Mouse Jiggler is a free and simple Windows utility tool that simulates mouse movements. In doing so, it will help prevent programs that launch upon inactivity, like your screensaver, from running. Mouse Jiggler is a handy utility that keeps your computer awake without you needing to touch the mouse.
Why use Mouse Jiggler?
Windows usually launches your screensaver or goes into a default power-saving mode after a certain period of inactivity. This puts your computer to sleep or turns off the display altogether. Of course, you can manually adjust these settings, but it can become arduous when you only need modified settings for intermittent tasks.
A simple solution
This Windows tool essentially fools your computer into staying awake. It’s useful when you want to watch a movie, listen to music or perform and monitor other time-consuming actions. The app lets you do such tasks without your screensaver or power-saving mode interrupting you.
How it works
You don’t need to install Mouse Jiggler as it's a portable program. After downloading the .zip file, simply unzip it and run the MouseJiggle.exe file. A dialogue box will pop up where you can check the ‘Enable Jiggle’ box to start using it. The application will now visibly move your cursor on-screen. You can then minimise the dialogue box by clicking the Down arrow button.
Modes and settings
You can also select ‘Zen Mode’, which performs the same task without moving your cursor. The application remembers your settings for every session, but you can adjust these with command-line options. To disable Mouse Jiggler, you can uncheck the ‘Enable Jiggle’ or ‘Zen Mode’ box.
Mouse Jiggler alternatives
The app seems to work perfectly on Windows, but there are plenty of alternatives. Caffeine simulates a keypress to prevent screensaver or standby mode from kicking in. However, it has more options and controls for a tailored experience. Insomniate performs the same task and has a standard version with a timer, while PreventTurnOff offers multiple preferences.
No more interruptions
Mouse Jiggler is a simple yet effective Windows tool. By ‘faking’ mouse movements, it prevents annoying sleep or screensaver modes from interrupting you. Once downloaded, you can use it instantly - no installation required. However, if you want a utility with more functionality, Caffeine, Insomniate and PreventTurnOff are popular alternatives.
