How to access "Register MS-CFS3" through XBox?

It won't let me register my xbox one and I keep getting access denied. How do I register my system?

Hi, the best way is to register to their website, they have an Xbox Live login to make it easier.

Once you have registered you will be able to access the achievement trackers and also be able to use it on your xbox console through the app.

I hope this helps.

If it's not under warranty, I believe the rate through MS is $100 (a rip off), but don't quote me on that. If it's under warranty, it won't cost you anything. When you purchased your 360, it was scanned at the register, so MS knows when that console was
bought. If you registered your console, things will be easier.

As a new user, I'd really like to understand how Netflix, Vudu, etc... access goes down. These are apps that shouldn't rely on Xbox live or any MS components after being downloaded. I agree, it would be nice to have a place to register a complaint instead
of being so public. Since they don't have one, I guess we all get to air everything for the world to see how frustrating it is.

The same issue still persists.

The game DID ask (and get) Xbox Live Profile account access on first start. Visible on the MS account page. So it HAS the elevated privileges to read/write save files to the MS/Xbox user cloud data.

The game also is registered in the MS Win 10 Firewall settings. It has the privileges to pass data through the firewall.

Seems, after each time a user starts the game again, the (background?) Xbox profile login/hook and cloud save access does not happen.

Running the game with main Win 10 user profile (with Admin rights), with vanilla slow-tier Win 10 Pro Preview Build. No 3rd party AV. All other XBOX Pass PC games work/save as intended.
