又㕛后续补充
莫名其妙重启了几次系统后，又出现了该问题，同时驱动不能加载了，呵呵呵呵，驱动装好之后，我什么都没干过(2019/04/02)
又后续补充
在最新的系统更新后，该问题消失(2019/04/01)
后续补充：
该问题并不影响驱动安装和驱动的正常工作！！。。
win10给一个驱动程序打签名，签名阶段无异常，/v /kp验证之后提示 SignTool Error: The signing certificate is not valid for the requested usage.
具体错误如下

SignTool Error: The signing certificate is not valid for the requested usage.检查了2个证书，增强用法均包含内核签名用法1.3.6.1.5.5.7.3.3，所以证书是没问题的
最后发现问题出在win10操作系统，不知道这个系统抽了什么疯，在其他版本系统验证没问题。
