FlyOOBE 2.4
🐝 FlyOOBE – Guided Setup & Upgrade Experience for Windows
Side project plug
Try Winslop, a cheeky Windows 11 cleanup/tweaks tool, inspired by the whole “Microslop” era and Nadella’s “slop vs sophistication” line
FlyOOBE 2.4 is here!
Happy New Year 🎉
As we head into 2026, I want to say thank you to everyone using and supporting FlyOOBE.
In 2025, FlyOOBE reached nearly 2.5 million downloads on (only) GitHub and became one of the most popular and requested tools for Windows 11.
Your feedback, issues, and ideas helped shape the project throughout the year.
Let's see if we can do it again in 2026.
Changelog
“We need to get beyond the arguments of slop vs sophistication…” - Satya Nadella
Agreed, but users still deserve a choice!!! The AI OOBE control has been refined and is now officially called Slopilot.
Slopilot isnt anti-AI - it's pro user choice
- This update improves detection of AI-related (Slopilot) features across Windows 11 and adds optional deep cleanup capabilities via external tooling such as RemoveWindowsAI.
Users can now better understand, review, and disable AI components they dont want, transparently and on their own terms - Improved browser detection in the Browser OOBE
- Updated Extensions engine for better coverage and accuracy
- Global search functionality expanded and refined across all sections
- Improved theme detection in the Personalization OOBE
- Minor core optimizations and internal cleanups

FlyOOBE 2.3
🐝 FlyOOBE – Guided Setup & Upgrade Experience for Windows
Note for returning users:
❗ Important:
Flyby11 is now FlyOOBE (pronounced “fly-oh-bee”) - yeah, it sounds like a buzzing bee, but really its all about that smooth OOBE (Out-Of-Box Experience)fight!, uh flight! 🐝🚀
FlyOOBE is the next evolution of Flyby11.
You can still grab the classic Flyby11 (upgrade only) if you prefer,
or switch to FlyOOBE for the full upgrade + OOBE/Tweak/Debloat toolkit.
Same developer, same quality – just more options.
FlyOOBE 2.3 is here!
- I mentioned this in the last FlyOOBE release: I’m going to take care of CrapFixer as well. The plan now is to connect both apps a lot better, because CrapFixer is simply better at some things than the OOBE part inside FlyOOBE and vice versa, FlyOOBE is still the all-rounder.
For quick debloating though, CrapFixer is the better tool, so it’ll be taking over a few modular functions. especially some of FlyOOBE’s advanced/extended stuff. I’m announcing that here in FlyOOBE now, and the upcoming CrapFixer release will learn about it too. So this release lays the foundation for FlyOOBE ↔ CrapFixer interconnect. Internal structures were prepared so both apps can communicate and share modular functionality more cleanly going forward - Laid the groundwork for a multilingual UI.
No promises on timing yet. Im not sure when I’ll get to it, or whether CrapFixer or FlyOOBE will get it first. It's a lot of tedious work… you probably believe me 😄

FlyOOBE 2.2 is here!
- Polished the action buttons with a modern compact mode: show icon + label by default, then switch to a sleek icon-only look while active (just like native Windows 11 apps)
- Further sped up app startup and trimmed memory usage, not that it was ever a bloated XAML/WinUI monster like the Windows 11 Start menu or Explorer… but hey, every millisecond counts (yes, Im currently at war with Microsofts performance choices. Maybe one day theyll fix real performance issues instead of adding another glowing Copilot button. And honestly, it hurts watching an OS you once loved slowly being run into the ground by the wrong priorities and decisions; lets see how long it takes until they manage to chase me away to another shore as well)
- Flyby11 is back in its classic outfit inside FlyOOBE: the UpgradeOOBE (Flyby11) UI has been simplified and brought closer to the original look, while the built-in Autopilot has been upgraded to guide you more autonomously through the Windows 11 installation
Note: The ConsumerESU script from https://github.com/abbodi1406/ConsumerESU/
is currently unavailable on GitHub (either removed or temporarily blocked, similar to a past false-positive suspension that also briefly affected my own profile)
Spent so much time and energy on FlyOOBE that I almost forgot about my old buddy CrapFixer. Its definitely due for a glow-up as well, if you dont know it yet, check it out here: https://github.com/builtbybel/CrapFixer, basically CCleaner 2.0 from the golden Windows XP era.

