MouseJiggler 3.0.0 by ArkaneSystems is a minimalist system utility designed to prevent screensavers, sleep mode, or auto-lock mechanisms from activating by simulating minuscule mouse movements. The application sits in the system tray and, when toggled on, sends tiny horizontal and vertical deltas to the Windows cursor, convincing the operating system that a flesh-and-blood user is still present. Because the jiggles are imperceptibly small, on-screen work is not disrupted, making the tool valuable for lengthy downloads, unattended presentations, remote-desktop sessions, or corporate environments where rigid group-policy timeouts would otherwise interrupt workflow. The codebase is intentionally lightweight—only one published version (3.0.0) exists—so no background updater or bundled framework is required, keeping CPU usage near zero and eliminating any network chatter. Users typically launch the portable executable only when needed, click “Enable,” and leave the PC; the pointer drifts a pixel or two every few seconds, resetting idle counters in Windows, Teams, Zoom, Citrix, or any other watchdog that relies on GetLastInputInfo. The utility is especially popular among technicians who run disk checks, VPN tunnels, or cloud-sync jobs overnight, as well as office workers forced to comply with aggressive 5-minute screen-lock policies. Being freeware with no installer, it can also be carried on a USB stick for ad-hoc deployment on locked-down machines where additional software cannot be permanently installed. MouseJiggler is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
