Python固然强大，但是调用WMI还是用VBS比较“正宗”。
On Error Resume Next
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_Processor",,48)
For Each objItem in colItems
WScript.Echo "LoadPercentage: " & objItem.LoadPercentage
Next
