There is problem out at the minute with Xbox insiders they are trying to sort it out now was to do with there newest update

When you check Whats new xbox one system updates you'll notice that the XBOX 1 General
Availability operating system is updated usually every month.

It's a lot more frequent if your in a Insider preview.

If you get updates that frequently, it's because you VOLUNTARILY signed up for the Insider Preview Program, which includes FORCED updates if the console hasn't been able to update during other times.

If the updates frequency is bothering you so much, you can move to a different (lower) ring of the Insider Preview program, where you get less frequent updates, or leave the Insider Preview Program completely, and you only get one update per month, that
will be installed while your console is in standby while in "Instant On Mode", or if you're still in the update window, when you shut down the console next.

If you are past the update window, the update will be forcibly installed when you start up the console.

If you're receiving updates that frequently, then it is very likely that your console is enrolled in an Xbox Insiders Build.

As you can see here, there were two system updates this month, but the one before that was August. I would recommend reviewing if your console is enrolled,

and unenroll it if you would not like as frequent system updates.

you are probably in the Insider program. That means you get the newest features and updates as one of the first. You can opt out of this programs. This will involve resetting the Xbox to default. Than you only will receive the normal updates.
