Download BlueLife KeyFreeze v1.4 – Lock Keyboard and Mouse with One Click

BlueLife KeyFreeze v1.4 is a tiny portable utility for Windows that lets you instantly lock your keyboard and mouse with a single keyboard shortcut. This is useful when you need to clean your keyboard, let a child watch something on screen without accidentally pressing keys, or step away briefly without locking your entire session.

When activated, the screen remains visible and active — only keyboard and mouse input are blocked. No password or login is required to unlock; simply press the same hotkey combination again to resume normal input. The tool sits quietly in the system tray and has virtually no impact on system resources.

BlueLife KeyFreeze requires no installation and leaves no traces on your system. It is a true plug-and-play utility that anyone can use without configuration.
