Like the error says, that object doesn't have a popup method. – js2010

PopUp is a method called from the Wscript.Shell class. It won't work from a WMI instance object (or collection of instances). If you wanted to display the results of that WMI query using the pop-up style message box from your example you would have to do something like this.

$out = Get-WmiObject -class Win32_PerfFormattedData_Tcpip_NetworkInterface | select name , BytesTotalPersec | Out-String

$wshell = New-Object -ComObject Wscript.Shell
$wshell.Popup("Network Status:`n $out",0,"Done",0x1)

Or you can simplify it a bit by just piping the data to a gridview.

Get-WmiObject -class Win32_PerfFormattedData_Tcpip_NetworkInterface | select name , BytesTotalPersec | Out-GridView

Hope that helps.
