How to repair corrupted files on Windows 10?

To repair corrupted files on Windows 11, that includes a suite of powerful, command-line utilities designed to diagnose and fix different types of corruption. The two primary tools are the System File Checker (SFC) and the Deployment Image Servicing and Management (DISM) tool. Often, you'll need to use them in a specific order to achieve the best results.

1. Check the System Image First (DISM):

Open Command Prompt or PowerShell as an administrator.

First, run a health check:

cmd

DISM /Online /Cleanup-Image /CheckHealth

Next, perform a more thorough scan:

cmd

DISM /Online /Cleanup-Image /ScanHealth

Finally, if any issues are found, run the repair command:

cmd

DISM /Online /Cleanup-Image /RestoreHealth

This can take some time if you are going to repair corrupted files on Windows 11, potentially up to an hour or more, depending on your system.

2. Repair System Files Second (SFC):

After the DISM repair is complete, run the SFC tool:

cmd

sfc /scannow

3. Check Your Disk (Chkdsk):

If you suspect the corruption is due to underlying hard drive errors, you can use the Check Disk utility. The /r parameter finds bad sectors and recovers readable information.

To check and repair the C: drive, use the command:

cmd

chkdsk C: /r
