Fixing corrupted files in Windows 11 can be a straightforward task if you know the right steps. Essentially, you’ll use built-in tools like the System File Checker (SFC) and the Deployment Imaging Service and Management Tool (DISM) to identify and repair corrupted files. These tools can scan your system for errors and repair them automatically, bringing your files back to their original state. By following a structured approach, you can resolve file issues and restore your system’s integrity.
How to Fix Corrupted Files in Windows 11
Once you get the hang of it, fixing corrupted files in Windows 11 is simple. The following steps will guide you through using Windows tools to repair affected files and ensure your system runs smoothly.
Step 1: Open Command Prompt as Administrator
Press the Windows key, type “cmd,” and right-click on “Command Prompt.” Select “Run as administrator.”
Running the Command Prompt with administrator privileges is crucial for executing commands that require system-level access. This step ensures you have the necessary permissions to scan and fix corrupted files.
Step 2: Run System File Checker (SFC)
Type sfc /scannow in the Command Prompt and press Enter.
The SFC tool scans all protected system files and replaces corrupted ones with a cached copy located in a compressed folder at %WinDir%System32dllcache. This process can take some time, so be patient and let it complete without interruption.
Step 3: Use DISM Tool
If the SFC command doesn’t fix all issues, type DISM /Online /Cleanup-Image /RestoreHealth in the Command Prompt and hit Enter.
DISM uses Windows Update to provide the files required to fix corruption. It’s like a backup plan if SFC can’t replace corrupted files. It checks the Windows store for system errors and repairs them, ensuring your system’s health.
Step 4: Restart Your Computer
After the DISM process finishes, restart your computer.
Restarting your computer helps apply the changes made by SFC and DISM. It ensures that all repaired files are properly integrated and that your system is running smoothly with the updated, uncorrupted files.
Step 5: Verify File Integrity
After restarting, open the Command Prompt again and run sfc /scannow to ensure all files are fixed.
This final check confirms that no corrupted files remain on your system. It gives peace of mind that your system is back in good condition and ready for use.
After completing these steps, your Windows 11 system should be free of corrupted files. You’ll notice improved performance and fewer errors, as the integrity of your files is restored.
