SHELLEXECUTEINFO 是Windows API ShellExecuteEx的参数，这个是一个结构体类型，里面可以添加参数，当IpVerb成员为 “runas”的时候可以提升启动进程的权限，如果不设置，会继承父进程的权限，ShellExecuteEx

std::string strOpEXEPath = _strOpEXEPath; SHELLEXECUTEINFO sei = { 0 };DWORD ExitCode = 0; // Initialize for ShellExecuteExsei.cbSize = sizeof(SHELLEXECUTEINFO);sei.fMask = SEE_MASK_NOCLOSEPROCESS;sei.lpVerb = "runas";sei.lpFile = strOpEXEPath.c_str();sei.lpParameters = strConfigINIFile2.c_str();sei.lpDirectory = NULL;sei.nShow = SW_HIDE; BOOL hr = ::ShellExecuteEx(&sei); if ((LONG)sei.hInstApp > 32){DWORD ResultWait = WaitForSingleObject(sei.hProcess, INFINITE);if (ResultWait == WAIT_TIMEOUT){TerminateProcess(sei.hProcess, 0);} GetExitCodeProcess(sei.hProcess, &ExitCode);CloseHandle(sei.hProcess);}
