This premium screen locker for Windows creates portable executables with advanced capabilities including folder protection, website blocking, program locking, and scheduled automation. If you need a powerful screen lock Windows solution, this is the professional-grade tool you've been looking for.

Perfect for families who want to control and limit computer usage time, businesses requiring advanced security, or IT professionals managing multiple workstations. Whether you need to lock Windows screen for parental control, office security, or public terminal management, this premium edition delivers enterprise-level features.

The built-in blacklist protection (148+ words, 38 regex patterns) ensures that malicious ransomware-style messages cannot be used, making it a safe and responsible tool for legitimate screen locking purposes.

Premium Edition extends the core functionality with advanced features: save and load your configurations for easy deployment, lock folders and programs, block specific websites, schedule automatic startup, customize the UI with themes, protect the builder itself with a password, remove branding, and receive all future updates.

This is a very old project — I originally built the first version back in 2015. I've decided to revive it and completely modernize it.
