For example, an update might not install if a system file is damaged. The DISM or System Update Readiness tool may help you fix some Windows corruption errors.
Check this page for Windows Update troubleshooting scenarios.
Solution 1: Use DISM
The solution mentioned in this section applies to Modern Windows versions like Windows 11, Windows 10, Windows Server 2016, or later. For Windows 7 and Windows Server 2008 R2, check Solution 2: Use the System Update Readiness tool.
To resolve this problem, use the DISM tool. Then, install the Windows update or service pack again.
Open an elevated command prompt. To do this, open the Start menu or Start screen, 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 Allow.
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
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:
DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess
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.
sfc /scannowcommand 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.
Solution 2: Use the System Update Readiness tool
The solution mentioned in this section is applicable for Windows 7 and Windows Server 2008 R2. For Modern Windows versions like Windows 11, Windows 10, Windows Server 2016, or later, check Solution 1: Use DISM.
To resolve this problem, use the System Update Readiness tool. Then, install the Windows update or service pack again.
Download the System Update Readiness tool.
Go to Microsoft Update Catalog and download the tool that corresponds to the version of Windows that's running on your computer. For more information about how to find the version of Windows that you installed, see Find out if your computer is running the 32-bit or 64-bit version of Windows.
This tool is updated regularly, and we recommend that you always download the latest version. This tool isn't available in every supported language.
Install and run the tool.
Select Download on the Download Center webpage, and then do one of the following:
- To install the tool immediately, select Open or Run, and then follow the instructions on your screen.
- To install the tool later, select Save, and then download the installation file to your computer. When you're ready to install the tool, double-click the file.
In the Windows Update Standalone Installer dialog box, select Yes.
When the tool is installed, it automatically runs. Although it typically takes less than 15 minutes to run, it might take much longer on some computers. Even if the progress bar seems to have stopped, the scan is still running, so don't select Cancel.
When you see Installation complete, select Close.
Reinstall the update or service pack you were trying to install previously.
To manually fix corruption errors that the tool detects but can't fix, see How to fix errors that are found in the CheckSUR log file.
Solution 3: Use Microsoft Update Catalog
You can also try to download the update package directly from Microsoft Update Catalog, and then install the update package manually.
For example, you may have problems when you try to install updates from Windows Update. In this situation, you can download the update package and try to install the update manually. To do this, follow these steps:
Find the update that applies to your operating system appropriately in the search results, and then select the Download button.
Select the link of the file to download the update.
Select Close after the download process is done. Then, you can find a folder that contains the update package in the location that you specified.
Open the folder, and then double-click the update package to install the update.
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:
- Registry data that's located under the following registry subkeys:
- 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.
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:
Fix errors 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 information in the log file:
Summary: Seconds executed: 264 Found 3 errors CBS MUM Missing Total Count: 3 Unavailable repair files: servicing\packages\Package_for_KB958690_sc_0~31bf3856ad364e35~amd64~~184.108.40.206.mum ...
In this case, the package that's corrupted is KB958690.
Download the package from Microsoft Download Center or Microsoft Update Catalog.
Copy the package (.msu) to the
%SYSTEMROOT%\CheckSUR\packagesdirectory. By default, this directory doesn't exist, and you need to create it.
Rerun the System Update Readiness tool.
