I'm aware that Windows update is NO MORE. I've given you a web site that gives you a shell script that takes care of that. What you need most is those TRCs.

OK! There you go. A simple Google search:
https://www.google.com/search?client=fir...+Windows+7

.. yielded this:
https://support.microsoft.com/en-us/help...tificate-p

and this:
https://support.microsoft.com/en-us/help...for-window

You're in luck!

Thanks @fChk for your help. All of the websites are now working well. Chrome and Edge both are showing them secure.I have successfully installed these updates and everything is fine. On the other hand about system information. I have more information about hardware than software. We will discus more about these thing in a separate topic.
Thanks all of those who helped me. A special thanks to Hidden Refuge for such explanation about the issue.
