How to send the admin password to windows cmd

Question

I have the code below in . Net written in Visual Studio 2019, which activates windows. The problem is that when running windows propmpt command running with an AD admin account it asks for the password, and this I am not able to send by program/code. Someone could help in this situation?

System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo.FileName = “cmd.exe”;
proc.StartInfo.Arguments = “runas /user:dominio\usuario slmgr.vbs -ipk aqui serial”;

proc.StartInfo.UseShellExecute = true;
proc.Start();

Answer 1

If the user who is running the application has the privilege of admin just declare the verb "runas"... but you can pass the authentication credentials with the domain on ProcessStartInfo also.

And to run the process with the credentials it is necessary to configure the UseShellExecute as false

    var senhaSegura = new System.Security.SecureString();
    var senha = "senhaDoUsuario";

    foreach (char c in senha)
        senhaSegura.AppendChar(c);



    var process = new System.Diagnostics.Process();
    process.StartInfo = new ProcessStartInfo
    {
        FileName = "cmd.exe",
        UserName = "usuario",
        Domain = "dominio",
        Password = senhaSegura,
        Verb = "runas",
        Arguments = "slmgr.vbs - ipk aqui serial",
        UseShellExecute = false
    };
    process.Start();
