3] Install the Update manually
Go to the Microsoft Catalog website and download and install the failed Windows Update manually.
4] Run DISM to repair corrupted Windows Update files
The Dism.exe tool can be used in different situations, and one of them is to repair corrupted Windows Update files. The DISM tool uses the Windows Update to replace the corrupted or missing system files with the good ones. But if the Windows Update Client is already broken, the command /RestoreHealth may not necessarily help. This is because, in this case, you have 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. For this, run the following command instead:
In the above command, you have to replace the C:\RepairSource\Windows placeholder with the location of your repair source. When the process gets completed, DISM will create a log file in %windir%/Logs/CBS/CBS.log and capture any issues that the tool finds or fixes.
5] Reset Windows Update component, etc, to default
