本文介绍两种获取计算机CPU序列号的方法：一是通过API调用，二是利用WMI（Windows Management Instrumentation）脚本。这两种方法均适用于Windows操作系统，并详细展示了使用VBA（Visual Basic for Applications）实现的具体代码。

第一种：API：

  Private   Type   OSVERSIONINFO
                  dwOSVersionInfoSize   As   Long
                  dwMajorVersion   As   Long
                  dwMinorVersion   As   Long
                  dwBuildNumber   As   Long
                  dwPlatformId   As   Long
                  szCSDVersion   As   String   *   128             '     Maintenance   string   for   PSS   usage
  End   Type
  Private   Declare   Function   GetVersionEx   Lib   "kernel32"   Alias   "GetVersionExA"   (lpVersionInformation   As   OSVERSIONINFO)   As   Long
  Private   Declare   Function   GetComputerName   Lib   "kernel32"   Alias   "GetComputerNameA"   (ByVal   lpBuffer   As   String,   nSize   As   Long)   As   Long

  Public   Function   GetCPUid()   As   String

          On   Error   GoTo   doError

          Dim   len5   As   Long,   aa   As   Long
          Dim   cmprName   As   String
          Dim   Computer   As   String
          Dim   CPUs   As   Object,   MyCpu   As   Object
          Dim   osver   As   OSVERSIONINFO
          Dim   SerialNo   As   String

          '取得Computer   Name
          cmprName   =   String(255,   0)
          len5   =   256
          aa   =   GetComputerName(cmprName,   len5)
          cmprName   =   Left(cmprName,   InStr(1,   cmprName,   Chr(0))   -   1)
          Computer   =   cmprName                 '取得CPU端口号
          Set   CPUs   =   GetObject("winmgmts:{impersonationLevel=impersonate}!\\"   &   Computer   &   "\root\cimv2").ExecQuery("select   *   from   Win32_Processor")
          For   Each   MyCpu   In   CPUs
                  SerialNo   =   MyCpu.ProcessorId
                  Exit   For
          Next
          GetCPUid   =   SerialNo
          Exit   Function
  doError:
          GetCPUid   =   ""
    End   Function
第二种：使用类：

'Microsoft   WMI   Scripting   V1.1   Library的引入
    Public Function GetProcessorID() As String
      Dim a     As SWbemServices
      Dim b     As SWbemObjectSet
      Dim c     As SWbemObject
      Dim d     As SWbemPropertySet
      Dim e     As SWbemProperty
      Dim str As String


      Set a = GetObject("winmgmts:")
      Set b = a.InstancesOf("Win32_Processor")
      For Each c In b
            With c
                If .Properties_.Count > 0 Then
                    Set d = .Properties_

                    For Each e In d
                      If UCase(e.Name) = UCase("ProcessorId") Then
                          str = e.Value
                      End If

                    Next
                End If
            End With
      Next
      GetProcessorID = str

End Function
