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 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.

1. Open an elevated command prompt. To do this, swipe in from the right edge of the screen, and then tap Search. Or, if you are using a mouse, point to the lower-right corner of the screen, and then select Search. Type Command Prompt in the Search box, 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.

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

   Important

   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:

   Note

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

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.

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.

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:

.log File Extension

1. Open %SYSTEMROOT%LogsCBSCheckSUR.log.

   Note

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

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

   Summary:

   Seconds executed: 264
   Found 3 errors
   CBS MUM Missing Total Count: 3
   Unavailable repair files:

   servicingpackagesPackage_for_KB958690_sc_0~31bf3856ad364e35~amd64~~6.0.1.6.mum
   ...

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

3. Download the package from Microsoft Download Center or Microsoft Update Catalog.

4. Copy the package (.msu) to the %SYSTEMROOT%CheckSURpackages directory. By default, this directory doesn't exist and you need to create the directory.
