Advanced Windows 11 optimization and diagnostics companion.

It is not intended to replace common baseline tools such as CTT WinUtil or Winhance. Use those for broad setup and debloating, then use ZapTweaks for deeper gaming, latency, hardware, networking, graphics, power, diagnostics, and recovery workflows. Both companion tools can be launched or installed from ZapTweaks itself.

Highlights

• Fluent UI desktop app built for Windows 11.
• Advanced gaming, CPU, GPU, networking, timer, power, privacy, and shell controls.
• Hardware-aware availability for Intel, AMD, and NVIDIA systems.
• Apply/revert support and state verification for toggle-based tweaks.
• Restore-point gate for aggressive operations.
• Dry-run mode for command validation without system changes.
• Live CPU and RAM dashboard plus per-adapter GPU/VRAM readings, GPU selection, and explicit unavailable-data states.
• Bundled diagnostics, installers, scripts, power plans, and recovery tools.
• Built-in update checks with official-source validation, streaming download progress, and SHA-256/size verification before installation.
• App catalog refreshes from this repository without a new app release, with validated metadata, offline cache, and bundled fallback.
• Multi-app installation/uninstallation plans retain independent snapshots and rollback state.
• UI language selection for English, Italian, German, Spanish, French, Russian, and Simplified Chinese.
• 91 bundled power plans with import, activation, and previous-plan restore.
• Direct access to CTT WinUtil and Winhance for complementary baseline work.

Languages

The interface is available in English, Italian, German, Spanish, French, Russian, and Simplified Chinese. Select a language from Settings; the choice is saved locally.

Categories

• Home: live metrics and detected hardware.
• Gaming: latency and game-focused optimizations.
• Networking: TCP, adapter, offload, and power controls.
• Power & CPU: processor policies, boost behavior, timers, and power plans.
• Graphics: driver, display, flip-model, and GPU utility workflows.
• Windows: operating-system behavior and maintenance.
• System Checks: health checks and diagnostics.
• Refresh & Recovery: repair and recovery actions.
• Setup: post-install configuration tools.
• Advanced: expert-only and higher-impact operations.
• Privacy: telemetry and background-content controls.
• Visuals: shell and UI behavior.
• Tools: bundled utilities plus CTT WinUtil and Winhance.

Requirements

• Windows 11 22H2 or newer.
• Administrator privileges.
• x64 system.

Dependencies

• Flutter and Dart
• fluent_ui for the Windows 11 interface
• flutter_acrylic, bitsdojo_window, and system_theme for native window integration
• shared_preferences for local settings
• http for update checks
• path for filesystem paths
• flutter_test and flutter_lints for testing and analysis

Version constraints are maintained in pubspec.yaml.

Installation

Download the installer or portable package from GitHub Releases.

Install the latest release from an elevated PowerShell window:

irm https://raw.githubusercontent.com/PrimeBuild-pc/ZapTweaks/main/scripts/installer-latest.ps1 | iex

Catalog and update integrity

The app store, global search, and guided setup share a catalog fetched from this repository's main branch. Refresh the app inventory to check for catalog changes. Only validated app metadata, HTTPS links, and package identities are accepted; remote commands or scripts are rejected. A cached or bundled catalog remains available offline. External utilities show requirements/warnings where supplied and are not reported as installed or absent when their state cannot be detected.

The updater and PowerShell installer verify the exact official release asset, its size, and the SHA-256 digest supplied by GitHub's HTTPS release API before launch. The desktop updater also restricts redirects to GitHub asset hosts and rechecks the file immediately before execution. This is integrity verification against GitHub metadata, not Authenticode code signing. Releases include SHA256SUMS.txt for manual verification.

Safety

ZapTweaks exposes advanced settings that can affect stability, security, power use, and network behavior. Read each description, create restore points when requested, and avoid applying changes you do not understand. NIC and device power-saving toggles create a local backup before changing state. Remote-script actions display a warning before execution.

VBIOS and NVRAM tools are launcher-only: ZapTweaks does not bundle them, choose firmware images, or run flash commands. See THIRD_PARTY_NOTICES.md.

Build from source

flutter pub get
flutter analyze
flutter test
flutter build windows --release

The Windows CMake build copies the complete resources directory next to the executable. Create the portable package with:

./build_portable.ps1 -SkipFlutterBuild
