[Solved] Windows 10 Update Problem: Missing Important Security & Quality Fixes + Defender Issue

Hello to all forum users. I come with a problem that I can't update my windows. I go into Windows update and I get this message "Your device is missing important security and quality fixes." When I press the button to search for the missing update, it takes forever. Windows Defender is still missing with this problem, but I have no idea how. It just seemed to evaporate. I would like to ask for help

Restore the system to its initial settings.

delete the contents of the windows->software distribution directory
reset your computer and try again

I deleted it and after trying again it was "There were problems installing updates, but we will try again later. If this problem persists and you want to search the Internet or get information from technical support, use the error code: (0x80080005)"

I don't want to lose files and applications because there are a lot of them

If you have the opportunity, the factory settings sum sumarum will be the fastest

Which version of Windows 10 is it? - If not the latest one, you can always create an installation media with it and update it by running the installer file from the running system (selecting "keep files and settings" during the installation process).
Anyway, the same can be done with the version equal to the installed one (this is a replacement for the DISM.exe /Online /Cleanup-image /Restorehealth command).

Of course, this is only a workaround, but with a negligible degree of danger.

I recommend trying the tool in my attachment.

Download the tool to create installation media with the latest build for your system.
https://www.microsoft.com/pl-pl/software-download/windows10

EDIT:
Check the "image" of the current system first.

And later FIX from the attachment.
