Execute a system command from C#

Question

My program must be executed immediately after Windows's login screen. For this purpose, I have changed some registry values and now this program launches on start-up instead of Explorer.exe (). In my program, users enter their username and password and then login to system. After login, I want to run explorer.exe, taskbar, and start menu to become visible to user. I use this code to execute system command:

string cmd = "/C explorer.exe ";
System.Diagnostics.Process.Start("CMD.exe", cmd);

But after executing this command, just the My Computer window appears. Taskbar and Start Menu do not appear. How can I see Taskbar and Start Menu after executing the explorer.exe command (I use Windows 7)?

The proper (and only!) way to do customized login is via the Credentials Provider (post Vista) or using Gina (pre-Vista). Read Create Custom Login Experiences With Credential Providers For Windows Vista for an explanation how to do it.
