How to Fix Corrupted System Files in Windows 10

System files on Windows 10 can get corrupted for various reasons. The good news is, you can fix them with a few simple steps. You’ll be using built-in tools like the System File Checker (SFC) and the Deployment Imaging Service and Management Tool (DISM). These tools will scan your system for corrupted files and replace them with the correct versions. Let’s walk through it.

How to Fix Corrupted System Files in Windows 10

In this section, we will use Windows 10’s built-in tools to detect and fix corrupted system files. These steps will guide you through running SFC and DISM to ensure your system files are intact and your computer runs smoothly.

Step 1: Open Command Prompt as Administrator

First, open the Command Prompt with administrative privileges.

To do this, type "cmd" in the search bar. Right-click on ‘Command Prompt’ from the results and select "Run as administrator."

Step 2: Run the System File Checker (SFC) Scan

Type sfc /scannow and press Enter.

This command will scan all protected system files and replace any corrupted files it identifies. This may take some time, so be patient.

Step 3: Analyze SFC Scan Results

After the scan completes, review the results.

If the SFC tool finds corrupted files and repairs them, it will notify you. If it cannot fix some files, you’ll need to move on to the next step.

Step 4: Run the DISM Tool

Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.

This will use Windows Update to provide the necessary files to repair corruption if SFC couldn’t fix everything.

Step 5: Restart Your Computer

Reboot your system to apply the repairs.

A simple restart ensures all the changes take effect and your system runs smoothly with the repaired files.

After completing these steps, your system should be free of corrupted files, and your computer should perform better.
