What this system is

Flyoobe is a Windows desktop application designed for system optimization and privacy hardening, allowing users to disable telemetry, ads, and bloatware through registry-based toggles. It provides a unified interface for managing Windows 11 installation sources and executing optional setup actions like power plan configuration. The tool also includes legacy utilities for Windows 11 upgrade compatibility and system repair.

Features

Initial release of Flyoobe privacy and performance features

This commit introduces the initial set of configuration features for the Flyoobe tool, allowing users to disable Windows advertising, telemetry, and bloatware, as well as optimize system performance. The new files in the Ads, Edge, Gaming, and System directories implement registry-based toggles to disable File Explorer ads, personalized ads, lock screen tips, and Microsoft Edge features like the shopping assistant and default browser prompts. Additionally, it adds options to disable Game DVR, power throttling, and visual effects for gaming performance, along with system tweaks such as disabling hibernation and showing detailed Blue Screen of Death (BSOD) error codes.

Users can now apply a wide range of system tweaks categorized under System, MS Edge, UI, Gaming, Privacy, and Ads, with specific features including disabling telemetry, location tracking, and various Windows ads. The application also provides an installation view allowing users to manage Windows setup sources via providers like Rufus, MCT, and Ventoy, and includes one-click actions for quick repairs and USB creation.

Optional Setup Actions and legacy Windows 11 upgrade tools

Users can now install optional 'Setup Actions' (such as preflight checks, icon cache clearing, and power plan configuration) by placing the Actions folder in the application's Data directory and enabling the feature in Settings. Additionally, legacy Windows 11 upgrade compatibility tools, including a native CPU check library and the Flyby11 upgrade assistant UI, have been added to the legacy directory.

Behavioural changes

Flyoobe 3 release notes and repository restructuring

The repository has been restructured to highlight Flyoobe 3, including a new CHANGELOG.md that details the addition of local PowerShell-based Setup Actions, a redesigned interface with native Windows controls and Windows 7-inspired aesthetics, and various UI fixes. The README.md has been updated to reflect the new Flyoobe branding, provide official download links, and issue security warnings about impersonating websites. Additionally, a .gitattributes file was added to configure language detection for C and C++ source files, and a new Visual Studio solution file (Flyoobe.sln) was introduced.

How this codebase got here

This is the PUBLIC form of this artifact. Findings are listed in full, but the details of SECURITY findings — which rule fired, in which file, on which line, and how to fix it — are deliberately withheld, and any secret-scanner results are excluded entirely. Where detail is absent here it was REMOVED FOR PUBLICATION; it is not missing from the analysis. The complete artifact is available from the repository owner.

builtbybel/FlyOOBE was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point a surveyor at a repository you know and see whether you agree with it.

About this page

  • The score is its most recent published measurement, taken on 23 September 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit b2d9d2133d012639f0c0cd7fcfb7472189fe4786 — the exact code this score is about.
  • Scored under rubric-2026.09.15 — the same rubric and the same method as every other entry in this index.
  • Measured by watchdog.canine.dev using codehealth-analyzer preprod-955b9cee9818.
