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.

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.
