Windows fails to install Cumulative update

Copper Contributor

Hello to everyone


I'm having issue updating a Windows 10 which specifically fails to update the last comulative updates. as additionl info Windows Patching is managed by SCCM not by WSUS.


  1. Initially i've tried to fix windows update client with troubleshooter, then stopping the Windows update service, renaming the C:\Windows\SoftwareDistribution folder and restarting the service with any effect.
  2. the i used the command sfc /scannow and dism.exe /Online /Cleanup-image /Restorehealth 

          they found corrupt file but they were unable to repair.


    3.   Then  i have create a Windows 10 Enterprise ISO with the Media Creation Tools  and once mounted i tried  to run dism.exe /Online /Cleanup-image /Restorehealth /source:J:\Sources:\install.esd:3 /limitaccess 


It fails again with the error "the source files could not be found" even if the install.esd was accessible and the index 3 specified Windows 10 Enterprise edition


what am I doing wrong?


Thanks in advance

Hi @Jorks,

you allready tried some troubleshooting steps, but you can try these also:

1. Check for sufficient disk space:

- Right-click on your system drive (usually C:) and select Properties.

- Check the Available space value.

- If the Available space value is less than 10 GB, you will need to free up some disk space before installing the update.

2. Check for pending updates or previous update installations that are stuck:

- Open a Command Prompt as an administrator.

- Type schtasks /Run /Tn "Microsoft\Windows\WindowsUpdate\Automatic App Update" and press Enter.

This will trigger the installation of pending updates.

- If any updates are stuck, you can try restarting the Windows Update service.
To do this:

- Open the Services console by typing services.msc into the Run dialog (Win + R).

- Scroll down to the Windows Update service and right-click it.

- Select Restart.

3. Use the Windows Update Catalog to manually download and install the update:

- Go to the Microsoft Update Catalog website (

- Search for the specific update you're trying to install by its KB number.

- Download the update that matches your system architecture (32-bit or 64-bit).

- Double-click the downloaded update file to install it.

4. Check for third-party software conflicts:

Temporarily disable or uninstall any security software, system optimization tools, or other third-party applications that might be causing conflicts.

5. Perform an in-place upgrade of Windows 10:

- Download the Windows 10 Media Creation Tool from the Microsoft website (

- Run the Media Creation Tool and select the Upgrade this PC now option.

- Follow the on-screen instructions to complete the upgrade process.
