Hello,

I am looking for assistance with a Windows 11 25H2 servicing/CBS issue that I have been investigating extensively.

The current Windows installation is fully functional for normal use. I would like to repair the existing installation without resetting or reinstalling Windows.

System

  • Windows 11 25H2
  • Edition: Windows 11 Home
  • Architecture: x64
  • Current OS build: 10.0.26200.8875
  • DISM version: 10.0.26100.8737
  • Image version reported by DISM: 10.0.26200.8875
  • Date: September 19, 2026

Recent installed updates:

KB5124007  Security Update     10/09/2026
KB5126052  .NET Update         10/09/2026
KB5101650  Security Update     15/07/2026
KB5071430                       09/12/2025
KB5054156                       09/12/2025

1. Original problem

Windows' built-in repair/reinstall function ("Reinstall now" / Windows Update repair) fails with:

0xC190011F

I also attempted an in-place repair using an official Windows 11 25H2 ISO, but Setup rolled back at approximately 30%.

I am not looking for a reset/reinstall solution. I want to repair the existing Windows installation if possible.

2. DISM / SFC results

I ran:

DISM /Online /Cleanup-Image /RestoreHealth

Result: successful.

I also ran:

DISM /Online /Cleanup-Image /ScanHealth

Result:

No component store corruption detected.

However, CBS clearly reports package-resolution failures during servicing.

SFC initially repaired some corrupted files, but subsequently:

sfc /scannow

can fail with:

Windows Resource Protection could not start the repair service.

TrustedInstaller and the other relevant services are running.

3. CBS failure involving Recall

During the failed installation of the current LCU, CBS reports:

Failed to populate package overrides
HRESULT = 0x80070002 - ERROR_FILE_NOT_FOUND

Failed to translate parsed manifest into package/update objects

Failed to initialize package:
UserExperience-Recall-Package~31bf3856ad364e35~amd64~~10.0.26100.9457

It then fails to resolve the package and its parent/child relationships, ultimately preventing installation of:

Package_for_RollupFix...26100.9457

The same problem previously occurred with the July LCU:

UserExperience-Recall-Package~31bf3856ad364e35~amd64~~10.0.26100.8875

Therefore, this is reproducible across two different LCUs.

4. The Recall files are physically present

The Recall package files are not simply missing.

For version 26100.8875, the following files exist in:

C:\Windows\Servicing\Packages

UserExperience-Recall-Package~31bf3856ad364e35~amd64~~10.0.26100.8875.mum
UserExperience-Recall-Package~31bf3856ad364e35~amd64~~10.0.26100.8875.cat

I verified their SHA-256 hashes against the official Microsoft KB content.

MUM

164A60AEBEDD6686F998A8A59A95E906FB6FBA979F5A1BF0791C190FBB081CF9

CAT

62F5E67AB973A2E2F3A78CC1643D5E136EABE91A372C2B4AD570B6B3CE1544E4

The files are identical to those contained in the official Microsoft KB5101650 package.

Nevertheless:

DISM /Online /Get-PackageInfo /PackagePath:<Recall.mum>

fails with:

0x80070002

And:

DISM /Online /Get-Packages | findstr /i Recall

returns nothing.

5. KB5129195 investigation

I downloaded the official Microsoft Update Catalog package:

Windows11.0-KB5129195-x64_ed361878ec2b56a7dfdb8f256565263a7fdc8eaa.msu

Size:

4,639,422,594 bytes

I attempted the normal DISM installation:

DISM /Online /Add-Package /PackagePath:"D:\DL\windows11.0-kb5129195-x64_ed361878ec2b56a7dfdb8f256565263a7fdc8eaa.msu"

The MSU expands successfully, but installation fails at approximately 1% with:

0x80070002
The specified file was not found.

DISM identifies the package as:

Package_for_RollupFix~~amd64~~26100.9457.1.0

CBS then identifies the Recall package as the failing dependency.