FlyOOBE 2.1 is here!
Well,i'll admit it: I really dont like leaving things half-finished.
So after spending the last few days locked at home with a stubborn cold, I decided to put that time to use fueled by way too much hot chocolate… ehm, coffee ;)
Somewhere between caffeine, code, and questionable sleep schedules, FlyOOBE 2.0 went from "Preview chaos" to something unexpectedly stable and actually quite nice.
This release marks a major milestone, not just a redesign, but a redefinition
FlyOOBE has grown from a simple OOBE setup assistant into a true all-in-one Windows companion.
With the new modular engine, extensions are evolving into mini-apps within the app, offering powerful customization, automation, and personalization tools for Windows 11.
Some OOBE pages have already transformed into fully functional mini-apps themselves and a few names might sound familiar to long-time users, like Dumputer or CoTweaker.
(Those were once standalone apps… I'm not entirely sure what happened to them, but now their lightweight successors live on inside FlyOOBE's setup pages)
It's cleaner, smarter, and more unified, a platform slowly becoming an all-round control and enhancement hub for both enthusiasts and everyday users.
Well then… good night for now, at least for the next few hours 😅
What's new in 2.1
The UI introduced back in version 2.0 has now been fully finalized and cleaned up once more. The main form hasn’t looked this polished in a long time. You can now seamlessly switch between the OOBE and Extensions.
Going forward, the focus will shift even more toward Extensions, so a clean UI arrives at just the right time.
- Several debloating/cleanup modules have been bumped to a higher tier and now dig up even more (and even deeper) AI-infused junk. Still no AgenticOS takeover in sight- but with Microsoft’s latest moves… let’s just say: enjoy the peace while it lasts ;)
- Memory usage reduced even further
- Fixed various DPI-related issues
- Optimized extension loading
- Extensive code refactoring
The full source code for v2 will be pushed soon

What's new in 2.0
- Modernized and simplified Interface: cleaner, more focused, and less overwhelming, making the initial setup much easier for new and casual users
- Improved perfomance: The app is faster and more responsive, with reduced loading times and better resource management
- Extensions engine completely reworked under the hood, now using a new internal filtering system with a category dropdown.
- A brand-new app icon finally featuring a smart, friendly little bee inside 🐝 (I might've cheated a bit and let AI help with that one 😉)
- Improved global search and refresh behavior for smoother control updates across views
- New centralized Home dashboard that intelligently categorizes and recommends OOBE setup pages and extensions. Many items are now discoverable via keyword tags. (The first experimental Copilot integration has been temporarily removed while refined.)
- Large-scale refactoring and transition to primarily asynchronous processing. Search, filtering, and loading operations no longer cause UI hangs
- New back navigation system with a full stack-based history, allowing you to rewind through previous pages just like in a browser
- Extensions shipped with the app can now also be uninstalled just like user-added ones
- New native activity monitor logs system actions in real time and can provide contextual help for extensions (when supported).
- Improved UI scaling and clarity on high-DPI displays
- New indexing system for all OOBE pages and extensions based on metadata, allowing tools like Flyby11 to be found using simple keywords such as ESU, 10, or 11
- New modern Copilot-inspired designs can now be found in the settings menu
- Extensions.md has been updated accordingly
- Dozens of Minor Fixes and Quality Improvements

Through extensions and user-created modules, FlyOOBE is becoming a kind of all-in-one Windows 11 control and enhancement hub – lightweight, extensible, and built for power users and casual users alike.
The new UI is more streamlined, less overwhelming, and makes the initial setup flow much easier for new or casual users.
What’s new in the UI:
- Reduced complexity with fewer menus and visual clutter
- Cleaner layout with more breathing room
- Clear primary actions to keep guidance obvious
- Less text, more direction, less cognitive overload
- Overall a much friendlier first-time setup experience
- This matters, because an OOBE assistant should be something you can complete without prior knowledge or technical experience.
And for the community who uses FlyOOBE for modding, tweaking, and experimenting:
Those possibilities stay and continue to expand through extensions, custom scripts, and future modules.
I'd love for the community to try it out and share feedback while this Preview evolves.
More improvements coming soon.
See you in the next build 👋

