 11

  • Always run Command Prompt as an Administrator to avoid permission issues.
  • Ensure your internet connection is stable, as DISM may download files from Windows Update.
  • Be patient; some of the scans can take a significant amount of time.
  • Consider running the System File Checker (SFC) tool after DISM for additional repairs.
  • Keep your Windows 11 system updated to prevent future issues.
