DISM.exe /Online /Cleanup-image /Restorehealth
When you run the command mentioned above, DISM will replace potentially corrupted or missing system files with good ones.
However, if your Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or use a Windows side-by-side folder from a network share, as the source of the files.
You will then be required to run the following command instead:
DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess
Here you have to replace the C:\RepairSource\Windows placeholder with the location of your repair source.
Once the process is complete, DISM will create a log file in %windir%/Logs/CBS/CBS.log and capture any issues that the tool finds or fixes.
Close the command prompt, and then run Windows Update again and see it has helped.
