Using administrator user to execute a program from C# RRS feed

  • Question

  • I've got a problem executing a c# code which executes other c# program, it has to open with an administrator user. It works fine in windows 8 but when i want to execute it in windows 10 it says that the user or password is wrong. Maybe, the way you log in  windows 8 is  differently with win 10. In this following code you will have to change it to open a document or image(as you wish) the thing is that you have to open it with cmd and the administrator user.

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Threading.Tasks;
    using System.Windows.Forms;
    using System.DirectoryServices;
    using System.Diagnostics;
    using System.IO;
    using System.Security;
    namespace Ejecutable
        static class Program
            /// <summary>
            /// Punto de entrada principal para la aplicación.
            /// </summary>
            static void Main()
                     string cmdPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.System), "cmd.exe");
                    string workingDirectory = @"C:\Users\Desktop";
                    string pathToFile = Path.Combine(workingDirectory, "distri2017.pdf");
                    string arguments = string.Format("/c start {0}", pathToFile);
                    var password = new SecureString();
                    foreach (char c in "password")
                    var processStartInfo = new ProcessStartInfo()
                        FileName = cmdPath,
                        Arguments = arguments,
                        WorkingDirectory = workingDirectory,
                        UserName = "ADMINISTRATOR",
                        Domain = Environment.MachineName, // Could use domain
                       Password = password,
                        UseShellExecute = false,

                catch (Exception e)
                    MessageBox.Show("COULDNT OPEN: "+e);

    No it is not different. If the credentials being given are wrong, then they are wrong.

  • Have you verified that the Administrator account in Windows 10 is enabled?

  • I suggest that you make another admin account on Win 10 and test it.

  • Yes, the account is correct in win 10

  • Yes, the account is correct in win 10

    So if you make a new admin account and it works, then what?

  • Hi JoseHHS,

    Do you use a different administrator user? does it work for you?

    If the issue still exist, please feel free let us know.
