Information

This policy setting determines whether users can access the Insider build controls in the Advanced Options for Windows Update. These controls are located under 'Get Insider builds,' and enable users to make their devices available for downloading and installing Windows preview software.

The recommended state for this setting is: Disabled.

Note: This policy setting applies only to devices running Windows 10 Pro or Windows 10 Enterprise, up until Release 1703. For Release 1709 or newer, Microsoft encourages using the Manage preview builds setting (Rule 18.9.102.1.1). We have kept this setting in the benchmark to ensure that any older builds of Windows 10 in the environment are still enforced.

Rationale:

It can be risky for experimental features to be allowed in an enterprise managed environment because this can introduce bugs and security holes into systems, making it easier for an attacker to gain access. It is generally preferred to only use production-ready builds.

Impact:

The item 'Get Insider builds' will be unavailable.

Solution

To establish the recommended configuration, set the following Device Configuration Policy to Disabled:

To access the Device Configuration Policy from the Intune Home page:

Click Devices

Click Configuration profiles

Click Create profile

Select the platform (Windows 10 and later)

Select the profile (Custom)

Click Create

Enter a Name

Click Next

Configure the following Setting

Name: <Enter name>
Description: <Enter Description>
OMA-URI: ./Device/Vendor/MSFT/Policy/Config/System/AllowBuildPreview
Data type: Integer
Value: 0

Select OK

Continue through the Wizard to complete the creation of the profile (profile assignments, applicability etc.)

Note: More than one configuration setting from each of the Configuration profiles (ex: Administrative Templates, Custom etc.) can be added to each Device Configuration Policy.

Default Value:

Enabled. (Users can download and install Windows preview software on their devices.)
