Why are you starting explorer in a command window, why not just start it direct? Also, explain what happens in your login program after starting this process.

Hi,

Check this one

C#

using System.Runtime.InteropServices;


  private void button1_Click(object sender, EventArgs e)
        {
        
            string cmd = "/C explorer.exe ";
            System.Diagnostics.Process.Start("CMD.exe", cmd);
            DisplayStartMenu();
           
        }

        private static void DisplayStartMenu()
        {
            // key down event:
            const byte keyControl = 0x11;
            const byte keyEscape = 0x1B;
            keybd_event(keyControl, 0, 0, UIntPtr.Zero);
            keybd_event(keyEscape, 0, 0, UIntPtr.Zero);

            // key up event:
            const uint KEYEVENTF_KEYUP = 0x02;
            keybd_event(keyControl, 0, KEYEVENTF_KEYUP, UIntPtr.Zero);
            keybd_event(keyEscape, 0, KEYEVENTF_KEYUP, UIntPtr.Zero);
        }

        [DllImport("user32.dll")]
        static extern void keybd_event(byte bVk, byte bScan, uint dwFlags,
           UIntPtr dwExtraInfo);
