I have windows 11 how do I use the built in VPN?

Actually, I was recently surprised to see that Microsoft has just begun to offer a VPN service operating from within the Edge browser on my Windows 10 in S Mode device, which I noticed because it was displayed as an option in the 'Browser Essentials' pull-down menu that had a little green dot to grab my attention.

Apparently, it's a smart VPN integrated into Edge that only operates when needed for situations like unsecured Wi-Fi in airports or other free public networks, so the 5GB/month offered free will likely be enough for most light-duty users who only occasionally operate in these environments.

However, note that this is NOT the same sort of VPN that some more paranoid people use to try and remain anonymous while online, in order to avoid being tracked for advertising or other purposes. It's really just a way to protect you from the potential that your free Wi-Fi connection might be monitored and either your credentials stolen, or activity tracked for any websites that also don't happen to include their own SSL (https) secured transport, which is uncommon for most sites like banks many major retail or other important services today.
