🐝 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 1.42

• 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.
