🎉 v1.0.0 - Initial Stable Release

I am incredibly proud to announce the very first stable release of SecureAppLocker (v1.0.0)! 🚀

This release marks the culmination of meticulous development, complex architecture design, and rigorous testing. SecureAppLocker is built to provide a robust, fail-secure, and lightweight application locking experience for Windows, seamlessly bridging a SYSTEM-level NT Service with a beautifully modern WinUI 3 interface.

⚠️ CRITICAL: Read Before Installing

  1. Default Master Password: Upon first launch, the manager and prompts will require a master password. The default password is 1234. Please change this immediately in the settings and backup your offline recovery key!
  2. Uninstall Password: During the setup process, the installer will ask you to create an Uninstall Password. This is a permanent, SHA-1 hashed security measure to prevent unauthorized removal of the software from your system. Do not lose it!

✨ Key Highlights of v1.0.0

  • Fail-Secure Architecture: If the password prompt UI is forcefully closed or crashes, the background service enters Lockdown Mode, instantly killing the target application to ensure zero data leaks.
  • Smart Metadata Detection: Bypassing the locker isn't as simple as renaming an .exe. The engine hooks into the internal OriginalFilename and ProductName metadata to identify applications accurately.
  • Active Process Immunity: Intercepts newly launching apps without aggressively killing your active work. Once an app is unlocked, its main executable and child processes are granted temporary immunity.
  • Zero-Trust Session Lock: Integrated directly with Windows Terminal Services (WTS). Pressing Win+L to lock your Windows session instantly wipes all active app unlock caches.
  • Adjustable Micro-Polling: You have full control over the process scanning interval (down to 50ms) for the perfect balance between CPU performance and millisecond-level interception.
  • Master Protection Switch: A global toggle on the WinUI 3 dashboard to instantly arm or disarm the entire locking system for heavy workflows or gaming sessions.
  • Session-Independent IPC: Bulletproof communication between Session 0 (NT Service) and Session 1 (User UI) using Named Pipes.

🐛 Known Behaviors

  • Startup Synchronization Delay: The SYSTEM service starts protecting your PC the second it boots. However, the UI prompt starts with your user login. If you launch a locked app immediately upon seeing the desktop, it will be killed instantly, but the password prompt might take a few extra seconds to appear while Windows loads background startup apps.

📥 Installation

  1. Download the SecureAppLocker_v1.0.0_Setup.exe from the Assets below.
  2. Run the installer (Requires Local Administrator privileges).
  3. Set your custom uninstall password.
  4. Open SecureAppLocker Manager, log in with 1234, and start securing your digital workspace!
