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 achieved dynamic invocation RtlAdjustPriviladge and NtShutdownSystem, with int 0x2E. :)
