Answer 1

STARTUPINFO si;
PROCESS_INFORMATION pi;
ZeroMemory(&si, sizeof(STARTUPINFO));
ZeroMemory(&pi, sizeof(PROCESS_INFORMATION));if (CreateProcess(NULL ,"Main.exe",NULL,NULL,FALSE,NORMAL_PRIORITY_CLASS|DETACHED_PROCESS,NULL,NULL,&si,&pi) == 0)
{
DWORD ad = GetLastError();
return;
}

TerminateThread(pi.hThread, 0);
