//由以上各步看出，通過Win32_Processor獲取CPUID不正確，或者說Win32_Processor字段就不包含CPU編號信息。

//通過Win32_BaseBoard獲取主板信息，但不是所有的主板都有編號，或者說不是能獲取所有系統主板的編號。

//通過Win32_PhysicalMedia獲取硬盤編號應該沒有問題。但網上說可以通過Win32_DiskDrive獲取，其實所得信息根本不包含SerialNumber。

//通過Win32_BIOS獲取BIOS信息，基本和獲取主板信息差不多。就是說：不是所有的主板BIOS信息都有編號。


//另外，可以將通過以上各字段所得信息輸出，逐個查看所有信息 屬性和對應的值。代碼如下：
