optimizerDuck
Free, open-source Windows optimization tool for performance
...It gives users a single interface for applying researched Windows tweaks without manually editing the registry, services, scheduled tasks, or system settings. The tool targets common sources of overhead, including telemetry, unwanted background services, preinstalled app behavior, conservative power settings, and latency-related defaults. It includes performance, privacy, GPU, power, bloatware, service, and user-experience optimizations with descriptions and risk ratings. optimizerDuck runs as a single executable with no installer, and it includes backup and revert systems for safer experimentation. It is most useful for Windows users who want a guided way to debloat, tune, and reverse system changes from one place.
