Screen Lock Builder

Looking for a screen lock for Windows? This Windows screen lock builder creates a portable screen locker (.exe) with your own custom message and password protection. If you need to lock your Windows screen with a custom message, this tool provides a simple and secure solution.

Perfect for families who want to control and limit computer usage time, or for security purposes in various environments such as offices, schools, or public terminals. Whether you need a basic screen lock Windows tool or advanced security features, this builder has you covered.

You can customize the lock screen message, protect it with an encrypted password, and even define restrictions such as disabling Task Manager, blocking Command Prompt, or enabling auto-startup on system boot.

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.

An optional auto-close feature allows the lock screen to automatically release at a specific date and time — giving you full control over when and how the lock behaves.

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.
