Windows 10 updates always fail

It's been at least one year since my Windows 10 computer always goes on error while manually trying to download new Windows Updates:

enter image description here

Trying again ("Riprova") doesn't work. I searched the web but I cannot find a real cause for the error 0x80d05011. I also tried to manually download some updates from https://www.catalog.update.microsoft.com/, but with no luck.

Any suggestion?

A year is too long to try small recent ideas.

At this point, you need to do a Windows 10 Repair Install.

Windows 10 is running, so click on the Download button (not Upgrade Button) and select Run.

Use the option to Keep Everything to begin with. That will usually (but not always) work.

See if Keep Everything works for you.

The remaining two options (Keep only Data and then Keep Nothing) are much more aggressive.
