实现自定义gina接口，设计与winlogon.exe的交互:

开发原理：依赖Microsoft默认的gina dll:msgina.dll，在本dll中导入msgina.dll导出的接口，在本dll的导出接口中，保持大部分接口与msgina.dll操作的一致性，改变WlxLoggedOnSAS接口的响应，使系统在登陆成功的状态下，不响应Ctrl+Alt+Del-realize GINA interface definition, design and interactive winlogon.exe : Development Principle : Microsoft on the default GINA dll : msgina.dll, in this dll Introducing msgina.dll derived interface, the interface is derived dll's, most maintain msgina.dll interface with the operation of consistency, change WlxLoggedOnSAS interface response, allowing the system to the successful landing of the state, do not respond to Ctrl-Alt-Del
