Hi, I'm Robinson, an Independent Advisor and a Windows user like you.
It might be that something went wrong with the update files itself. Clearing the folder where all of the
update files are stored will force Windows Update to download fresh files.
Here how to clear update database cache, reset windows update components to the default setup.
1-Press Windows + R, type services.msc and ok to open windows services.
2-Scroll down and look for windows update service.
3-Right-click on it and select stop.
4-Also, do the same with BITs (Background Intelligent Transfer Service) and Superfetch (superfetch now called sysmain) right-click and select stop.
5-Now Go to the following location C:\Windows\SoftwareDistribution\Download.
6-Delete everything inside the download folder, but do not delete the folder itself.
To do so, press CTRL + A to select everything and then press Delete to remove the files.
Again open windows services and restart the services (windows update, BITS) which you previously stopped.
Restart Windows, and check for updates from settings, update & security.
