Update policy override default

Lets you specify the default behavior for all channels concerning the way Microsoft Edge Update handles available updates for Microsoft Edge. Can be overridden for individual channels by specifying the 'Update policy override' policy for those specific channels. If you enable this policy, Microsoft Edge Update handles Microsoft Edge updates according to how you configure the following options: - Updates disabled (0): Updates are never applied. - Always allow updates (1) (recommended): Updates are always applied when found, either by periodic update check or by a manual update check. - Manual updates only (2): Updates are applied only when the user runs a manual update check. - Automatic silent updates only (3): Updates are applied only when they're found by the periodic update check. If you select manual updates, make sure you periodically check for updates by using the app's manual update mechanism, if available. If you disable updates, periodically check for updates, and distribute them to users. If you don't enable and configure this policy, Microsoft Edge Update handles available updates as specified by the 'Update policy override' policy. This policy is available only on Windows instances that are joined to a Microsoft® Active Directory® domain.
