Project Overview

optimizerDuck is a free, open-source Windows optimizer focused on performance, privacy and simplicity: background services, telemetry, preinstalled apps and scheduled tasks that ship with a fresh install can all be handled without digging through Registry, Group Policy or PowerShell.

It offers 42 system tweaks in 7 categories (performance, privacy, GPU, power, bloatware and services, UX, AI), 44 customization settings in 4 categories, plus built-in tools for a system dashboard, startup manager, scheduled tasks, disk cleanup and bloatware removal with risk badges; portable, just run the exe.

Item Value
Platform Windows 10+ (x64 and ARM64)
Stack C# / .NET
Scale 42 tweaks + 44 settings + 5 built-in tools
License GPL-3.0

Registry and Group Policy switches become one-click toggles with risk labels.

Key Features

  • Performance: service-host tuning based on RAM, process priorities, keyboard latency and multimedia scheduler tweaks
  • Privacy: disables telemetry, error reporting, advertising ID, location tracking, Cortana, Copilot and content suggestions
  • GPU: vendor-specific registry tweaks for AMD, NVIDIA and Intel covering power states and display latency
  • Power: hibernation and fast startup off, USB selective suspend off, a custom high-performance plan
  • Bloatware and services: blocks OEM app reinstall and tunes startup types for 200+ services
  • AI switches: disables Windows Recall snapshots and the Click To Do overlay
  • Customization: 44 toggles for desktop icons, taskbar, gaming, context menu and more
  • Built-in tools: system dashboard, startup manager, scheduled tasks, disk cleanup and bloatware removal with risk badges

Target Audience

  • Gamers squeezing more from older PCs
  • Privacy-conscious Windows users
  • Geeks who hate preinstalled apps and background services
  • Users tuning a fresh install in one pass

Quick Start

  1. Download the exe from Releases, no install needed
  2. Create a system restore point first
  3. Tick the tweaks you want, each with a description and risk rating
  4. Apply the changes
  5. Restart when convenient

Core Advantages

  • Transparent risk: every tweak carries a clear description and rating before you apply
  • Proven sources: tweaks come from widely used tools, nothing AI-generated or blind-added
  • Portable: a single exe, run anywhere
  • Reversible: paired with restore points, every change can roll back

System Requirements

Item Requirement
OS Windows 10 or later
Architecture x64, ARM64
Runtime .NET (latest)

Notes

  • Restore point first: the project recommends a system restore point before any change
  • Choose wisely: some privacy and service tweaks affect system features, tick by need
  • .NET required: a supported .NET runtime must be installed
