Symptom

Windows updates and service packs may fail to install if there are corruption errors. For example, an update might not install if a system file is damaged. The DISM or System Update Readiness tool may help you to fix some Windows corruption errors.

This article is intended for Support agents and IT professionals. If you are home users and looking for more information about fixing Windows update errors, see Fix Windows Update errors.

Resolution for Windows 8.1, Windows 10 and Windows Server 2012 R2

To resolve this problem, use the inbox Deployment Image Servicing and Management (DISM) tool. Then, install the Windows update or service pack again.

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

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

When you run this command, DISM uses Windows Update to provide the files that are required to fix corruptions. However, if your Windows Update client is already broken, use a running Windows installation as the repair source, or use a Windows side-by-side folder from a network share or from a removable media, such as the Windows DVD, as the source of the files. To do this, run the following command instead:

Replace the C:\RepairSource\Windows placeholder with the location of your repair source. For more information about using the DISM tool to repair Windows, reference Repair a Windows Image.

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

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.

Resolution for Windows 7 Service Pack 1 (SP1) and Windows Server 2008 R2 SP1

To resolve this problem, use the System Update Readiness tool. Then, install the Windows update or service pack again.

What does the System Update Readiness tool do

Verify the integrity of resources

The System Update Readiness tool verifies the integrity of the following resources:

  • Files that are located in the following directories:
    • %SYSTEMROOT%\Servicing\Packages
    • %SYSTEMROOT%\WinSxS\Manifests
  • Registry data that is 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 System Update Readiness tool detects incorrect manifests, Cabinets, or registry data, it may replace the incorrect data with a corrected version.

Logging

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

How to fix errors that are found in the CheckSUR log file

To manually fix corruption errors that the System Update Readiness tool detects but can’t fix, follow these steps:

%SYSTEMROOT% is an environment variable that saves the folder in which Windows is installed. For example, generally the %SYSTEMROOT% folder is C:\Windows.

Identify the packages that the tool can’t fix. For example, you may find the following in the log file:

In this case, the package that is corrupted is KB958690.

Copy the package (.msu) to the %SYSTEMROOT%\CheckSUR\packages directory. By default, this directory doesn’t exist and you need to create the directory.
