Checking for corrupted files on Windows 11 can seem daunting, but it’s actually a straightforward process. By using built-in tools like the System File Checker (SFC) and the Deployment Imaging Service and Management Tool (DISM), you can easily identify and repair corrupted files. Here’s a simple guide to help you through it. First, open Command Prompt as an administrator, then run the SFC command. If needed, follow up with the DISM command to fix any remaining issues. Let’s break down the process step-by-step to ensure your PC runs smoothly.
How to Check for Corrupted Files in Windows 11
Using these steps, you can effectively locate and repair any corrupted files on your Windows 11 system. This will help maintain the health and performance of your computer.
Step 1: Open Command Prompt as Administrator
Right-click on the Start button and select ‘Windows Terminal (Admin)’ or ‘Command Prompt (Admin)’.
Opening Command Prompt with administrative privileges is crucial because it allows you to run commands that make system-level changes. Without this access, you won’t be able to check for or repair corrupted files.
Step 2: Run the SFC Command
Type sfc /scannow and press Enter.
The System File Checker (SFC) scans your computer for corrupted files and will attempt to repair them if possible. This process might take some time, so be patient. It’s a powerful tool that can fix many common issues with Windows 11.
Step 3: Review the SFC Results
Once the scan is complete, you will see a message indicating whether any issues were found and if they were fixed.
It’s important to read the results carefully. If the SFC tool finds and repairs corrupted files, you’re all set. However, if it can’t fix some files, you’ll need to proceed to the next step with DISM.
Step 4: Run the DISM Command
If SFC couldn’t fix everything, type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
DISM is your backup plan. It repairs the Windows image, which can solve deeper issues that the SFC couldn’t handle. It downloads necessary files from Windows Update, so ensure you’re connected to the internet.
Step 5: Restart Your Computer
After running the commands, restart your computer to apply any changes.
Rebooting allows your system to implement the repairs fully. It’s the final step to ensure that your Windows 11 operates smoothly and efficiently.
After completing these steps, your Windows 11 system should run more smoothly, with any corrupted files repaired. This process not only fixes issues but also prevents future problems, enhancing your computer’s performance.

- Ensure your computer is connected to the internet when using DISM to download necessary files.
