Download FlyOOBE App →

FlyOOBE solves the number one problem preventing millions of users from upgrading to Windows 11: incompatible hardware.

If you have been blocked by TPM 2.0, CPU generation, or other hardware compatibility requirements, FlyOOBE bypasses these restrictions automatically.

Before upgrading, you may want to read our guide on whether you should upgrade to Windows 11 on unsupported hardware to understand the benefits and potential risks involved.

What FlyOOBE Does: FlyOOBE leverages Windows 11's server installation variant to skip hardware compatibility checks entirely.

Unlike manual registry edits or risky workarounds, FlyOOBE automates the entire process safely through Microsoft's own bypass mechanisms.

If your PC meets the requirements but you prefer a manual approach, the official Windows 11 Installation Assistant provides a straightforward upgrade path.

Key Features

Automatic ISO Download and Mounting - No manual file handling required. FlyOOBE downloads the official Windows 11 ISO directly from Microsoft servers and mounts it automatically.

Hardware Bypass Technology - Skip TPM 2.0, CPU, and RAM requirements that would otherwise block your installation. The tool modifies installation parameters without touching your system files.

Custom OOBE Experience - Enhanced Windows setup with advanced customization options lets you configure privacy settings, remove preinstalled apps, and set up local accounts during installation.

System Debloating Tools - Remove unwanted Windows 11 components instantly. Strip out telemetry services, preinstalled apps, and unnecessary features before your first boot.

24H2 and 25H2 Compatibility - Fully updated for the latest Windows 11 releases including the newest feature updates.

PowerShell Script Support - Add your own automation scripts to customize the installation process further.

Alternative Installation Methods

While FlyOOBE handles the entire upgrade process automatically, some users prefer creating bootable installation media.

Rufus includes built-in Windows 11 bypass options and creates bootable USB drives in minutes - check our detailed guide on how to install Windows 11 on unsupported hardware using Rufus for step-by-step instructions.

For users who need multiple operating systems on a single USB drive, Ventoy offers a unique approach where you simply copy ISO files to the drive without reformatting. This makes it easy to keep Windows 10, Windows 11, and Linux installers ready on one device.

If you want to create a portable Windows installation that runs directly from an external drive, WinToUSB specializes in Windows To Go configurations that travel with you.

Why Choose FlyOOBE

Originally developed as Flyby11, FlyOOBE represents four generations of Windows 11 bypass technology.

Thousands of users have successfully upgraded unsupported PCs using these tested, reliable methods. The tool includes both upgrade assistance and post-installation optimization, giving you complete control over your Windows 11 experience from start to finish.

Unlike standalone bypass tools, FlyOOBE combines multiple utilities into one interface. You get the hardware bypass, ISO management, OOBE customization, and system debloating without switching between different applications.

After Your Upgrade

Once Windows 11 is installed on unsupported hardware, you may encounter driver compatibility issues.

Snappy Driver Installer Origin maintains offline driver packs that work perfectly on systems where manufacturer support is limited. The tool automatically finds compatible drivers even when your hardware vendor has stopped providing Windows 11 updates.

For system information and hardware verification, CPU-Z provides detailed specifications about your processor, motherboard, and memory configuration.

System Requirements

• Any PC currently running Windows 10.
• 4GB or more available storage space.
• Internet connection for ISO download.

Note that Windows 11 24H2 and 25H2 require POPCNT and SSE4.2 CPU instructions which cannot be bypassed by any tool. FlyOOBE version 2.4 includes a compatibility checker that warns you if your processor supports these required instructions.

What's New in FlyOOBE Version 2.4

This update is especially important for everyone still on Windows 10 who plans to stay there and take advantage of the Extended Security Updates (ESU) program.

The interface has been modernized and simplified with a cleaner, more focused design that makes initial setup easier for new users. Performance improvements deliver faster loading times and better resource management throughout the application.

The extensions engine has been completely reworked with a new internal filtering system and category dropdown. A centralized Home dashboard now intelligently categorizes and recommends OOBE setup pages and extensions, with many items discoverable via keyword tags.

Large-scale refactoring transitions the application to primarily asynchronous processing, so search, filtering, and loading operations no longer cause interface hangs. A new back navigation system with full stack-based history lets you move through previous pages like a browser.

Additional improvements include better UI scaling on high-DPI displays, a new activity monitor that logs system actions in real time, and the ability to uninstall extensions that ship with the app.
