Lock Cursor Tools for Windows

Overview

Lock Cursor Tools is a lightweight, free utility for Windows created by Digola that keeps your mouse pointer confined to a chosen section of the desktop. It’s intended to stop accidental cursor movement between overlapping windows or across multiple displays, similar in purpose to utilities such as Cursor Lock or Mouse Lock.

Getting started and controls

Installation requires minimal disk space and uses very little RAM or CPU. After setup you can activate or deactivate the restriction using the default keyboard shortcut Ctrl + Alt + F12, or by clicking the program icon in the system tray.

Ways to restrict the pointer

• Choose a single monitor so the lock applies only to that display.
• Limit the restriction so it only takes effect when a particular program is active.
• Specify a pixel rectangle or draw a selection box on the screen to define the allowed area.

Known problem to watch for

A small number of users report that the cursor lock sometimes cannot be turned off when certain built-in Windows applications (for example, Notepad or File Explorer) are in use. In those cases the only workaround reported is terminating the Lock Cursor Tools process via Task Manager to restore normal pointer behavior.

Summary

Overall, Lock Cursor Tools is a handy, low-overhead utility for keeping the mouse pointer where you want it. It provides multiple ways to limit cursor movement and is easy to operate, though you should be aware of the sporadic compatibility issue with some native Windows apps before relying on it in critical workflows.
