какая операционка?

Requirements Client Requires Windows Vista. Server Requires Windows Server 2008. Type Library Use Wbemdisp.tlb. DLL Requires Wbemdisp.dll.

может поэтому?

а вот так сработает (js):

Код:

var strComputer = ".";
var objWMIService = GetObject("winmgmts:\\\\" + strComputer + "\\root\\cimv2");
var iter = new Enumerator(objWMIService.ExecQuery("Select * from Win32_Process"))

for (; !iter.atEnd(); iter.moveNext())
{
    WScript.Echo(iter.item().Caption);
}

или так: (vb)

Код:

strComputer = ".";
set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2");

for each item in objWMIService.ExecQuery("Select * from Win32_Process")
    WScript.Echo item.Caption
next
