So you don't have a metered connection and have never disabled it.

You have reset Windows update like this:


You have run the Windows update troubleshooter.


Have you run Tweaking.com's free cautious repair tool?

- just repair 17?

And what is the state of your Windows update service?

(Windows key + R, services.msc)

If you can access the internet, it shouldn't be a driver problem - you say Windows update has never worked for you using Win 10 - which will use different drivers.

Are you certain your internet connection isn't metered? This is a difference between Win 7 and Win 10 as updates are not delivered over a metered connection (until you upgrade to the Creator's Build when 'critical' updates will be).
Sorry for not informing you before, I was working.I ran this tool and it already searches automatically, thank you very much for your help.
