I assume a public operating system build - how would i know?

If you have owned the console since new and never enrolled in the Xbox Insider preview (downloaded the Xbox Insider Hub and joined) then you will be on a public build. If it is a pre owned console, then download the Insider Hub app from the Xbox store and
open it. On the left hand side of the landing screen you will see settings, open that and go to manage devices. It will show there if it is enrolled and you can remove it if it is. They do recommend not using an extension (though most I would suspect, here
in the UK do)

To become an insider, download the Xbox Insider Hub app on your console. You join through the app. After that, you can join various betas.
