Use the DISM tool

An Internet connection is required to use the tool as DISM uses Windows Update to provide the files necessary to fix the corruption.

Enter in the search field or in the start menu Powershell .
Right click on Powershell and select Execute as administrator.

The Powershell opens
Now give the command in the command prompt dism.exe / Online / Cleanup-image / Restorehealth  .
Note the spaces in front of the slashes.
Confirm the entry with Enter.



It will take a few minutes so be patient.

The DISM tool creates a log file in the path  % windir% / Logs / CBS / CBS.log
% windir% corresponds to your real Windows directory. So in many cases C: \ Windows.




Restart your computer and try to install the Windows update again.
