optimizerDuck
Free, open-source Windows optimization tool for performance
...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.
