淳朴C++代码实现瞬间关机，没有包含任何函数库。不需要任何头文件支持。直接shellcode实现了动态调用RtlAdjustPriviladge和NtShutdownSystem，附带int 0x2E。:)-Honest C++ code to achieve an instant shutdown, does not contain any libraries. Does not require any header file support. Direct shellcode achieve

快速关机，实现3秒内强制关机，发送ntshutdownsystem的原理。-Fast shutdown, force shutdown of 3-seconds, sending ntshutdownsystem principle.

调用NtShutdownSystem快速关机-Fast Shutdown call NtShutdownSystem
