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。
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

我要评论c++实现读取硬盘序列号参考资料(https://msdn.microsoft.com/en-us/library/aa389273(v=vs.85)
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。
- 硬盘 [win32_physicalmemory class](https://msdn.microsoft.com/en-us/library/aa394346(v=vs.85)
- cpu [win32_processor class](https://msdn.microsoft.com/en-us/library/aa394373(v=vs.85)
- bios [win32_bios class](https://msdn.microsoft.com/en-us/library/aa394077(v=vs.85)

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。
