Fixing corrupted files in Windows 11 can feel like walking through a maze, but it’s simpler than you think!

We’ll show you how to use built-in tools like the SFC (System File Checker) and DISM (Deployment Imaging Service and Management) to fix the problem.

How to Fix Corrupted Files in Windows 11

The following steps will guide you through the process of diagnosing and fixing corrupted system files on your Windows 11 machine. These methods are safe and effective, ensuring that your system gets back to its optimal performance.

Step 1: Open Command Prompt as Administrator

Start by opening Command Prompt with administrative privileges.

To do this, press the Windows key, type "cmd," right-click on Command Prompt, and select "Run as administrator." You’ll need administrative rights to execute the commands required for fixing system files.

Step 2: Run the System File Checker (SFC) Scan

Run the SFC scan to check and repair corrupted files.

In the Command Prompt window, type sfc /scannow and press Enter. The SFC tool will scan your system files and replace corrupted ones with cached copies.

Step 3: Wait for the SFC Scan to Complete

Wait for the scan to finish.

This process might take some time, so be patient. The tool will notify you whether it found and repaired any corrupted files.

Step 4: Run the DISM Tool if SFC Fails

If SFC doesn’t fix the problem, use the DISM tool.

Enter the command DISM /Online /Cleanup-Image /RestoreHealth into the Command Prompt and hit Enter. DISM will attempt to fix system image issues that SFC couldn’t handle.

Step 5: Restart Your Computer

Reboot your system to apply the changes.

Restarting your computer ensures that any repairs made by SFC or DISM take effect. Always save any open work before restarting.

After you complete these steps, your corrupted files should be repaired, and your system should run more smoothly. If the issue persists, you might need to look into more advanced troubleshooting methods or seek professional help.
