You can pre-run the hidden process taskmgr.exe

ProcessStartInfo psi = new ProcessStartInfo(System.IO.Path.Combine(Environment.SystemDirectory, "taskmgr.exe"));
psi.RedirectStandardOutput = false;
psi.WindowStyle = ProcessWindowStyle.Hidden;
psi.UseShellExecute = true;

processTaskMgr = Process.Start(psi);
