Use the DISM command tool to repair a Windows 10 image | Windows Central

Windows Help · 2025-11-05T18:14:51Z

Deployment Image Servicing and Management (DISM) is a command-line tool built into Windows 10 that allows network administrators to prepare, modify, and repair system images, including Windows Recovery Environment, Windows Setup, and Windows PE (WinPE). However, you can also use the tool with the local recovery image to fix most system problems.

When you try to fix a specific error, figure out why the computer stopped booting correctly, or resolve performance problems, the System File Checker (SFC) is one of the best tools to replace missing or corrupted system files using the recovery image. The only caveat with this approach is that if one or more system files in the local image are damaged, the SFC command won't work. In this scenario, you can use the "install.wim" image file with DISM to repair the image and then use the SFC tool to fix the setup without reinstalling the operating system.

In this how-to guide, I will show you how, in 2025 and beyond, the DISM and SFC are the best tools for restoring a computer from a broken to a healthy working state without reinstallation.

How to use DISM to repair image of Windows 10

The DISM command tool includes multiple features to repair a system image, including "CheckHealth," "ScanHealth," and "RestoreHealth," and you want to use them in that order. Also, depending on the issue, you can use the "RestoreHealth" option to fix the locally available image using different source files.

DISM command with CheckHealth option

The "CheckHealth" option with the DISM determines any corruptions inside the local Windows 10 image. However, this option does not perform any sort of repair.

To check the image of Windows 10 for issues with DISM, use these steps:

Once you complete the steps, the DISM tool will run and verify any data corruption that may require fixing inside the local image.

DISM command with ScanHealth option

The "ScanHealth" option performs a more advanced scan to find out whether the image has any issues.

To check image problems with the "ScanHealth" option, use these steps:

Open Start.
Search for Command Prompt, right-click the top result, and select the Run as administrator option.
Type the following command to perform an advanced DISM scan and press Enter: DISM /Online /Cleanup-Image /ScanHealth

After completing the steps, the scan may take some time to check whether the image needs fixing.

DISM command with RestoreHealth option

If the system image has problems, the "RestoreHealth" option scans and repairs common issues automatically.

To repair Windows 10 local image problems with DISM, use these steps:

Open Start.
Search for Command Prompt, right-click the top result, and select the Run as administrator option.
Type the following command to repair the image and press Enter: DISM /Online /Cleanup-Image /RestoreHealth

Quick note: It's normal if the command appears stuck. After a few moments, the process will be completed successfully.

Once you complete the steps, the Deployment Image Servicing and Management tool will connect to the "Windows Update" servers to download and replace damaged files (if applicable).

Fix problems with DISM using install.wim image

The Deployment Image Servicing and Management commands typically don't cause issues. However, if the tool finds problems replacing the damaged files or the computer doesn't have an internet connection, you can use another image using the "Source" option. Usually, you can use an "install.wim" or "install.esd" file from another device, install media, or ISO file. You only need to ensure the files match the version, edition, and language of the version you are trying to fix.

Download Windows 10 ISO file

If you need another file source, use the Media Creation Tool to download a fresh copy of Windows 10.

To download the ISO file of Windows 10, use these steps:

Open this Microsoft support website.
Click the Download Now button.
Double-click the MediaCreationTool_xxxx.exe file to launch the setup.

After you complete the steps, continue with the DISM tool using the "Source" option to repair the image locally stored on the computer.

Fix Windows 10 recovery image

To run the Deployment Image Servicing and Management tool with an alternate source (install.wim) image, use these steps:

Open Start.
Search for Command Prompt, right-click the top result, and select the Run as administrator option.
Type the following command to repair the image and press Enter: DISM /Online /Cleanup-Image /RestoreHealth /Source:E:\Sources\install.wim

In the command, replace "E" with the mount point drive letter on File Explorer.

(Optional) Type the following command to limit the use of Windows Update and press Enter: DISM /Online /Cleanup-Image /RestoreHealth /Source:G\Sources\install.wim /LimitAccess
(Optional) Type the following variant of the previous command to accomplish the same task and press Enter: DISM /Online /Cleanup-Image /RestoreHealth /Source:wim:G:\Sources\install.wim:1 /LimitAccess

In the command, change "G:\Sources," for the path to the "install.wim" file.

Once you complete the steps, the command will scan and repair the problems using the "install.wim" file you specified as the alternative source.

Fix problems with DISM using ESD image

In case you have an encrypted "install.esd" image, it's possible to use that image to repair the damaged system files on Windows 10.

To use DISM with an "install.esd" image file as the source to repair Windows 10, use these steps:

Open Start.
Search for Command Prompt, right-click the top result, and select the Run as administrator option.
Type the following command to repair the image with an "install.esd" file and press Enter: DISM /Online /Cleanup-Image /RestoreHealth /Source:C:\ESD\Windows\sources\install.esd

In the command, change "C:\ESD\Windows\sources" with the path to the location of the ".esd" file (if different).

(Optional) Type the following command to limit the use of Windows Update and press Enter: DISM /Online /Cleanup-Image /RestoreHealth /Source:C:\ESD\Windows\sources\install.esd /LimitAccess
(Optional) Type the following variant of the previous command to accomplish the same task and press Enter: DISM /Online /Cleanup-Image /RestoreHealth /Source:esd:C:\ESD\Windows\sources\install.esd:1 /LimitAccess
(Optional) Type the following command to use an install.esd file located in another drive and press Enter: DISM /Online /Cleanup-Image /RestoreHealth /Source:E:\Sources\install.esd

In the command, replace "E:\Sources" with the path to the location of the "install.esd" file.

After you complete the steps, the tool will repair the damaged files using the files included in the "install.esd" image.

Troubleshooting common errors

If the RestoreHealth command fails, depending on the error, you can try these fixes:

Error 0x800f081f: The source files could not be found – You can resolve this error by running the DISM /Online /Cleanup-Image /RestoreHealth /Source:wim:D:\sources\install.wim:1 /LimitAccess command.
Error 87: The parameter is incorrect – Check the command for typos and re-try it. Commands are case-insensitive, but spaces must be exact.
DISM stuck at 20%, 40%, or 80% – Restart the computer and try again. It can also help run the chkdsk C: /f /r /x command to check for disk errors. However, before taking any actions, consider that sometimes, if the command appears stuck, it could also mean the tool is busy repairing the system.
Error 0x800f0906: DISM fails to download files – This error indicates that the tool is having issues downloading files from Windows Update. In this case, ensure your internet connection is stable. Try using a local Windows installation source using the above steps.

You can also examine the command-line tool log file located at C:\WINDOWS\Logs\DISM\dism.log to find clues to determine the exact problem.

If you're unable to get this DISM command working and the current setup has problems, you may want to consider resetting the computer to the factory default with the Reset this PC feature or by performing a clean installation of Windows 10.

How to run SFC to repair problems on Windows 10

The above steps are meant to repair issues with the system image, not the problems with the installation of Windows 10. After restoring the image to a healthy state, you can use the System File Checker command tool to repair the current setup of Windows 10.

To use the SFC command tool to repair system problems, use these steps:

Open Start.
Search for Command Prompt, right-click the top result, and select the Run as administrator option.
Type the following command to repair the installation and press Enter: SFC /scannow

Quick tip: If errors are found, you may want to run the command around three times to ensure that everything was fixed correctly.

Once you complete the steps, the System File Checker tool will repair the system files using the local image files, and the log files will be saved on "%windir%/Logs/CBS/CBS.log" and "%windir%\Logs\DISM\dism.log," which you can view to get more details about the process.

You can use these instructions to learn more ways to use the SFC tool to fix problems on Windows 10.
