I have the following error in my Google Chrome browser when accessing certain sites: Your connection is not private returned the following error code NET::ERR_CERT_AUTHORITY_INVALID

this is the error image

I just installed Windows 7 Home Premium version on my notebook and I came across this error, due to not having installed the updates, my configuration is basic and I would not want to go out installing a lot of updates until I find a specific one that solves the problem (I know which is because of updates because on another machine I installed the system, presented the due errors of unauthorized certificates, installed all the recommended updates and solved the problem)

I've tried to find the specific update on the Microsoft Update Catalog website but to no avail


When trying to perform updates through Windows Update, I return this: Windows was unable to check for new updates

Error(s) found:

Code 80072EFE Unknown error on Windows Update

  • Is W7 full updated using Windows Updates?

  • By default comes the tool that does this, Windows Update, but it has the Microsoft online catalog, where I can search for the update reference and install it manually Mar 10, 2021 at 21:16
  • so I don't know what the update reference is for this certificate error Mar 10, 2021 at 21:18
  • Why not run windows update?

  • my machine's settings are very weak, I install the system and stay calm, but after installing the updates it ends up slowing down the machine, when starting up, when opening installed programs, when executing processes, and it uses 100% CPU usage, this only after installing the updates recommended by Windows Update (we agree that it recommends unnecessary updates, but because it does not know the update specifies that it solves the problem it ends up showing these symptoms) Mar 10, 2021 at 21:22
