如何获取Windows进程的CPU使用率？

我看了一下WMI Win32_Process的Class，如下：
class Win32_Process : CIM_Process
{
  string Caption;
  string CommandLine;
  string CreationClassName;
  datetime CreationDate;
  string CSCreationClassName;
  string CSName;
  string Description;
  string ExecutablePath;
  uint16 ExecutionState;
  string Handle;
  uint32 HandleCount;
  datetime InstallDate;
  uint64 KernelModeTime;
  uint32 MaximumWorkingSetSize;
  uint32 MinimumWorkingSetSize;
  string Name;
  string OSCreationClassName;
  string OSName;
  uint64 OtherOperationCount;
  uint64 OtherTransferCount;
  uint32 PageFaults;
  uint32 PageFileUsage;
  uint32 ParentProcessId;
  uint32 PeakPageFileUsage;
  uint64 PeakVirtualSize;
  uint32 PeakWorkingSetSize;
  uint32 Priority;
  uint64 PrivatePageCount;
  uint32 ProcessId;
  uint32 QuotaNonPagedPoolUsage;
  uint32 QuotaPagedPoolUsage;
  uint32 QuotaPeakNonPagedPoolUsage;
  uint32 QuotaPeakPagedPoolUsage;
  uint64 ReadOperationCount;
  uint64 ReadTransferCount;
  uint32 SessionId;
  string Status;
  datetime TerminationDate;
  uint32 ThreadCount;
  uint64 UserModeTime;
  uint64 VirtualSize;
  string WindowsVersion;
  uint64 WorkingSetSize;
  uint64 WriteOperationCount;
  uint64 WriteTransferCount;
};
似乎没有直接获取进程CPU使用率的项，请问还有什么方法可以做到？
谢谢！

Method: <OBJECT>.LoadPercentage:
Sample Code:

[Copy to clipboard] [ - ]

CODE:

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_Processor")
For Each objItem in colItems
Wscript.Echo "Load Percentage: " & objItem.LoadPercentage & " %"
Next

你这是CPU整体的使用率吧？
我要的是指定进程所占的CPU
