How to Check for Corrupted Files on Windows 11
In this section, we’ll walk you through the steps to check for and repair corrupted files on your Windows 11 PC. By the end, you’ll have a clean and efficient system.
Step 1: Open Command Prompt as Administrator
Hit the Start button, type "cmd," and then right-click on Command Prompt and select "Run as administrator."
Opening Command Prompt with administrative privileges is essential. Without these rights, the commands you run won’t have the necessary permissions to fix system files.
Step 2: Run the SFC Command
Type "sfc /scannow" and press Enter.
The System File Checker will begin scanning your system for corrupted files. This process may take a while, so be patient and let it complete. It will automatically attempt to repair any corrupted files it finds.
Step 3: Check Scan Results
After the scan finishes, you’ll get a report.
If the SFC command finds corrupted files and repairs them, it will inform you. If it can’t fix some files, you might need to use another tool.
Step 4: Run the DISM Command
Type "DISM /Online /Cleanup-Image /RestoreHealth" and press Enter.
The DISM tool will check the Windows image for issues and repair them. This step is crucial if the SFC command didn’t fix all the problems.
Step 5: Restart Your Computer
Once the DISM command completes, restart your computer.
A reboot will ensure that all the repairs take effect and any system file changes are properly initialized.
After completing these steps, your computer should be free of corrupted files, resulting in a more stable and efficient system.
