Microsoft officially restricts Windows 11 updates to PCs that meet its hardware requirements—like TPM 2.0 and newer CPUs. But if you’re using a Windows 10 machine with unsupported hardware and still want to upgrade, there’s a workaround: Flyby11.
Flyby11 is a lightweight tool that helps you bypass Windows 11’s hardware checks and upgrade anyway. This post shows you how to use it safely and effectively.
⚠️ Disclaimer: Forcing the update is unsupported by Microsoft. Proceed at your own risk and back up your data first.
🧰 What You’ll Need
- A Windows 10 PC (unsupported for Windows 11)
- An internet connection
- An 8GB+ USB drive (optional, for clean install)
- Flyby11 (free tool)
- Windows 11 ISO or Installation Assistant
🔽 Step 1: Download Flyby11
Flyby11 is available on GitHub and other developer forums. Make sure you’re downloading it from a trusted source.
- Search for Flyby11 GitHub or visit a verified software forum.
- Download the latest
.zipor.exeversion. - Extract the contents if needed.
⚙️ Step 2: Prepare for the Upgrade
You can use Flyby11 with either:
- Windows 11 Installation Assistant
- Windows 11 ISO (for a clean or in-place install)
Tip: Get the latest ISO from Microsoft’s official site for best results.
🚀 Step 3: Use Flyby11 to Bypass Requirements
- Run
Flyby11.exeas Administrator. - It will automatically patch registry settings and disable the TPM and CPU checks.
- Once it completes, do not reboot yet.
💻 Step 4: Start the Windows 11 Installation
Depending on your method:
Option 1: Use Installation Assistant
- Download and run the Windows 11 Installation Assistant.
- Proceed as normal. Flyby11 has already bypassed the hardware checks.
Option 2: Use ISO File
- Mount the ISO by right-clicking → Mount.
- Run
setup.exe. - Choose whether to keep your files or do a clean install.
- Continue with the on-screen prompts.
🔄 Step 5: Finish the Upgrade
Once the installer runs through, your system will reboot and complete the upgrade to Windows 11—even if your hardware is officially unsupported.
🛠 Optional: Post-Install Steps
- Check for updates:
Settings → Windows Update - Reinstall or update drivers if needed
- Consider disabling telemetry or updates if you want to avoid future compatibility issues
⚠️ Important Notes
- Microsoft may block updates on unsupported systems in the future.
- You won’t get official support, and stability may vary.
- Use this method only if you accept the risks and understand what you’re doing.
✅ Final Thoughts
Flyby11 is one of the simplest tools to force a Windows 11 install on unsupported hardware. If you’re not ready to let go of older yet still functional PCs, this can extend their usability—with caution.
