This is a very old project — I originally built the first version back in 2015 ( VBnet). I've decided to revive it and completely modernize it.
Dev-offcode Windows Screen Locker's answer:
Fully Customizable Lock Message You can set your own message that appears on the lock screen, making it useful for public computers, shared family PCs, or training kiosks.
Strong Security (AES-256-GCM Encryption) The generated executable encrypts the password with strong AES-256-GCM encryption, making it much harder to bypass or reverse-engineer.
Portable Executable The tool creates a portable .exe file that requires no installation, allowing you to run it from a USB drive or deploy it on multiple machines easily.
Offline Operation The lock screen works entirely offline, meaning it doesn’t depend on the internet or any cloud service, which increases privacy and reliability.
Control Over System Features You can disable Task Manager and block Command Prompt, reducing the risk that someone bypasses the lock by killing the process or using system tools.
Auto-Start and Auto-Close The lock screen can be configured to start automatically on system boot and close on a schedule, making it ideal for labs, kiosks, or shared computers where access is restricted to specific times.
Folder Locker, Program Locker, and File Locker in One Unlike other tools, this builder combines folder locking, program locking, and file locking all in the same application, giving you full control over what can be accessed.
Schedule Lock Screen Times You can set the exact time for when the lock screen starts and ends, which is a unique feature compared to competitors.
Ransomware / Malicious Message Protection The builder includes a blacklist to prevent malicious or ransom-style messages, reducing the risk of misuse.
Free Tier Available A free plan offers basic customization, encryption, portable exe, and auto-close timer, so you can try it without cost.
Dev-offcode Windows Screen Locker's answer:
Individuals or families who want to control PC usage or restrict access at specific times.
Educational institutions such as schools or training centers that use shared computers or kiosks.
Small businesses that need simple security for shared or public terminals without deploying full enterprise solutions.
IT enthusiasts or administrators looking for portable, offline, and customizable locking options for specific projects or setups.
Users seeking combined folder, program, and file locking in one tool, along with scheduling options for when the system can be accessed.
Essentially, the audience is anyone who values strong security, offline operation, and flexible customization for Windows systems, particularly in environments where multiple users share the same machine.
