Python固然强大，但是调用WMI还是用VBS比较“正宗”。

复制代码 代码如下:
On Error Resume Next
strComputer = "."

Set objWMIService = GetObject("winmgmts:\\" & strComputer & " oot\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_Processor",,48)

For Each objItem in colItems
WScript.Echo "LoadPercentage: " & objItem.LoadPercentage
Next
