【学习记录】VS2017+win7驱动开发，sys加载失败问题

突然想试试win7驱动程序的开发，然后毫不犹豫的写了个HelloWorld程序，不清楚笔记本还是开发环境出现了什么毛病（可能只有我自己的开发环境出现了问题，搜索网上未找到有相同的问题），一个Hello World程序总是提示加载失败

开发环境：VS2017+WDK 10.0.17763.1（SDK也是相同的版本）

驱动加载环境：原装Win7 sp0

失败情况如下，其他驱动加载工具同样会失败

 

 各种设置工程属性，全部无效，无奈，自己动手调试，最终定位到的问题为“CheckSum不匹配！！！”

 

 

真的不清楚开发环境为什么会出现这个问题，根据系统的算法自己实现了一个CheckSum计算工具，代码写的很丑，仅供参考（网上也有很多，也可已参考其他人的）
