WPF: Kill Windows GUI (explorer.exe) and then restore it

Question

What I want to do is to kill the explorer.exe main process (which will result in killing the Windows gui programatically and then open the gui again. I can achieve that by manually killing and then starting the process through taskmanager, but I can't figure out how to do kill the main explorer process from a wpf visual C# program. Also, I tried killing it from taskmanager and then starting the windows gui again by:

var proc = new Process
            {
                StartInfo = new ProcessStartInfo
                {
                    FileName = "explorer.exe",
                    Arguments = "",
                    UseShellExecute = true,
                    CreateNoWindow = true
                }
            };
            proc.Start();

but it only starts a new explorer window, not the windows gui. Can someone help me to kill the win gui and start it again with some code, please?

Answer 1

I finally managed to find out the solution: killing the explorer.exe by getting the process and using Kill() only restarted the gui. To completely shut it down, use

        var proc = new Process
        {
            StartInfo = new ProcessStartInfo
            {
                FileName = "taskkill.exe",
                Arguments = "/F /IM explorer.exe",
                UseShellExecute = true,
                CreateNoWindow = true
            }
        };
        proc.Start();
