What is game streaming?

Game streaming is the ability to play Xbox One games remotely from your Xbox One console on any Windows 10 PC on your home network.

This feature allows you to leave your living room and play your favorite Xbox One games anywhere with access to your home network.
Game streaming uses the power of the Xbox One console to manage the game. Your Windows 10 PC becomes a remote second screen so you can roam freely around your home while continuing to enjoy your Xbox One console and games.
System requirements

To take advantage of game streaming, you need:

Xbox One console: Game streaming must be enabled in Settings.
Windows 10 PC: You must be signed in to the Xbox app with the same gamertag as on the Xbox One console.
Network connectivity: The Windows 10 PC and the Xbox One console must be on the same home network. Options:
Wired - Ethernet connection (recommended for both PC and Xbox One console)
Wireless - 802.11 N/AC wireless connection
For best performance, we recommend that your Windows 10 PC have:

At least 2 gigabytes of RAM
1.5 GHz CPU or faster
Network connection to your home network:
Best performance: Wired Ethernet connection
Good performance: Wireless – 5 GHz 802.11 N or 802.11 AC wireless access point
Limited performance: Wireless – 2.4 GHz 802.11 N or 802.11 AC wireless access point
Note If a wired connection is not practical in your home due to the distance between your console and your home networking device, you can invest in either of two additional options that take advantage of the existing wiring in your home:

Powerline network adapters – These adapters allow you to use the existing electrical wiring of your home as a high-speed wired network.
MoCA (Multimedia over Coax) – These adapters allow you to use the existing coaxial cable wiring of your home as a high-speed wired network.
How to start game streaming from your Xbox One to your Windows 10 PC

Enable settings on your Xbox One

To use Xbox game streaming, you must first enable game streaming from your Xbox One. To do this, go to Settings and select Preferences. Make sure these two settings are enabled:

Allow game streaming to other devices (beta)
The Preferences screen is displayed. Under SYSTEM & APP, the 'Allow game streaming to other devices (beta)' checkbox is selected.
Enable the SmartGlass connection From any SmartGlass device or Only from profiles signed in on this Xbox.
The Preferences screen is displayed. Under 'SMARTGLASS CONNECTIONS' the choice 'From any SmartGlass device' is selected.
Connect your Windows 10 PC to your Xbox One
After ensuring that your console settings are correct, you need to establish a connection from your Windows 10 PC to your Xbox One console from within the Xbox app on your PC:

On your PC, launch the Xbox app.
Select Connect from the panel on the left side.
The Xbox app will scan your home network for available Xbox One consoles. Select the name of the console you want to connect to.
The 'Connect to your Xbox One' window has the 'MyXboxOne' selection surrounded by a red box. The entry indicates that it is connected.
Note All Xbox One consoles are pre-named "MyXboxOne." If you have multiple consoles, you should rename each one so that you can correctly identify the console you're trying to connect to. You can rename your console by going to Settings on your Xbox One and then selecting System. Console name is the first option on the System screen.

Once you have connected, you'll see the icons change to indicate you are connected, and you'll see new options for streaming, power, and media remotes. You'll also now have control of the console remotely.
The 'Connect to your Xbox One' window has the 'Connect automatically' checkbox selected for MyXboxOne. Underneath that is the 'Now Playing' display. It indicates what is now streaming from the Xbox One console.
How to launch game streaming from the Connection panel

To begin streaming, click Stream once the console is connected.

The 'Connect to your Xbox One' window has the 'MyXboxOne' selection. The 'Stream' option is highlighted with a red box.
How to launch a game from the Xbox app

Connect your console to your PC, as described previously. After you click on any Xbox One game in the Xbox app, you can initiate streaming from within that game hub. Just click Play from console in the upper-right corner of the screen.

On the 'Halo: The Master Chief Collection’ screen, the game's 'Activity feed' tab is shown. The 'Play from console' selection in the upper-right of the screen is circled.
The game will be immediately launched on the Xbox One console, and streaming will start.

How to change streaming quality

After your PC is connected to your Xbox One console, you can select a quality level for the video. You can change the quality of your stream before you start streaming or while you are streaming. You should set the quality to the highest level that still gives you a good gameplay experience.

In the Xbox app, click Settings, and then select Game streaming.
On the 'Settings' window, the 'Game streaming' tab is selected. On this tab, under Quality, the 'Video encoding level' selection is set to 'Medium.'
Under Video encoding level, select a streaming quality. We recommend:
High – If both your Xbox One and your Windows 10 PC are connected with a wired Ethernet connection, or if your console and the PC are in the same room as the wireless router with minimal wireless interference.
Medium – For 5 GHz wireless networked PCs and consoles that are in different rooms within your home.
Low – For low-end PCs and tablets, as well as 2.4 GHz wireless networks.
Note You can always start with a higher setting and reduce your quality level until you reach the best performance your home network will support based on your current configuration. To try to improve your game streaming experience, see Improve Xbox app for Windows 10 game streaming performance.
