Keyboard Blocker

Keyboard Blocker is a lightweight Windows utility that completely disables keyboard input while running in the background. Ideal for preventing accidental keystrokes – when a child watches a movie or during a presentation.

Once launched, it places an icon in the system tray and blocks all keys. To unblock, type word "unblock", use the tray menu, (right‑click the icon). The blocking state is saved between sessions. A second launch only shows the current status near the clock.

Features

Full keyboard blocking
System tray integration
Single‑instance enforcement
Auto-start with Windows
