How to disable Xbox system service on Windows 10 with Intune – Mobile-First Cloud-First

For every Windows 10 build Microsoft has released we are getting more and more MDM settings available in the operation system next version is no exception. In this blog post I will show how to disable the Xbox services with Intune. The new CSP – SystemService will first apply to the next major version of Windows 10 after 1709.

The System Service CSP allows us to configure the startup mode for the following services on Windows:

  • Home Group Listener Service
  • Home Group Provider Service
  • Xbox Accessory Management Service
  • Xbox Live Auth Manager Service
  • Xbox Live Game Save Service
  • Xbox Live Networking Service

It only applies to this version of Windows 10:

Create the profile in Intune:

  1. Name: Windows 10 – Custom – System Services Xbox
  2. Platform: Windows 10 and later
  3. Profile type: Custom
  4. Settings: Select Configure
  5. OMA-URI Settings: Click Add

In the OMA-URI Settings we create the settings

Xbox Live Auth Manager Service:

  1. Name: Xbox Live Auth Manager Service Startup Mode
  2. Description: Disable Xbox Live Auth Manager Service Startup
  3. OMA-URI: ./Device/Vendor/MSFT/Policy/Config/SystemServices/ConfigureXboxLiveAuthManagerServiceStartupMode
  4. Data type: Integer
  5. Value: 4

The value can be set to: Automaic(2), Manual(3), Disabled(4). Default: Manual

We need to do the same for the rest of the Xbox services.

Xbox Live Game Save Service:

  • Name: Xbox Live Game Save Service Startup Mode
  • Description: Disable Xbox Live Game Save Service Startup
  • OMA-URI: ./Device/Vendor/MSFT/Policy/Config/SystemServices/ConfigureXboxLiveGameSaveServiceStartupMode
  • Data type: Integer
  • Value: 4

Xbox Live Networking Service:

  • Name: Xbox Live Networking Service Startup Mode
  • Description: Disable Xbox Live Networking Service Startup
  • OMA-URI: ./Device/Vendor/MSFT/Policy/Config/SystemServices/ConfigureXboxLiveNetworkingServiceStartupMode
  • Data type: Integer
  • Value: 4

Xbox Accessory Management Service:

  • Name: Xbox Accessory Management Service Startup Mode
  • Description: Disable Xbox Accessory Management Service Startup
  • OMA-URI: ./Device/Vendor/MSFT/Policy/Config/SystemServices/ConfigureXboxAccessoryManagementServiceStartupMode
  • Data type: Integer
  • Value: 4

How does this looks like from the client side:

I have only tested this setting with Windows Insider build 17063.1000

Before the new created profile applies to the devices we can see the Xbox services is set to Manual startup

In the Windows 10 MDM Advanced Diagnostic Report we can see the default value before the new created profile applies to the devices

After the profile are successfully assigned to the device we can see the Xbox services is set to Disabled

In the Windows 10 MDM Advanced Diagnostic Report we can see the settings from the profile applies to the devices

At this moment the value set on the devices is now showed correctly in the Advanced Diagnostic Report

When the Xbox service is disabled the end user cannot sign in to the Xbox service

The profile can also be created with Powershell:
