Quick Start

1. Download from GitHub Releases
2. Run the .exe directly, no installation required
3. Choose the optimizations you want, apply them, and restart your PC when you're ready

[!TIP] Always create a system restore point before making changes.

What optimizerDuck Does

Windows itself is fine. But a clean install also comes with services, telemetry, pre-installed apps, and scheduled tasks you've probably never heard of, all quietly running in the background, consuming your CPU, RAM, and disk. At the same time, some features that could actually help you get the most out of your hardware aren't enabled by default.

optimizerDuck gives you a single interface to clean up the bloat and unlock the good stuff.

It applies targeted system tweaks to reduce overhead and block unwanted behavior, and bundles several management tools so you can see what is running, remove what you do not want, and revert any change if something goes wrong.

[!NOTE] Every optimization can be applied manually. optimizerDuck just makes it easier for you to apply these optimizations.

System Optimizations

Over 30 tweaks across 6 categories, each with a clear description and risk rating so you know exactly what each change does before applying it.

Category	What it covers
Performance	Service host tuning based on your RAM, process priority adjustments, keyboard latency reduction, and multimedia scheduler tweaks for smoother gaming
Privacy	Disable Windows telemetry, error reporting, advertising ID, location tracking, Cortana, Copilot, and content delivery suggestions
GPU	Vendor-specific registry tweaks for AMD, NVIDIA, and Intel GPUs, covering power states, clock gating, and display latency
Power	Disable hibernation and fast startup, turn off USB selective suspend, install a custom high-performance power plan, and disable power throttling
Bloatware & Services	Block OEM app reinstall behavior and fine-tune startup types for 200+ Windows services
User Experience	Remove menu show delays, disable visual effects like taskbar animations and transparency for a snappier feel

[!NOTE] The optimizations here are researched from well-known tools with large user bases, nothing is AI-generated or blindly added. Every tweak is chosen for real-world impact.

Customize

No need to dig through the registry, just toggles, dropdowns, and number inputs presented in one place. Organized into four categories:

• Desktop: Show or hide icons (This PC, Recycle Bin, Network, User Files, Control Panel), remove shortcut arrow overlays
• Preferences: Taskbar alignment, widgets, Task View and End Task buttons, clock seconds, dark mode, file extensions, hidden files, clipboard history, compact view, snap assist, item checkboxes, classic context menu, and Bing search
• Gaming: Game Mode, Game Bar, background recording, mouse acceleration, fullscreen optimizations, hardware-accelerated GPU scheduling
• System: Enable Num Lock on boot

Built-in Tools

Tool	What it does
System Dashboard	View your CPU, RAM, GPU, storage drives, and OS details in one panel
Startup Manager	See every app and task that launches at boot, toggle them on or off, and open their file location
Scheduled Tasks	Browse, run, stop, enable, disable, or delete Windows scheduled tasks
Disk Cleanup	Scan and clear temp files, system cache, Windows Update leftovers, prefetch, thumbnails, recycle bin, crash dumps, and old Windows installations
Bloatware Remover	Lists all removable AppX packages with risk badges (Safe, Caution, Unknown), so you can pick what to remove

Safety

Changing system settings carries risk. optimizerDuck is built around reversibility and user control.

See the Privacy Policy for details on our data practices.

• Automatic backups: Every change writes a revert file to a local folder. You can restore individual tweaks or roll back everything
• One-click revert: Undo any applied optimization from the UI with a single click
• Risk ratings: Each tweak is labeled Safe, Moderate, or Risky based on its potential impact
• No defaults applied: Nothing runs until you select it. The tool does not enable anything on its own
• Restore point prompt: Before your first optimization, the app suggests creating a Windows restore point

FAQ

Is optimizerDuck safe to use?

Yes. optimizerDuck is fully open-source (GPL v3), meaning anyone can inspect, audit, or build the source code themselves. Every release is built automatically by GitHub Actions from the public source; no hidden modifications, no unsigned binaries injected after build. If you prefer, you can clone the repo and build the .exe yourself with a single dotnet build.

The app does not collect any telemetry, usage data, or personal information. See the Privacy Policy.

Does optimizerDuck actually improve performance, reduce latency, or speed up my network?

It can help. Every optimization in optimizerDuck is researched from well-known tools, community guides, and hardware vendor recommendations, nothing is AI-generated, blindly added, or made up. Each tweak addresses a real setting that Windows configures conservatively by default (e.g., service host grouping, GPU power states, network throttling, process scheduling).

There are no fake registry hacks here, every change has a documented purpose and real-world impact backed by community testing and vendor documentation.

Why does Windows SmartScreen / Defender flag the download?

optimizerDuck is not code-signed because code signing certificates are expensive for open-source projects. When Windows encounters an unsigned executable downloaded from the internet, SmartScreen displays a warning by default. This is normal and does not mean the file is unsafe.

To bypass, click "More info" > "Run anyway". If you are still concerned:

• Build the .exe yourself from source
• Submit the binary to online sandboxes like ANY.RUN for independent verification

Can I revert changes if something goes wrong?

Yes. Every optimization creates a revert file before applying. You can undo individual tweaks or roll back everything from the UI with one click. The app also suggests creating a Windows System Restore point before your first optimization.

Does this work on Windows 10 and Windows 11?

Yes. optimizerDuck supports Windows 10 (x64) and Windows 11 (x64).

Do I need administrator rights?

Yes. optimizerDuck modifies system settings and the Windows registry, so it requires administrator privileges to run.

Does optimizerDuck collect my data?

No. The app contains zero telemetry, analytics, or phone-home functionality. It runs entirely offline and does not send any data anywhere.

Why does Task Manager show 100% CPU after applying the power plan? (#29)

A known Task Manager display bug triggered by non-default power plans, it incorrectly reports 100% CPU on some systems while actual load is normal. Visual only, does not affect real performance or cause overheating. If unwanted, simply toggle off this optimization.
