Manage the Chrome variations framework

Applies to managed Chrome browsers and ChromeOS devices.

As a Chrome administrator, you can use the ChromeVariations policy to manage the Chrome variations framework on Microsoft Windows, Apple Mac, and Linux and the DeviceChromeVariations policy to manage them on Chrome OS.

Important: We do not recommend disabling the Chrome variations framework. By doing this you can potentially prevent Google from quickly providing critical security fixes and significantly increases the risk of security and compatibility issues in your organization

Benefits

Using variations, Chrome can:

• Give a small group of users previews of new features and gather feedback.
• Slowly roll out changes to progressively larger groups of users and minimize the risk of incompatibilities.
• Provide faster security and other critical updates.
• Rollback features if a problem is discovered, without waiting for a new version of Chrome. The user only needs to restart their computer to get the new configuration.

Step 1: Review policies

Policy	Description
Chrome​Variations	Specifies which variations are enabled in Chrome for Windows, Mac, and Linux. Unset: Defaults to Enable Chrome variations, as described below.
DeviceChromeVariations	Specifies which variations are enabled in Chrome for Chrome OS. Unset: Defaults to Enabled, as described below.

What the policies manage

Setting these policies enables or disables the Chrome variations framework for deploying changes within your organizational units. You can also choose to enable them for critical fixes only.
