Ensuring your Windows 11 files aren’t corrupted is crucial for maintaining a smooth and efficient computer. By following a few easy steps, you can quickly scan and fix any corrupted files lurking in your system. This process involves using built-in tools like the System File Checker and the Deployment Imaging Service and Management Tool. Ready to dive in? Let’s get started!
How to Check for Corrupted Files in Windows 11
In this section, we’ll walk through a step-by-step guide on how to identify and repair corrupted files on your Windows 11 device. This process will help keep your system running smoothly and efficiently.
Step 1: Open Command Prompt as Administrator
The first step is to open the Command Prompt with administrator privileges.
Right-click on the Start button, select “Windows Terminal (Admin)”, and then click “Yes” to the User Account Control prompt that appears. This will open the Command Prompt with elevated privileges, which is necessary for the tools we’ll be using.
Step 2: Run the System File Checker (SFC) Scan
Next, we’ll use the System File Checker tool to scan for and repair corrupted files.
In the Command Prompt window, type sfc /scannow and press Enter. This command will start a system scan, and it may take some time to complete. Let the scan run uninterrupted to ensure it thoroughly checks all system files.
Step 3: Review the Scan Results
After the scan completes, you need to check the results to see what was found and fixed.
The Command Prompt will display a message indicating whether or not any corrupted files were found and repaired. If files were fixed, you might need to restart your computer to complete the process.
Step 4: Run the DISM Tool
If the SFC scan didn’t fix the problem, use the Deployment Imaging Service and Management Tool (DISM) for a more comprehensive system repair.
In the Command Prompt, type DISM /Online /Cleanup-Image /RestoreHealth and press Enter. This will start the DISM tool, which can take a while to run. Be patient and do not interrupt the process.
Step 5: Restart Your Computer
Finally, restart your computer to apply any changes and complete the repair process.
A restart ensures that all repairs are fully implemented and any lingering issues are resolved. Once your computer boots back up, you should have a system free of corrupted files.
Once you’ve followed these steps, your system should be free of corrupted files, and you should notice an improvement in performance and stability.
Tips for Checking for Corrupted Files in Windows 11
- Tip 1: Run the System File Checker regularly, especially after installing new software or updates.
- Tip 2: Keep your system updated to minimize risks of file corruption.
- Tip 3: Always run the Command Prompt as an administrator to ensure you have the necessary permissions.

Frequently Asked Questions
What if the SFC scan finds but cannot fix corrupted files?
If the SFC scan finds corrupted files but cannot fix them, use the DISM tool to repair the system image, then run the SFC scan again.
How long does an SFC scan take?
An SFC scan typically takes 10-30 minutes, depending on the size of your system and the number of files it needs to check.
Can I use my computer while running an SFC or DISM scan?
It’s best to avoid using your computer during these scans to prevent any interruptions that could affect the scan results.
What causes file corruption in Windows 11?
File corruption can be caused by various factors, including software conflicts, malware, sudden power outages, and hardware failures.
Do I need internet access to run the SFC and DISM scans?
No, the SFC scan does not require internet access, but the DISM tool may need internet access to download replacement files if they are not available locally.
