Finding corrupted files on Windows 10 isn’t as scary as it sounds. With just a few simple steps, you can identify and fix these pesky files that may be causing your system to act up. By using built-in tools like the System File Checker (SFC) and Deployment Imaging Service and Management Tool (DISM), you can quickly get your computer back on track.
How to Find Corrupted Files Windows 10
In this guide, we’ll use the System File Checker (SFC) and Deployment Imaging Service and Management Tool (DISM) to locate and repair corrupted files on your Windows 10 system. These tools are reliable and come pre-installed with Windows, so you don’t need to download anything extra.
Step 1: Open Command Prompt as Administrator
Open Command Prompt with admin rights to access all needed system tools.
To do this, click on the Start button, type "cmd" in the search box, right-click on "Command Prompt," and select "Run as administrator." A prompt will ask for permission; just click "Yes."
Step 2: Run System File Checker (SFC)
Run the SFC command to scan for and repair corrupted files.
Type sfc /scannow
and hit Enter. This command will start scanning your system files for any issues and attempt to fix them automatically. The scan may take some time, so be patient.
Step 3: Check the SFC Results
Review the SFC results to see what actions were taken.
Once the scan is complete, you’ll see a message indicating whether any corrupt files were found and if they were fixed. If issues were detected but not fixed, you’ll need to move on to the next step.
Step 4: Run DISM Tool
Use the DISM tool to fix any remaining issues that SFC couldn’t handle.
Type DISM /Online /Cleanup-Image /RestoreHealth
in the Command Prompt and press Enter. This tool will connect to Windows Update to download and replace damaged files. This process can also take some time, so be patient.
Step 5: Run SFC Again
Run the SFC command again to ensure all issues are resolved.
After DISM has completed its task, it’s a good idea to run sfc /scannow
one more time to confirm that all corrupted files have been fixed.
After following these steps, your Windows 10 system should be free of corrupted files and running smoothly.
