BOOL ShutDownWindows(UINT t)
{
  OSVERSIONINFO osv;  //定义一个操作系统信息的结构体
osv.dwOSVersionInfoSize=sizeof OSVERSIONINFO;
GetVersionEx(&osv);   //查询当前操作系统
  if(osv.dwPlatformId==VER_PLATFORM_WIN32_NT)  //判断是否是2000/NT
{
  //下面为向操作系统获取权限操作
HANDLE hProcess,hToken;
TOKEN_PRIVILEGES Privileges;
LUID luid;
hProcess=GetCurrentProcess();
//下面为打开当前进程对话
OpenProcessToken(hProcess,TOKEN_ADJUST_PRIVILEGES,&hToken);
Privileges.PrivilegeCount=1;
LookupPrivilegeValue(NULL,SE_SHUTDOWN_NAME,&luid);
Privileges.Privileges[0].Luid=luid;
Privileges.Privileges[0].Attributes=SE_PRIVILEGE_ENABLED;
AdjustTokenPrivileges(hToken,FALSE,&Privileges,NULL,NULL,NULL);
ExitWindowsEx(t,0);
}
