Features

MouseUtil is a free and open source lightweight Windows utility that keeps your mouse "active" by clicking or jiggling/moving in place, so your PC doesn't go idle, lock, or sleep during long calls, downloads, or AFK sessions. It runs natively on Windows 10/11 (WinUI 3 / .NET 8) with a clean, minimal interface.

Core features

• Two automation modes — Auto click, which sends a real left-click at a set interval, or Spin mode, which sweeps the cursor in a tiny circle and returns it to its exact starting pixel.
• Configurable interval — set the delay between actions in minutes and seconds.
• Pause on manual movement (in Spin mode) — if you touch the mouse yourself, MouseUtil automatically pauses and resumes on a fresh countdown once you stop, so it never fights you for control.
• Auto-stop conditions — stop the run automatically after a set number of clicks/spins, or at a specific date and time.
• Global hotkey — start or stop automation from anywhere with a single keypress (F6 by default), even while another app is focused.
• Live status and progress — a real-time countdown ("Clicking in 12s"), action counter, and an optional progress bar mirrored onto the taskbar icon, all of which are optional.
• System tray support — optionally close the window to the tray instead of exiting, so automation keeps running in the background.
• Fluent design with light/dark/system theming.
• Persisted config file, so your interval, mode, hotkey, and preferences are remembered between sessions.
