Common corruption errors

Windows updates may fail to install if there are corruption errors. You can check the Setup event log for errors. The following table lists the possible error codes for Windows Update for your reference:

For example, an update might not install if a system file is damaged. The DISM may help you fix some Windows corruption errors.

Using DISM to repair Windows Update corruptions

Note

The solution mentioned in this section applies to Modern Windows versions like Windows 11, Windows 10, Windows Server 2016, or later.

To resolve Windows Update corruptions and address update installation failures, use the DISM tool. Then, install the Windows Update.

  1. Open an elevated command prompt. To do this, open the Start menu, type Command Prompt, right-click Command Prompt, and then select Run as administrator. If you're prompted for an administrator password or for a confirmation, type the password, or select Yes.

  2. Type the following command, and then press Enter. It may take several minutes for the command operation to be completed.

    DISM.exe /Online /Cleanup-image /Restorehealth

    Important

    DISM repair works best when you connect to Microsoft Update servers to fetch missing or corrupted files. When you use the proceeding command, DISM gets the files needed to fix any corruptions from Windows Update. However, if your computer can't connect to Windows Update, you can alternatively use a working Windows installation as the repair source, or you can use files from a Windows folder on a network or from a USB or DVD. Instead, use this command:

    DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:\\<servername>\c$\winsxs /LimitAccess

    Note

    Replace <servername> with the computer name of the computer you are using as a repair source. The repair source computer must be running the same operating system version. For more information about using the DISM tool to repair Windows, reference Repair a Windows Image. If the scan result is "The restore operation completed successfully", go to the next step. If not, try to analyze the CBS.log file and fix errors.

  3. Type the sfc /scannow command and press Enter. It may take several minutes for the command operation to be completed.

  4. Close the command prompt, and then run Windows Update again.

DISM creates a log file (%windir%\Logs\CBS\CBS.log) that captures any issues that the tool found or fixed. %windir% is the folder in which Windows is installed. For example, the %windir% folder is C:\Windows.

How does DISM Repair work?

DISM is a command-line tool that is used to service and repair Windows images, including the Windows Recovery Environment, Windows Setup, and Windows PE (WinPE). It can also be used to repair the local Windows image on your computer.

To give you a better understanding, here's a summary of the resources that the DISM tool checks for integrity:

  • Files that are located in the following directories:
    • %SYSTEMROOT%\Servicing\Packages
    • %SYSTEMROOT%\WinSxS\Manifests
  • Registry data that's located under the following registry subkeys:
    • HKEY_LOCAL_MACHINE\Components
    • HKEY_LOCAL_MACHINE\Schema
    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Component Based Servicing

This list may be updated at any time. When the DISM detects incorrect manifests, Cabinets, or registry data, it may replace the incorrect data with a corrected version.

Logging

The DISM tool creates a log file that captures any issues that the tool found or fixed. The log file is located here:

  • %SYSTEMROOT%\Logs\CBS\CBS.log
  • %SYSTEMROOT%\Logs\CBS\CBS.persist.log

Advanced guide to fix CBS corruption manually using DISM utility

Step 1: Analyze the CBS.log file

After running the DISM commands, go to %WinDir%\Logs\CBS\CBS.log to view the results. The log file provides a summary of the scan and details of any errors found.

Here's an example of the log summary:

Checking System Update Readiness.

Summary:
Operation: Detect and Repair

Last Successful Step: Remove staged packages completes.
Total Detected Corruption: 2
    CBS Manifest Corruption: 2
    CBS Metadata Corruption: 0
    CSI Manifest Corruption: 0
    CSI Metadata Corruption: 0
    CSI Payload Corruption: 0
Total Repaired Corruption: 1
    CBS Manifest Repaired: 1
    CSI Manifest Repaired: 0
    CSI Payload Repaired: 0
    CSI Store Metadata refreshed: False
Staged Packages:
    CBS Staged packages: 0
    CBS Staged packages removed: 0

Note

CSI Payload Corruption: This indicates that the payload file EnterpriseModernAppMgmtCSP.dll is corrupt.

CBS MUM Missing: A required MUM file is missing from the package (Microsoft-Windows-Client-Features-Package).

CSI Manifest Corruption: There were two instances of manifest corruption. One was fixed (wow64_microsoft-windows-audio-mmecore-acm), and the other (wow64_microsoft-windows-audio-volumecontrol) remains corrupt.

Step 2: Download the missing files

  1. Identify the missing or corrupted files.

    Review the CBS.log file to identify the missing or corrupted files. For example:

    (p) CSI Payload Corrupt (n) amd64_microsoft-windows-a..modernappmanagement_31bf3856ad364e35_10.0.19045.3636_none_23b3b3ece690d77b\EnterpriseModernAppMgmtCSP.dll
(p) CBS MUM Missing (n) Microsoft-Windows-Client-Features-Package~31bf3856ad364e35~amd64~~10.0.19045.4291
(p) CSI Manifest Corrupt (n) wow64_microsoft-windows-audio-volumecontrol_31bf3856ad364e35_10.0.19045.3636_none_4514b27cf12f35d5

  2. Determine the update containing the missing files.

    From the log entries, identify the Update Build Revision (UBR) numbers within the file paths:

    • In the EnterpriseModernAppMgmtCSP.dll file, the UBR number is 10.0.19045.3636.
    • In the Microsoft-Windows-Client-Features-Package package, the UBR number is 10.0.19045.4291.

  3. Match the UBR number to the KB number:

    1. Go to the Windows update history page for your version (for example, Windows 10, version 22H2).
    2. Match the UBR number (3636 or 4291) to the listed updates to find the KB number.

    For example:

    • UBR 3636 might correspond to KB5031445.
    • UBR 4291 might correspond to KB5036892.

  4. Search for and download the update by the KB number:

    1. Use the identified KB numbers to search for the updates in the Microsoft Update Catalog.
    2. Download the updates associated with each KB number to restore the missing or corrupted files.

Step 3: Extract the .msu and .cab files

To address the corrupted files identified in the CBS.log file, extract the missing files into a specific folder. Follow these steps to extract the .msu and .cab files by using the provided PowerShell script, and then copy the necessary files to the C:\temp\Source folder.

  1. Create the necessary folders.

    Run the following command to create the C:\temp\Source folder if it doesn't exist:

    mkdir C:\temp\Source

  2. Use the instructions and script in Scripts: Extract .msu and .cab files to extract the .msu files by providing the destination paths of the .msu files.

Step 4: Repair the corrupted files by using the source files

  1. Copy the correct versions of the corrupted files.

    Copy the correct versions of all the corrupted files that belong to this update to the C:\temp\Source folder. For example, run the following command:

    Copy-Item "C:\path\extractedFiles\corruptedfile.dll" -Destination "C:\temp\Source"

    Repeat this process for each corrupted file identified in the log until all the corrupted files are copied to the C:\temp\Source folder.

  2. Rerun the DISM command.

    Open a command prompt as an administrator and run the following DISM command with the /Source option:

    DISM /Online /Cleanup-Image /RestoreHealth /Source:C:\temp\Source\ /LimitAccess

Step 5: Verify and confirm

  1. Rerun the DISM command.

    Rerun the following DISM command to verify that the issues have been resolved:

    DISM /Online /Cleanup-Image /ScanHealth

  2. Check the CBS.log file.

    Review the CBS.log file to ensure there are no remaining errors.