FlyOOBE 1.51
🐝 FlyOOBE – Guided Setup & Upgrade Experience for Windows
Note for returning users:
❗ Important:
Flyby11 is now FlyOOBE (pronounced “fly-oh-bee”) - yeah, it sounds like a buzzing bee, but really its all about that smooth OOBE (Out-Of-Box Experience)fight!, uh flight! 🐝🚀
FlyOOBE is the next evolution of Flyby11.
You can still grab the classic Flyby11 (upgrade only) if you prefer,
or switch to FlyOOBE for the full upgrade + OOBE/Tweak/Debloat toolkit.
Same developer, same quality – just more options.
What's new in 1.51
- The extensions system has been improved again. The PowerShell-based engine has been expanded, and Flyby11 (UpgradeOOBE.exe) is now included as a native extension within FlyOOBE. On Windows 10 systems, a dedicated upgrade tile will appear on the home dashboard, allowing users to launch the Windows 11 upgrade workflow directly, with help instructions included
- Extensions now also display their author or source, such as Flyby11 by Belim or the ViVeTool-bridge by Albacore. This adds transparency and helps users understand where each tool originates from. This feature will be expanded further in future updates, and developers who wish to share their own scripts or tools will be able to integrate them into FlyOOBE more easily.
- Updated Extensions docs
- This update improves FlyOOBE’s behavior on some high-resolution displays. Several UI scaling issues on 4K screens and Windows scaling levels above 200% have been fixed. Elements such as tiles, layout spacing, and navigation now scale consistently and no longer overlap.

What's new in 1.50
- Background rendering rework: The background selection feature introduced in the previous version has been reworked for better performance and stability.
You can now select a background style via Settings > Pick background
The old image-based handler was replaced with an internal gradient-based renderer.
This removes issues with locked image files, unreleased GDI objects, and redundant event handlers.
The update significantly reduces memory usage and improves rendering speed and overall UI responsiveness - Added support for script-driven input fields for the Extensions engine via # Input: true and # InputPlaceholder: Uses positional args for maximum compatibility, with optional console / silent / log host modes, status + progress, and a clean placeholder UX.
- New Extension script: ViVeTool Bridge
Wrapper to enable/disable/query hidden Windows features by ID. Supports comma-separated ID lists - New Extension script: Ninite Bulk Installer
Builds the Ninite bundle URL from app slugs/names, downloads to Desktop (predictable filename), and launches Installer - New Extension script: Winget Bulk Installer
Quickly installs multiple packages in one run (IDs separated by space/comma/newline) - Online Update Checker redesigned in full retro style, think Windows 2000 meets GameBoy 😆
- Updated Extensions docs

What's new in 1.42
-
Split the upgrade tool out
- FlyOOBE was tightly coupled with the upgrade/bypass tool Flyby11 (aka UpgradeOOBE). I’ve completely detached UpgradeOOBE (the Windows 10 → 11 migration assistant) from FlyOOBE
- FlyOOBE now focuses 100% on customizing Windows 11
- UpgradeOOBE (Flyby11) focuses only on upgrading to Windows 11 and runs as a standalone app
- Safety-first separation: Due to false positives from security tools, this split was the obvious next step. If Microsoft or other AV solutions ever flag something again, only UpgradeOOBE can be affected. FlyOOBE will remain untouched. Currently there are no detections and FlyOOBE is not classified as harmful or a hack tool.
-
Community input
- I’m running a poll about FlyOOBE’s future design direction.
- Even though WinUI + Windows App SDK would blow up the app size (a WinUI build would be ~333× larger than the current WinForms app), I'll keep the poll open and continue iterating on the current version.
-
Modernization & polish
- The current release got a UI refresh and new features
- You can now pick a background image (see intro video)
- Brand-new App Settings view
- Improved update process
- Reinstall OOBE page renamed to Advanced
- Menu reorganized and simplified
-
UpgradeOOBE (Flyby11) specifics
- Fully standalone, does not require FlyOOBE (and vice versa)
- Depends only on CpuCheckNative.dll, which can be removed to allow upgrade attempts on unsupported CPUs (SSE4.2 still required in practice)
-
Under the hood
- Large-scale code refactors
- Prep work for more extensive OOBE pages
- UI and navigation tweaks to make things cleaner and more intuitive
-
Future considerations
- Possible FlyOOBE Lite edition that ships without the Extensions/Scripts folder by default — PowerShell scripts are commonly abused by fileless malware, so a light build could be safer for some users.
- Potential option to download official scripts on demand from GitHub (like a mini store), rather than bundling them.
