My DISM had a problem

Question

_Quang@Cyber 🤖 : dism /Online /Cleanup-Image /RestoreHealth

Deployment Image Servicing and Management tool

Version: 10.0.26100.5582

Image Version: 10.0.26200.5710

[==========================100.0%==========================]

Error: 0x800f0915

The repair content could not be found anywhere.

Check the internet connectivity or use the "Source" option to specify the location of the files that are required to restore the image. For more information on specifying a source location, see https://go.microsoft.com/fwlink/?LinkId=243077.

The DISM log file can be found at C:\Windows\Logs\DISM\dism.log

Answer 1

I think this might be a simple but subtle issue. Check your Windows Security Center settings: cfg Control Flow Protection. You need to set it to "On by default" instead of "Default Mode (On)." This setting is in "Exploit Prevention Settings" within "App & Browser Control."

Hello, good morning! How are you?

I'm having almost exactly the same problem, and regarding:

"Your log information is very helpful. It shows that your DISM tool version (10.0.26100.5582) is older than the system image version (10.0.26200.5710) you're trying to repair."

The problem is that I haven't found any ISO with build 10.0.26200.5710 or at least 10.0.26200.xx.

The problem is that I don't have access to the system to repair it from within because I have a green screen, it won't boot, and from the Windows Recovery Environment, I have almost the same problem as user Quang. using:

DISM /Image:I:\ /Cleanup-Image /RestoreHealth /Source:WIM:M:\sources\install.wim:6 /LimitAccess

\install.wim:6 WIN11 PRO in my case and The paths are verified...

"Error: 0x800f0915

The repair content was not found anywhere.

Check your internet access or use the "Source" option to specify the location of the files needed to restore the image. For more information on how to specify a source location, see https://go.microsoft.com/fwlink/?LinkId=243077."

Thanks!

Hello, Quang

Welcome to Microsoft Q&A.

Thank you very much for providing the command line output. The error you encountered — Error: 0x800f0915 — is a relatively common issue when running DISM repairs. The core message of this error is: “The source files could not be found.”

Your log information is very helpful. It shows that your DISM tool version (10.0.26100.5582) is older than the system image version (10.0.26200.5710) you’re trying to repair.

When the DISM tool version is older than the target system version, it fails to retrieve the correct repair files from the Windows Update servers and therefore reports “source files not found” (Error: 0x800f0915). To resolve this, you’ll need to provide a valid repair source that exactly matches your system version (10.0.26200.5710).

Here are some recommended solutions. Please follow them in order:

Use Matching Windows Installation Media as Repair Source

This is the most recommended and reliable method. You need to download an ISO file that matches your current system version and use it as a local source.

1. Download the correct ISO file:

• Visit: https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewiso
• Sign in with your Insider account.
• On the download page, look for a version that closely matches Build 26200 (e.g., Canary or Dev Channel with Build 26200 or slightly newer).

2. Mount the ISO file:

• Once downloaded, right-click the .iso file and choose Mount.
• Windows will assign it a new drive letter (e.g., E:).

3. Run the DISM command with source specified:

• Open Command Prompt or Windows Terminal as Administrator.
• Check whether the ISO contains install.wim or install.esd by opening the sources folder inside the mounted ISO drive.

Depending on the file type, run one of the following commands (replace E: with your actual mounted drive letter):

• If you found install.wim:

DISM /Online /Cleanup-Image /RestoreHealth /Source:WIM:E:\sources\install.wim:1 /LimitAccess

• If you found install.esd (common in official downloads):

DISM /Online /Cleanup-Image /RestoreHealth /Source:ESD:E:\sources\install.esd:1 /LimitAccess

Explanation of the command:

/Source: specifies the repair source path.

WIM: or ESD: tells DISM the image format.

:1 refers to the image index — usually index 1 contains Windows Pro or Home editions.

/LimitAccess forces DISM to use only the local source and not check Windows Update.

Perform an In-Place Upgrade (Repair Install)

Disclaimer: Let’s try performing an in-place install or in-place upgrade which will refresh your Windows files and operating system without removing files or applications. That being said, we always recommend that if you have important data, you should back it up before making large system changes. 

If DISM fails even with a correct source, or you want a more comprehensive fix, an in-place upgrade is the best choice. This method reinstalls and repairs all system files while preserving your personal files, settings, and apps.

Steps:

1. Download and mount the correct ISO file as in the previous method.
2. Open the mounted drive and double-click setup.exe.
3. In the installation wizard, select “Change how Windows Setup downloads updates.”
4. Make sure “Keep personal files and apps” is selected.
   If this option is greyed out, your ISO version does not match your installed system — download the correct one.
5. Proceed with the installation. Your computer will reboot several times and complete the repair.

You might be tempted to run sfc /scannow first — however, SFC relies on the component store maintained by DISM. If that store is already corrupted (as it appears here), SFC will also fail. That’s why we must fix DISM first.

If you encounter any issues during these steps or receive new error messages, feel free to reply with the details. We’ll be happy to continue assisting you.
