markets.books.microsoft

Using an alternative browser is only a partial solution.  I use Vivaldi which is different but far better in its design than edge and it is nominated as my default browser in Windows 10.  None the less despite this, if I navigate to a web site from any shortcut on either my Desktop, Start page or in another document including emails, Windows 10 automatically uses Edge and Bitdefender logs a notification that it has blocked "markets.books.microsoft". (where ever it originates).

In NO WAY, SHAPE, OR FORM have I EVER accessed a microsoft service ...

Um ... you're doing it now.

perhaps instead of just running on expired certificates, M$ could just renew and update the cert?

it would take 10 minutes of an engineers time to generate the new cert.

Why would MS renew a certificate for a website that no longer exists?

No, since it's the Microsoft Windows Store or Microsoft Edge attempting to communicate with the unsafe, unsupported Microsoft site, Microsoft should fix Microsoft's annoying, huge problem.  See the key there?  Microsoft.  Bitdefender is not in charge of Microsoft's apps or expired certs lol.

Just because edge is attempting to access the url doesn't mean that edge is initiating the command. It may be that a third party app is attempting to access the app and because edge is your default browser, then that's what it uses. It's bitdefenders job to recognise a dead link and suppress warnings from it. MS can't be expected to keep a cert updated to a dead site
