WinLock - Windows AppLocker

WinLock is a professional-grade, minimalist security utility for Windows 11. It is designed to protect specific applications (Browsers) with a modern passcode interface that feels native to the OS. Built with Python and CustomTkinter, it features a Windows 11 Fluent Design UI that automatically adapts to your system's Light or Dark mode.

Important

The default password is 1234 if you have mistakenly run the project without seeing the documentation.

✨ Features

• Strict Lockdown: Full-screen solid UI prevents unauthorized viewing, minimizing, or Alt-Tabbing until the correct PIN is entered.
• Adaptive UI: Seamlessly switches between Light and Dark mode based on your Windows system settings.
• Individual App Security: Smart tracking allows you to lock Chrome, Edge, Brave, and Opera individually. Unlocking one does not automatically unlock the others.
• Win+L Protection: Integrated with Windows system calls; automatically re-locks all protected applications the moment you lock your Windows workstation.
• Auto-Startup Service: Self-registers in the Windows Registry to start automatically in the background upon login.
• Session-Based Memory: Once unlocked, a browser stays open until you close it or lock your PC.
