FlyOOBE is the natural evolution of Flyby11.
The classic Flyby11 upgrader still exists and is included inside FlyOOBE,
plus it's also available as a separate download if you only want the minimal upgrade tool.
Originally, Flyby11 was a simple patcher to remove the restrictions stopping you from installing Windows 11 (24H2) on unsupported hardware.
Old PC? No TPM, no Secure Boot, unsupported CPU? Flyby11 let you install Windows 11 anyway.
After helping thousands upgrade, one thing became clear:
Bypassing checks is only half the battle.
We needed a full setup solution — one that respects user choices instead of Microsoft's defaults.
FlyOOBE was the next step:
Skip the fluff
Remove the junk
Take full control from first boot
Because your PC should work for you, not the other way around.
FlyOOBE keeps the original idea alive and pushes it even further.
Flyby11/FlyOOBE uses known, currently working methods to bypass Windows 11 24H2 restrictions.
