我正在寻找总的提交费用。

解决方案

这是使用WMI的示例：

strComputer = "."

Set objSWbemServices = GetObject("winmgmts:\" & strComputer)
Set colSWbemObjectSet = _
 objSWbemServices.InstancesOf("Win32_LogicalMemoryConfiguration")

For Each objSWbemObject In colSWbemObjectSet
 Wscript.Echo "Total Physical Memory (kb): " & _
 objSWbemObject.TotalPhysicalMemory
 WScript.Echo "Total Virtual Memory (kb): " & _
 objSWbemObject.TotalVirtualMemory
 WScript.Echo "Total Page File Space (kb): " & _
 objSWbemObject.TotalPageFileSpace
Next

如果在CScript下运行此脚本，则应该在命令窗口中看到目标计算机上安装的物理内存的千字节数。以下是脚本的典型输出：
总物理内存(kb)：261676

编辑：包括的总页面文件大小属性