I extracted the WIM contained in the MSU and confirmed that it contains:

UserExperience-Recall-Package~31bf3856ad364e35~amd64~~10.0.26100.9457.cat
UserExperience-Recall-Package~31bf3856ad364e35~amd64~~10.0.26100.9457.mum

The 9457 MUM contains this parent:

<parent integrate="delegate">
  <assemblyIdentity
      name="Microsoft-Windows-Foundation-Package"
      version="10.0.26100.9457"
      processorArchitecture="amd64"
      language="neutral"
      buildType="release"
      publicKeyToken="31bf3856ad364e35" />
</parent>

It also contains:

<assemblyIdentity
    name="UserExperience-AIX-Package"
    version="10.0.26100.9457"
    processorArchitecture="amd64"
    language="neutral"
    buildType="release"
    publicKeyToken="31bf3856ad364e35" />

However, the KB5129195 WIM does not contain:

Microsoft-Windows-Foundation-Package 10.0.26100.9457

6. Local Foundation package

The only Foundation package physically present in:

C:\Windows\Servicing\Packages

is:

Microsoft-Windows-Foundation-Package~31bf3856ad364e35~amd64~~10.0.26100.1.cat
Microsoft-Windows-Foundation-Package~31bf3856ad364e35~amd64~~10.0.26100.1.mum

There is no local:

Microsoft-Windows-Foundation-Package 26100.8875
Microsoft-Windows-Foundation-Package 26100.9457

I do not know whether this is expected behavior for Windows 11 25H2 or indicates a servicing inconsistency.

I would specifically like Microsoft to clarify this point.

7. KB5043080 checkpoint

I also downloaded the official checkpoint package required by KB5129195:

Windows11.0-KB5043080-x64_953449672073f8fb99badb4cc6d5d7849b9c83e8.msu

Its contents include:

DesktopDeployment.cab
DesktopDeployment_x86.cab
SSU-26100.1738-x64.cab
Windows11.0-KB5043080-x64.wim
onepackage.AggregatedMetadata.cab
wsusscan.cab

Attempting to install it with DISM:

DISM /Online /Add-Package /PackagePath:"D:\DL\windows11.0-kb5043080-x64_953449672073f8fb99badb4cc6d5d7849b9c83e8.msu"

failed during expansion with:

0x80070228
Error 552
The ACL passed does not contain the minimum required information.

Trying WUSA resulted in:

The update is not applicable to your computer.

I therefore did not force the checkpoint installation.

8. Another independent CBS inconsistency: OpenSSH

There is also a separate package-store problem involving OpenSSH.

Attempting to uninstall KB5101650 fails with:

0x800F0825
CBS_E_CANNOT_REMOVE

CBS reports:

OpenSSH.Server~~~~0.0.1.0 must be uninstalled first.
The previous LCU version is not complete.

OpenSSH.Server... RTM version is missing.

Failed to re-install supersed versions for Package_for_RollupFix...26100.8655

Current package enumeration shows:

OpenSSH-Client 1742     Intermediate
OpenSSH-Client 8655     Superseded
OpenSSH-Client 8875     Installed

OpenSSH-Server 1742     Intermediate
OpenSSH-Server 8875     Installed

There is no OpenSSH Server 8655 package.

The OpenSSH Server 8875 .mum is present and:

DISM /Online /Get-PackageInfo

recognizes it as installed.

However, attempting to remove it directly with DISM:

DISM /Online /Remove-Package /PackagePath:"C:\Windows\Servicing\Packages\OpenSSH-Server-Package...8875.mum"

fails with:

0x80070490
Element not found

CBS then reports the following missing dependency:

Failed to resolve package:

Microsoft-OneCore-OpenSSH-ServerOnly-AllowGroups-Package
~31bf3856ad364e35~amd64~~10.0.26100.7705

Failed to resolve child of Package:
OpenSSH-Server-Package...8875

Failed to add package:
OpenSSH-Server-Package...8875

Failed to plan execution

I verified that the AllowGroups package is not physically present in:

C:\Windows\Servicing\Packages

I also searched:

C:\Windows\SoftwareDistribution\Download
C:\Windows\WinSxS\Manifests

The OpenSSH 7705 manifests/components exist, but I cannot find the AllowGroups package/component corresponding to the missing dependency.

9. Component Store health contradiction

This is the main issue I would like Microsoft to explain.

DISM /Online /Cleanup-Image /ScanHealth

reports:

No component store corruption detected.

