Reset Windows Administrator Account Password in C#

How to Reset Windows Administrator Account Password in C# (Silently)

Introduction

By using this technique you can reset the Windows Administration Account password to what ever you want. In addition, with some changes, you can also reset other Windows Account passwords. However, the most importent point of this technique is that the method runs silently (hidden) and does not show the CMD Window. I hope this is useful to you!

Using the code

Just copy and paste the following code into your Project.

C#
using System.Diagnostics; 
//
private static void ResetAdminPass(string NewPass)
{
    //Create New Process
    Process QProc = new Process();

    // Do Something To hide Command(cmd) Window
    QProc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
    QProc.StartInfo.CreateNoWindow = true;

    // Call Net.exe
    QProc.StartInfo.WorkingDirectory = "C:\\windows\\SYSTEM32";
    QProc.StartInfo.FileName = "net.exe";
    QProc.StartInfo.UseShellExecute = false;
    QProc.StartInfo.RedirectStandardError = true;
    QProc.StartInfo.RedirectStandardInput = true;
    QProc.StartInfo.RedirectStandardOutput = true;

    // Prepare Command for Exec
    QProc.StartInfo.Arguments = @" user administrator " + NewPass;
    QProc.Start();

    // MyProc.WaitForExit();
    QProc.Close();
}
//

For example you can create a Windows Forms Application (C#) and in Form_Load() do this:

C#
private void Form1_Load(object sender, EventArgs e)
{
    ResetAdminPass("12345ABC");
}

Note that you can simply change "administrator" to what ever you like and reset that account instead.

Points of Interest

I use this code snippet in my project to help my clients so that each time they change their password in my program, their Windows Administrator Account password changes, too!

I hope this is useful to you!
