How do I get the xbox update preview?

You have to be invited by someone already in the program. Even then you are not guaranteed to get selected.

Oh and do not ask for invites on here. The mods don't like it.

I am registered for the preview update how do you get the download for it?

Hello jsrockett. Please check this link:

Check the last part of the FAQ Titled : "I registered to preview the updates, but I don't have access to the private forum. How do I get access?" I Hope you have a twitter account. If none, then I suggest you create one.

I've not had an update from the preview program. i'm not on a second hand console. i don't have the preview program on my console. if it isn't on my console how do i get out of this program? How did i get into it in the first place? i went to the forum
to get help but it said no such group found. i checked my last updates and i've not gotten any updates from a preview program. i'm a little bothered i've been enrolled without me authorizing it.
