C++读取硬盘序列号：有时在将程序或者打包库提供给第三方时，为了防止传播泛滥，或者有一定的版权问题，需要绑定特定的计算机设备。此时就需要读取计算机的一些硬件资源（硬盘、CPU、BIOS等），来计算一个验证码，达到一机一码的目的。

软件查看硬盘序列号

借助DiskGenius查看硬盘序列号，选中硬盘，即可看到在下方有序列号。不过貌似SSD和机械硬盘的序列号格式是不一样的
SSD: 12位序列号
机械硬盘： 8位序列号

C++实现读取硬盘序列号

代码实现

代码实现使用的是微软提供的WMI Providers库， 读取不同硬件设备有不同的类，具体查看上面的MSDN链接。

我在实验过程中，获取CPU序列号失败，简单搜了一下，是VMI的问题使用ManagementClass(“Win32_Processor”)获取cpuid失败的解决办法[原创]，不过我没有测试，有兴趣的可以尝试一下。
