Impersonating in Windows (WinForm)

Impersonating in asp.net is as simple as just adding a tag in web.config but in windows I found few links which were using kernel dll to impersonate. Article I found on theserverside.net shows new features in .net 2.0 which makes it very easy to do this.

Quote:

System.Diagnostics.ProcessStartInfo pInfo =   new System.Diagnostics.ProcessStartInfo();

            SecureString ss = new SecureString();

                          ... append password characters

            pInfo.Password = ss;

            pInfo.UserName = @"domain\alice";

            pInfo.FileName = @"c:\windows\notepad.exe";

            pInfo.UseShellExecute = false;

            Process.Start(pInfo);
