Missing WMI class in Windows Vista and Windows Server 2008   

In neither Vista nor W2008 we found 
win32_perfrawdata_termservice_terminalservices class. Is there any way to 
obtain that class on those OS? Is the class deprecated? There are other 
classes we can use to retrieve the data that that class offered? Will have 
that class the final version of Windows Server 2008?

Regards,
Tango
