Windows Live Alerts, formerly MSN Alerts, is a part of the Windows Live services from Microsoft that allows users to get notification of time-sensitive events and information from various alert content providers. Users are able to choose how and when to receive alerts, so that users may stay informed no matter where they are. Windows Live Alerts is a free service and can only be used with a Windows Live ID. However, some content providers or wireless service providers may charge for using their content or service with Windows Live Alerts.
