UPS has endpoints and support for Windows push (WNS). We don't support it and don't maintain it and it should be removed. This covers the following :

• WINDOWS_WNS Variant Type
• WindowsWNSVariant and WindowsVariant classes
• WNSPushNotificationSender and its Provider method
• WNSPushMessageQueue queues in jms and ejbs
• WNS Tests
• WindowsVariantEndpoint
• Windows sender properties (tile, etc)
