The "history" of security certificates on Windows Insider Program

Hello everyone,

A number of security certificates expire on September 30 at 4 p.m., and failure to replace them before the deadline could prevent affected machines from connecting to the Internet.

The expert who warned about this waited a week before the deadline to come forward, which meant that by the time the information circuits reacted, I was informed by an email yesterday at 6:02 p.m., and I read it a bit by chance.

What to check on a Vista machine?

As for telephones, I imagine that we only have a problem connecting to the Internet, that we can always make calls?

I guess I'll have to try asking the question in different places, because here if we answer in a day or two that's okay.
