+<!--Description-->
+This policy allows Enterprise Admins to turn off the notification for company devices that the Edge Legacy browser is no longer supported after 3/9/2021 to avoid confusion for their enterprise users and reduce help desk calls. 
+By default, a notification will be presented to the user informing them of this upon application startup.
+With this policy, you can either allow (default) or suppress this notification.
+
+> [!NOTE]
+> This policy is only enforced in Windows 10 for desktop and not supported in Windows 10 Mobile.
