Last Updated on May 31, 2024 by Arnav Sharma

When your Windows 10 system encounters issues such as corruption or missing files, performing a DISM offline repair can be an effective solution. This process uses the Deployment Image Servicing and Management (DISM) tool, which can help fix system problems that other tools might not resolve. Here’s a comprehensive guide to running a DISM offline repair on Windows 10.

Understanding DISM

DISM stands for Deployment Image Servicing and Management. It is a command-line tool provided by Microsoft for servicing and preparing Windows images, including the Windows Recovery Environment, Windows Setup, and Windows PE (WinPE).

The primary purpose of DISM is to repair and service Windows images. It can help fix issues such as corrupt system files and failed Windows updates.

Using DISM offline means running the tool when your system is not booted into the standard operating mode, also known as offline mode. This can be particularly useful when the operating system is too damaged to function properly.

Preparing for DISM Offline Repair

To perform an offline repair, you’ll need a USB flash drive or a DVD with the Windows 10 installation files. This media allows you to boot into a recovery environment and access the necessary tools.

Performing the DISM Offline Repair

Boot into Recovery Environment

1. Boot your computer using the Windows 10 installation media.
2. Access the command prompt by selecting “Repair your computer” > “Troubleshoot” > “Advanced options” > “Command Prompt”.

Use DISM Command

3. Identify the drive letter assigned to your Windows installation. This is typically C:, but it may vary in the recovery environment.
4. Type the following command to check the health of your system image: dism /image:C:\ /cleanup-image /scanhealth Replace C: with the appropriate drive letter if necessary.
5. To repair the image, use the following command: dism /image:C:\ /cleanup-image /restorehealth /source:WIM:X:\sources\install.wim:1 /limitaccess Replace X: with the drive letter of your installation media.

Complete the Repair

6. After the command completes, reboot your system. Your Windows 10 installation should now be repaired.

Additional Tips

After running the DISM tool, it’s a good practice to run the System File Checker (SFC) to ensure all system files are intact. You can do this by typing:

sfc /scannow

Using the ISO File

If you don’t have a physical installation media, you can mount an ISO file and use it as the source to repair the offline Windows 10 image.

Safe Mode

If you can boot into Windows 10 but still face issues, you can also try running the DISM tool in Safe Mode.
