Introduction

With Microsoft officially ending support for Windows 10 in October 2025, millions of users are facing a tough question: how can they upgrade to Windows 11 if their devices don’t meet the strict hardware requirements? Enter Flyby11 (also known as FlybyScript), a powerful open-source tool that has gained popularity for helping users bypass these limitations and upgrade to the latest version of Windows 11—even on unsupported hardware.

This article provides a complete guide to Flyby11, covering its features, how it works, step-by-step usage instructions, recent updates, and important precautions.

What Is Flyby11? Bypassing the Windows 11 Hardware Block

Flyby11 is a script-based tool developed by Belim, designed specifically to help users upgrade to Windows 11—even the latest 24H2 release—on devices that do not meet Microsoft’s official hardware requirements.

Windows 11 24H2 introduces several exciting features such as enhanced AI capabilities, built-in sudo commands, and Wi-Fi 7 support. However, Microsoft has also tightened its upgrade restrictions in this version, outright blocking certain legacy hardware and trying to patch traditional workarounds. As a result, tools like Flyby11 have become more essential than ever.

How Flyby11 Works: Core Features and Mechanism

Flyby11 relies on two main techniques to bypass hardware checks during the upgrade process:

  1. Server-Based Upgrade Method
    This method downloads the upgrade package from specific servers to perform the installation.
  2. Registry Modification Method
    If the server-based method fails, this fallback approach modifies registry settings to bypass the hardware checks.

⚠️ Note: Flyby11 does not support clean installations. It is built exclusively for upgrading existing Windows systems. For systems that already meet the hardware specs, the latest version of Flyby11 offers a direct upgrade option—faster than waiting for Microsoft to push updates via Windows Update.

Step-by-Step Guide to Using Flyby11

If you’re ready to use Flyby11 to upgrade to Windows 11 24H2, follow these steps:

  1. Download the Tool
    Get the latest version of Flyby11 from its official GitHub repository.
  2. Run the Program
    Extract the zip file and launch the Flyby11 application. If you encounter a Windows security warning like “Windows protected your PC”, click “More info” and then “Run anyway.”
  3. Allow Security Prompts
    Click Yes on all UAC (User Account Control) confirmation windows.
  4. Choose Your Upgrade Method
    Start with Method 1 (Server Setup). Be sure to enable the Fido script option, which is required to fetch the latest 24H2 ISO directly from Microsoft.
  5. Download and Install
    After the ISO is downloaded, select “Mount and run ISO”, then follow the on-screen instructions to complete the upgrade. If Method 1 fails, switch to Method 2 (Registry Modification).

What’s New in Flyby11: Features & Plugin System

Recent updates to Flyby11 have introduced several new features and a powerful plugin system:

  1. Direct Upgrade
    Devices that meet hardware specs can now skip Windows Update delays and upgrade instantly.
  2. Upgrade Status Check
    A new verification tool lets users confirm if Method 2 or direct upgrade options have been successfully enabled.
  3. Plugin System
    Flyby11 now supports ten helpful plugins, including:
    • Windows Old Remover: Deletes old Windows files to free up disk space.
    • OneDrive Remover: Removes OneDrive from the system.
    • Restore Built-in Apps: Restores default apps that may be removed during upgrade.
    • Create Restore Point: Creates a system restore point before upgrading.
    These plugins aren’t required for the core upgrade, but they greatly enhance the overall user experience and system cleanliness post-upgrade.

Important Precautions Before Using Flyby11

Before using Flyby11 to upgrade your system, keep these considerations in mind:

  1. Backup Your Data
    Always back up important files before upgrading.
  2. Hardware Compatibility
    While Flyby11 allows upgrading on unsupported devices, using hardware that closely matches Microsoft’s requirements is still recommended for best performance.
  3. Stability Risks
    Running Windows 11 on unsupported hardware may lead to feature limitations or system instability.
  4. Security Updates
    Microsoft could block unsupported devices from receiving future security updates.
  5. Alternative Tools
    Tools like Rufus also offer bypass options, but lack Flyby11’s plugin system and automation features.

Strengths and Limitations of Flyby11

Why use Flyby11?

✅ Streamlined Process: Automatically handles ISO downloading and upgrade execution—no need for manual scripting.
✅ Flexible Methods: Offers both server-based and registry-based upgrade paths.
✅ Plugin Support: Adds cleanup and recovery features that improve post-upgrade management.

But be aware of its limitations:

❌ No Clean Install Support: Only works for in-place upgrades, not fresh installs.
⚠️ Security Warnings: May be flagged by Windows Defender as potentially unsafe due to its system-level modifications.
❓ Future Uncertainty: Microsoft could implement stronger blocks in future updates, limiting Flyby11’s effectiveness.

Final Thoughts

Flyby11 is a powerful and user-friendly tool for upgrading to Windows 11 24H2 on unsupported hardware. With ongoing development, useful plugins, and an active user community, it provides a lifeline for those left behind by Microsoft’s tightening upgrade policies.

However, users should proceed with caution—back up your data, weigh the potential risks, and stay informed about future changes from Microsoft.
