Keyboard and Mouse Locker: How to Lock Your Input Devices Locking your keyboard and mouse without locking your screen is the best way to prevent accidental clicks while keeping your display completely active. While pressing Win + L safely locks down your entire Windows operating system, it completely hides your screen. Dedicated input lockers solve this problem by freezing your input hardware while your monitor continues to display videos, presentations, or video calls. Why Use an Input Locker?
Freezing physical inputs while leaving the desktop visible is highly useful across several common scenarios:
Toddler and Pet Protection: Prevent children or walking pets from interrupting a cartoon or closing open windows.
Hardware Cleaning: Wipe away dust and fingerprints from your hardware safely without triggering stray commands or deleting files.
Presentations and Live Demos: Play a video or run a slideshow securely during meetings without worrying about accidental bumps to the desk. The Best Software Tools to Lock Input Devices
Since Windows lacks a built-in toggle specifically for freezing inputs without signing out, lightweight third-party applications provide the easiest solution. 1. Keyboard & Mouse Locker (Windows Store App)
The dedicated Keyboard & Mouse Locker app on the Microsoft Store provides a modern, clean interface built specifically for Windows.
How it works: It allows you to freeze inputs individually (keyboard only, mouse only, or both together) via a minimal system tray control.
The Unlock Mechanism: Users can set a custom global hotkey combination (such as Ctrl + Alt + Key) to toggle the lock instantly. 2. KeyFreeze
KeyFreeze is a completely free, lightweight classic utility designed to quickly block your inputs.
How it works: Running the standalone program initiates a brief countdown before completely disabling mouse clicks and keystrokes.
The Unlock Mechanism: Pressing the universal shortcut Ctrl + Alt + F restores regular peripheral functionality immediately. 3. Padlock
For open-source utility enthusiasts, the lightweight Padlock utility on GitHub offers precise control over peripheral input states.
How it works: It runs quietly in the system tray and supports specialized operational layers, including a completely blocked mode or a restricted mode.
The Unlock Mechanism: Users trigger the lock using Alt + L and can instantly exit the freeze by typing a customizable string sequence. Built-In System Alternatives
If you prefer not to install dedicated utilities, you can achieve similar results using alternative methods:

You can manually disable components directly through the operating system: Right-click the Start menu and open Device Manager.
Expand the Keyboards or Mice and other pointing devices dropdown list.
Right-click your active peripheral and select Disable device (Note: Built-in laptop keyboards may only offer an Uninstall option, which reinstalls upon reboot). Filter Keys Accessibility Shortcut
Windows includes a built-in safety fallback called Filter Keys that can deliberately slow down or ignore brief keystrokes:
