Update policy override

Specifies how Google Update handles available Google Chrome Canary Build updates from Google. If this policy is not configured, Google Update handles available updates as specified by "Update policy override default". Options: - Always allow updates: Updates are always applied when found, either by periodic update check or by a manual update check. - Manual updates only: Updates are only applied when the user does a manual update check. (Not all apps provide an interface for this.) - Automatic silent updates only: Updates are only applied when they are found via the periodic update check. - Updates disabled: Never apply updates. If you select manual updates, you should periodically check for updates using the application's manual update mechanism if available. If you disable updates, you should periodically check for updates and distribute them to users. Check https://www.google.com/chrome/browser/canary.html. This policy is available only on Windows instances that are joined to a Microsoft® Active Directory® domain.
