What optimizerDuck is

optimizerDuck is a free, open-source Windows utility for adjusting system settings related to performance, privacy, and everyday use. Its tweaks cover areas such as GPU, power, services, user experience, and Windows AI features, with descriptions and risk ratings to help users review each change. A separate Customize section offers controls for desktop icons, the taskbar, File Explorer, and gaming settings. The app also includes a system dashboard, startup and scheduled task managers, disk cleanup, and a bloatware remover. It runs locally as a portable executable, keeps configuration on the device, and does not need internet access for core functions, though some optimizations use online resources. Documentation says applied changes can be reversed to restore the previous system state. The privacy policy says normal operation does not collect or transmit personal information or listed telemetry and identifiers. It supports Windows 10 and Windows 11 (64-bit, x64), requires administrator privileges for optimizations, and needs at least 100 MB of free system-drive space. The solo-developed project is GPL-3.0 licensed.
