MouseJiggler is a straightforward utility designed for Windows that simulates mouse movement to prevent your computer from entering idle mode. This free tool effectively 'jiggles' the mouse pointer back and forth, ensuring that your screen stays active even when you are not physically using the mouse. With a simple interface, it allows users to easily enable or disable the jiggling effect as needed.

This program is particularly useful for individuals who require their computers to remain awake during extended periods of inactivity, such as when watching videos or running long processes. The lightweight nature of MouseJiggler ensures it does not consume significant system resources, making it a practical addition to any Windows utility toolkit.
