I came across these 2 new DMV’s in SQL server 2012 and found them available in R2 also. The DMV’s are very helpful and insightful. Below is a brief about the 3 new DMV’s.
1) SELECT * FROM sys.dm_server_registry:- Use this dynamic management view in SQL Server 2008 R2 SP1 and later versions to return information such as the SQL Server services that are available on the host machine or network configuration values for the instance of SQL Server.

2) SELECT * FROM sys.dm_server_services:-Use this dynamic management view to report status information about SQL Server, Full-Text, and SQL Server Agent services in the current instance of SQL Server.
