Works starting with windows XP, not available in win 2000 or lower: This is the quickest way to do it: Process.Start(“shutdown”,”/s /t 0″); Otherwise use P/Invoke or WMI like others have said. Edit: how to avoid creating a window var psi = new ProcessStartInfo(“shutdown”,”/s /t 0″); psi.CreateNoWindow = true; psi.UseShellExecute = false; Process.Start(psi);
As CommonsWare already said that this is not possible in an Ordinary SDK Application. You need to sign your app with the System Firmware Key. But it’s possible for your app with Root privileges.
