What is it?

optimizerDuck is a WPF desktop app for Windows 10 and 11 (x64 and ARM64) that groups common system tweaks into one interface. Its optimizations cover performance, privacy, GPU, power, bloatware and services, user experience, and AI features such as Windows Recall, each labeled with a risk rating before it is applied.

Beyond the tweaks, the app includes a system dashboard, a startup manager, a scheduled task browser, a disk cleanup tool, and a bloatware remover that lists removable AppX packages. A separate Customize section offers toggles for desktop icons, taskbar, File Explorer, and gaming settings without editing the registry directly.

Every change writes a revert file to a local folder, so individual tweaks or all changes can be undone from the UI. The app runs as a single .exe without installation, requires administrator rights, and is licensed under GPL v3.
