When using WMI, the naming structure for counter information is different from using Get-Counter. With WMI, counters are exposed via separate WMI classes whose names are slightly different from those you use with Get-Counter. Effectively, with WMI, each performance counter set is a WMI class.

The Win32_PerfFormattedData_PerfOS_Memory WMI class contains 46 properties, including the numerous individual performance counters.
