This tutorial explains how to update the software of the Xbox One console. Updates bring new features aiming to improve your experience, improve existing ones, fix known errors and are sometimes necessary to run the latest games.
The Xbox One can automatically check for new updates and download them when the Instant-On mode is enabled.
The first step is to make sure that your console is connected to the internet - Go to Settings > Network > Set up wireless network.
You can now enable the Instant-On mode - Go to Settings > Power & Startup > Power mode. Select the Instant-on mode and tick the Automatically download updates checkbox.
To check and install new updates manually: Press on the Menu button of your controller and then go to Settings > System. Select Update console and if an update is indeed available the It's time to update screen will appear. Press A to select the Start update option and follow the onscreen procedure.
