Do you have an older PC that Microsoft says can’t run Windows 11 24H2? Missing TPM, Secure Boot, or your CPU isn’t on their approved list? Don’t worry — Flyby11 (also known as FlybyScript) is here to help.

With Flyby11, you can easily bypass those pesky hardware restrictions and install the latest Windows 11 24H2 build on unsupported hardware. No technical wizardry needed — just click, patch, and install.

🚀 What Is Flyby11?

Flyby11 is a lightweight, open-source patching tool designed to remove Windows 11 hardware restrictions, allowing you to install the OS on virtually any PC that meets the bare minimum for booting.

✅ No TPM?
✅ No Secure Boot?
✅ Unsupported processor?

Flyby11 makes it possible anyway.

Think of it as the “backdoor key” to installing Windows 11 24H2 on older or technically unsupported devices — all while staying aligned with Microsoft’s documented workarounds.

🔍 How Does Flyby11 Work?

Flyby11 takes advantage of a clever trick involving the Windows Server setup variant, which skips hardware compatibility checks. Here’s the breakdown:

🧠 Technical Overview:

• Uses Windows Server Setup: This skips checks for TPM, Secure Boot, and unsupported CPUs.
• Installs Regular Windows 11: You still get a normal Windows 11 experience, not a server edition.
• Automates ISO Download & Mounting: Optionally uses Fido script to get the latest ISOs for you.
• Handles Everything Automatically: No manual Registry edits, no Media Creation Tool hacks, no messing around with script errors.

It’s fast, clean, and remarkably reliable.

💻 How to Use Flyby11 (Step-by-Step)

1. Go to the Official GitHub Page
   👉 Flyby11 on GitHub
2. Download the Latest Release
   • On the right sidebar, click Releases.
   • Download the latest .zip file and extract it to a folder.
3. Run the Tool
   • Launch Flyby11.exe (or the PowerShell script version).
   • If prompted, run as administrator.
   • The tool will automatically guide you through patching the installer or downloading the ISO.
4. Start the Installation
   • Once patched, the Windows 11 setup will launch without compatibility checks.
   • Install as normal.

🟢 If you’re using version 2.3 or later, Flyby11 will also check if your CPU supports the required POPCNT instruction (see below).

🧬 POPCNT CPU Requirement

Windows 11 24H2 now requires the POPCNT CPU instruction, which cannot be bypassed. Most CPUs made after 2010 support it — but if yours doesn’t, Flyby11 will warn you before proceeding.

If you see two green checkmarks, you’re good to go! If not, your hardware is simply too old to run 24H2, and there’s no known workaround.

🧾 Why Use Flyby11?

• ✅ Keep your older hardware alive
• 🌱 Reduce e-waste by reusing what you already own
• 💸 Save money by avoiding unnecessary upgrades
• ⚙️ Clean patching process without registry hacks or complex scripts

FAQ

Will my unsupported PC still get Windows Updates?

Yes, in most cases — though Microsoft may eventually block updates for unsupported configurations. So far, most users continue to receive cumulative and security updates as usual.

Is this legal?

Flyby11 uses techniques described in official Microsoft documentation for bypassing hardware checks on upgrades. It doesn’t tamper with licensing or activate pirated Windows.

Is it safe?

Yes, but as with any system modification:

• Backup your data
• Understand what you’re doing
• Read any tool warnings carefully

✅ Final Thoughts

Flyby11 makes installing Windows 11 24H2 on unsupported PCs as easy as clicking a button. Whether you’re a tinkerer, a budget user, or just someone who wants to breathe new life into older hardware, this tool gets the job done — fast and clean.