And:

DISM /Online /Cleanup-Image /RestoreHealth

completes successfully.

Yet CBS cannot resolve existing packages/dependencies and repeatedly returns:

0x80070002
ERROR_FILE_NOT_FOUND

and:

0x80070490
ERROR_NOT_FOUND

Cumulative update installation fails.

The Windows repair installation also fails with:

0xC190011F

10. Other repair attempts

I have also:

  • Reset/renamed the Windows Update SoftwareDistribution cache.
  • Attempted an official Windows 11 25H2 in-place repair.
  • The ISO was older than the installed system:
    • ISO: 26200.8037
    • Installed OS: 26200.8875
  • Setup rolled back at approximately 30%.
  • Setup/CBS logs show: 
      ICbsSession::Finalize failed
  0x800706be
  • CBS showed package-store enumeration fallback.
  • TiWorker crashed/restarted during servicing.

I also have a current full Veeam backup of the system.

11. What I am asking Microsoft

At this point I would like assistance from someone familiar with CBS / servicing stack internals, rather than the standard recommendation to run DISM and SFC, since those have already been tested.

Specifically:

  1. Is there a supported Microsoft procedure to rebuild/reset the CBS package metadata/catalog without reinstalling Windows?
  2. If not, what is the supported way to repair these package/dependency registrations?
  3. Why does CBS attempt to resolve: 
       UserExperience-Recall-Package 26100.9457
    whose MUM declares: 
       Microsoft-Windows-Foundation-Package 26100.9457
    when that Foundation package is neither present locally nor contained in the KB5129195 WIM?
  4. Is this expected behavior for Windows 11 25H2, or does it indicate an incomplete/damaged servicing baseline?
  5. How should the missing: 
       Microsoft-OneCore-OpenSSH-ServerOnly-AllowGroups-Package
   26100.7705
    dependency be restored?
  6. Is there a Microsoft-supported offline CBS repair procedure from WinRE that can reconstruct/reconcile the package store without resetting Windows?
  7. Is there a specific servicing stack, baseline package, checkpoint, or other Microsoft package that should be installed/repaired to restore the correct CBS state?
  8. Can Microsoft provide the correct source/package(s) required to repair these dependencies?

I am willing to perform an offline repair if there is a documented procedure. I would strongly prefer to repair the existing Windows installation rather than reset or reinstall Windows.

I can provide the relevant:

  • CBS.log
  • DISM.log
  • setupact.log
  • setuperr.log
  • SetupDiag output

if required.

Thank you.

Please download fix.reg.txt

Rename it to fix.reg.

Double-click fix.reg and run it. Click Yes to confirm.

Run:

dism /online /get-capabilities /format:table

Post the output.

Please edit your question and add the missing info. Most of the data (in code block) seems to be missing.

I also attempted an in-place repair using an official Windows 11 25H2 ISO, but Setup rolled back at approximately 30%.

Also, upload a zipped copy of the following setup log file:

C:\$WINDOWS.~BT\Sources\Panther\setupact.log

Note: C:\$WINDOWS.~BT is a hidden folder. To access it, press Win + R, type C:\$WINDOWS.~BT and click OK.

    Thank you. I have edited the question and restored the missing information from the code blocks.
    The full troubleshooting history and the relevant CBS/DISM findings are now included.
    I will also upload a ZIP copy of: ```text C:$WINDOWS.~BT\Sources\Panther\setupact.log

    The in-place repair was performed using an official Windows 11 25H2 ISO. Setup rolled back at approximately 30%, which is why I am including the setupact.log from that attempt.

    The system is currently running normally; the problem is specifically with the Windows servicing/component store, cumulative update installation, and the in-place repair.

    I have not marked the problem as solved.

    The requested C:\$WINDOWS.~BT\Sources\Panther\setupact.log is no longer available because the failed setup attempt has already been rolled back and Windows has cleaned up $WINDOWS.~BT.

    However, I still have the corresponding setupact.log from the same failed in-place repair attempt: C:\Windows\Panther\NewOs\Panther\setupact.log

    I try to uploaded this file as a ZIP instead, but zip is not a good extension for this post so a link here to download it:
