Fix Windows Update Errors
1] Try again
As mentioned earlier, many times, an update may fail to install in the first instance, but for some inexplicable reason, succeeds in the 2nd or 3rd try. So try a couple of times.
2] Delete Temporary Files and Browser Cache
If you are unable to install Windows Updates, first clear up your Temporary Files and Browser Cache, reboot, and try again. See if this helps resolve the issue. Best and easy to use the built-in Disk Cleanup utility or CCleaner.
3] Disable your Firewall and Anti-virus software
Temporarily Disable your Firewall and Anti-virus software and try again. Here is a list of Windows files and folders you may exclude from Antivirus scans.
4] Run SFC and DISM
Run System File Checker to replace potentially corrupted system files.
You can also fix corrupted Windows Update system files using DISM Tool. The Dism.exe tool can be used in different situations, and one of them is to repair a corrupted Windows Update files. Do note that you need to run a different command if you want to repair corrupted Windows Update System Files. If you run the usual /RestoreHealth command, it may not necessarily help.
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.
These can help fix problems that might prevent Windows Updates from installing.

Any failed updates will have error code/s written next to them. Note them down. If you find just too many entries too confusing delete this WindowsUpdate.log and try installing the problematic updates again.
Now open the newly re-created WindowsUpdate log file and have a look at its contents.
