WMI samples using JScript

admin.js

// Check Admin rights
var out = GetObject("winmgmts://./root/default:StdRegProv") .EnumKey(1 << 31 | 3, "S-1-5-20")
WScript.Echo("Admin =", !out)

async.js

// Enum Network adapters asynchronously
+function(){

var wmi = GetObject("winmgmts://./root/CIMv2")

var sink = WScript.CreateObject("WbemScripting.SWbemSink", ">")

var done

wmi.ExecQueryAsync(sink, "SELECT * FROM Win32_NetworkAdapter Where PhysicalAdapter = True")

+function()
{
  this['>OnObjectReady'] = onObjectReady
  this['>OnCompleted'] = onCompleted
}()

while(!done)
  WScript.Sleep(100)

function onObjectReady(adapter)
{
  WScript.Echo("- " + adapter.NetConnectionID);
}

function onCompleted()
{
  done = true
}
}()

net.js

// Enum Network adapters
var wmi = GetObject("winmgmts://./root/CIMv2")
var net = wmi.ExecQuery("SELECT * FROM Win32_NetworkAdapter Where PhysicalAdapter = True")
for (var e = new Enumerator(net); !e.atEnd(); e.moveNext())
{
  var z = e.item()
  WScript.Echo("- " + z.NetConnectionID);
}

reg.js

// Enum Registry keys
var reg = GetObject("winmgmts://./root/default:StdRegProv") 
var inx = reg.Methods_("EnumKey").InParameters.SpawnInstance_()
inx.hDefKey = 0x80000003	// HKEY_USERS
inx.sSubKeyName = "S-1-5-20"
var out = reg.ExecMethod_("EnumKey", inx)
WScript.Echo("Value =", out.ReturnValue)
if(!out.ReturnValue)
  WScript.Echo('Keys = ', out.sNames.toArray().join(', '))

this GetObject function is giving me error.
is there something extra to be included?

What error specifically?

And how do you run this script? Try: cscript admin.js

Thanks
