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.

- 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

- Privacy-conscious Windows users
- Geeks who hate preinstalled apps and background services
- Users tuning a fresh install in one pass
Quick Start
- Download the exe from Releases, no install needed
- Create a system restore point first
- Tick the tweaks you want, each with a description and risk rating
- Apply the changes
- 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
