C# Windows Form Application: SafeNet System

Overview

Welcome to the SafeNet System Windows Forms application! SafeNet is a lightweight Windows Forms application that creates a secure, locked environment on a Windows machine. It disables access to essential system functionalities, including Task Manager, keyboard shortcuts (e.g., Ctrl+Alt+Del, Alt+Tab, WinKey), and desktop interaction, until the correct password is entered.

This tool can be used to simulate kiosk-mode behavior or as a simple educational project for understanding Windows security, registry manipulation, and system hooks in C#.

Features

Disables Task Manager via Windows Registry edits

Blocks system-level shortcuts like:

• Ctrl + Alt + Del
• Alt + Tab
• WinKey
• Ctrl + Esc

Hides the Windows taskbar and desktop icons

Unlocks system access only when the correct password is

Password is securely stored in a file (safenet.pass) and validated at runtime

How It Works

• When the application launches:

1. System Access is Locked:

• Task Manager is disabled.
• Windows key, Alt+Tab, and other escape shortcuts are blocked.
• Desktop icons and the taskbar are hidden.
• The form appears without borders, taking over the screen.

2. Login Prompt:

• A password prompt appears.
• The password is checked against the contents of safenet.pass.

3. On Correct Password:

• Task Manager is re-enabled.
• Desktop icons and taskbar are restored.
• Application exits, returning full control to the user.

Default Password

• The file safenet.pass should contain your password on a single line. Default password: "password" Warning: Do not use this tool in production or shared environments without further security hardening.

How to Use

1. Clone or download the repository.
2. Open the project in Visual Studio.
3. Build and run the project.
4. A password prompt will appear. Use the default password or modify safenet.pass before launching.
5. After entering the correct password, the system is unlocked.
