os.name system property value in Java for Windows Server 2008

Does anyone know the value of the Java system property "os.name" on Windows Server 2008? I found a rally going here (Crowdsourcing a Complete list of Common Java System Prope开发者_运维技巧rties and Known Values), but nothing on Windows Server 2008. Any help is appreciated.

I believe it is "Windows Server 2008" and "Windows Server 2008 R2"
