How to Repair Windows 11 and 10 Image with DISM Command Tool

Encountering issues with Windows 11 can be frustrating, especially when they stem from corrupted system files. The Deployment Image Servicing and Management (DISM) tool offers a robust solution for diagnosing and repairing these problems. This guide will walk you through the process of using DISM and the System File Checker (SFC) to restore your Windows 11 system to optimal performance.

Preliminary Steps: Disk Check

Before initiating the DISM repair process, it is crucial to perform a disk check to identify and rectify any file system issues. Skipping this step could result in the persistence of file corruption, negating the benefits of subsequent repairs.

1) Open Command Prompt as Administrator:

Click the Start button, search for Command Prompt, right-click it, and select Run as administrator. Or in Windows 11, right-click on the Start button and select Terminal (Admin). This is necessary for both the DISM and SFC commands.

2) Execute the Disk Check:

In the Command Prompt, type chkdsk c: /f /r and press Enter. Confirm the operation by typing Y and pressing Enter again. This schedules the disk check for the next system restart.

3) Allow the Check to Complete Uninterrupted:

Upon restarting, you’ll have the option to bypass the disk check. If immediate access to Windows is not urgent, avoid skipping this step. Interruptions can cause significant file system damage.

The DISM tool scans for and corrects issues within the system files. It’s particularly useful for fixing operating system errors without affecting personal data.

1) Verify System Health:

Input DISM /Online /Cleanup-Image /CheckHealth in the Command Prompt and press Enter. This command performs a preliminary check for corruption signatures.

2) Conduct an In-depth Scan:

For a thorough examination, use DISM /Online /Cleanup-Image /ScanHealth. This process may take some time but will pinpoint specific corrupted files.

3) Initiate Repair:

To repair the identified issues, enter DISM /Online /Cleanup-Image /RestoreHealth and press Enter. Despite possible pauses in progress indication, the tool works in the background to download and replace damaged files.

Finalizing with a System File Check (SFC)

To address problems related to Windows setup or to ensure the DISM process has resolved the issues, use the System File Checker.

Run SFC Scan:

With Command Prompt still open as administrator, type SFC /scannow and press Enter. This scans all protected system files and repairs them using the now-repaired local image files. If errors are detected, it may be beneficial to run the scan multiple times for comprehensive repair.


Utilizing the DISM tool and System File Checker is a powerful method for addressing and repairing Windows 11 issues related to corrupted system files. By following the outlined steps, you can restore your system’s functionality and performance. Regular maintenance, including disk checks and system scans, can preemptively avoid many common problems, ensuring a smoother Windows experience
