Manage preview builds

Enable this policy to manage which updates you receive prior to the update being released to the world.

Dev Channel
Ideal for highly technical users. Insiders in the Dev Channel will receive builds from our active development branch that is earliest in a development cycle. These builds are not matched to a specific Windows 10 release.

Beta Channel
Ideal for feature explorers who want to see upcoming Windows 10 features. Your feedback will be especially important here as it will help our engineers ensure key issues are fixed before a major release.

Release Preview Channel (default)
Insiders in the Release Preview Channel will have access to the upcoming release of Windows 10 prior to it being released to the world. These builds are supported by Microsoft. The Release Preview Channel is where we recommend companies preview and validate upcoming Windows 10 releases before broad deployment within their organization.

Note: Preview Build enrollment requires a telemetry level setting of 2 or higher and your domain registered on insider.windows.com. For additional information on Preview Builds, see: https://aka.ms/wipforbiz

If you disable or do not configure this policy, Windows Update will not offer you any pre-release updates and you will receive such content once released to the world. Disabling this policy will cause any devices currently on a pre-release build to opt out and stay on the latest Feature Update once released.
