My Xbox that I unenrolled out of insider is still on an Insider Build

You can be an Insider but not on any System builds. It would allow you to test games and apps they have, such as Sea of Thieves Insider builds or Minecraft insider builds while still being on the current system OS, if you want.

But to your question, to remove the system from the Insider Builds, this process walks you through how to remove the system.

If you have any questions about that, I'd be happy to help answer!

hey it looks like your on an insider build, can you unenroll from it??

It may be worth asking over this on the Xbox insider reddit https://www.reddit.com/r/xboxinsiders/ as they will probably be able to help you more

Thanks for the reply.

I have tried that and unfortunately it doesn't work. The xbox jo longer shows on the insider hub as it's been unenrolled. Still stuck in update loop. It's applying the update and stuck on 53%. The OS at the bottom of the screen is showing a dev build

As previously advised, the version, 18363.7196.191016-1200, is an Omega Insider build; refer to Insider Hub >Manage Devices; so therefore a OSU (Offline System Update) cannot be used unless the console is first unenrolled from the Insider preview program.

If you are signed up for the Insiders Program for the beta builds, you can unenroll from the program and prevent other issues coming up for you.
