<div class="hero-glow-divider"></div>
<p class="intro-description lead-text"><strong>Looking for a screen lock for Windows PC?</strong>
This
Windows screen lock builder creates a portable screenlocker (.exe) with your own custom
message and password protection. If you need to lock your Windows PC screen with a custom
message, this screen lock software provides a simple and secure solution.</p>
<p class="intro-description">
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 PC screen locker or advanced security features, this builder has you
covered.
</p>
<p class="intro-description">
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.
</p>
<p class="intro-description">
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.
</p>
<p class="intro-description">
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.
</p>
<p class="intro-description">
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.

<!-- FAQ Section -->
<div class="faq-section">
<h3>Frequently Asked Questions</h3>
<div class="faq-container">
<div class="faq-item">
<h4>Is this software safe to use?</h4>
<p>Yes! Screen Lock Builder uses AES-256-GCM encryption to protect your password.</p>
</div>
<div class="faq-item">
<h4>Will this work on my Windows version?</h4>
<p>Screen Lock Builder works on Windows 7, 8, 10, and 11. The generated .exe files are
portable and don't require installation on the target computer.</p>
</div>
<div class="faq-item">
<h4>What happens if I forget my password?</h4>
<p>Unfortunately, if you forget your password, there's no way to recover it due to the
strong encryption. We recommend writing down your password in a secure location or
using a password manager.</p>
</div>
<div class="faq-item">
<h4>Is the generated .exe file detectable by antivirus?</h4>
<p>Some antivirus programs may flag the .exe file as suspicious due to its screen
locking behavior. This is normal for security software. You can add an exception or
whitelist the file if needed.</p>
