Is is possible to query multiple WMI sources like you can multiple tables in SQL?
@"SELECT Win32_Process.ExecutablePath, Win32_Process.Handle, Win32_Process.Name, Win32_PerfFormattedData_PerfProc_Process.WorkingSetPrivate, Win32_PerfFormattedData_PerfProc_Process.PercentProcessorTime FROM Win32_Process, Win32_PerfFormattedData_PerfProc_Process
This didn't work but hopefully you get the idea. I've searched around and I couldn't even find anyone asking this question. I'm guessing it's not possible but I thought I'd try the experts here before giving up.
