Fixing corrupted files in Windows 11 can be done with built-in tools like the System File Checker (SFC) and Deployment Imaging Service and Management Tool (DISM). These tools can scan your system for corrupt files and restore them. Here’s how you can do it, step by step.
How to Fix Corrupted Files in Windows 11
Using these steps, you’ll be able to identify and repair corrupted files on your Windows 11 system, ensuring it runs smoothly and efficiently.
Step 1: Open Command Prompt as an Administrator
Open the Command Prompt with administrative privileges.
To do this, click on the Start menu, type “cmd” in the search bar, right-click on “Command Prompt,” and select “Run as administrator.”
Step 2: Run the System File Checker (SFC) scan
Type sfc /scannow and press Enter.
This command will start the System File Checker, which will scan all protected system files and replace corrupted ones with a cached copy located in a compressed folder at %WinDir%System32dllcache.
Step 3: Wait for the SFC scan to complete
Allow the scan to run until it finishes.
This process might take some time, depending on your system’s speed and the number of files needing repair. Make sure not to interrupt the scan.
Step 4: Check the scan results
Review the results once the scan is complete.
The results will tell you if any corrupted files were found and whether they were successfully repaired. If some files couldn’t be fixed, you’ll need to use the DISM tool.
Step 5: Run the DISM tool
Type DISM /Online /Cleanup-Image /RestoreHealth into Command Prompt and press Enter.
The DISM tool will connect to Windows Update to download and replace corrupted files. This step can also take some time, so be patient.
Step 6: Restart your computer
Restart your computer to apply the changes.
After running these tools, a restart ensures that all repairs are properly implemented and your system runs as expected.
After completing these steps, your Windows 11 system should be free from corrupted files and running smoothly. If issues persist, further troubleshooting may be necessary.
