If you own a powerful Windows 10 PC but Microsoft says it’s “not compatible” with Windows 11, don’t worry — you’re not alone. Many users around the world, especially in regions like the UK, have faced this frustrating barrier. But here’s the good news: You can bypass these restrictions and upgrade your PC to Windows 11, even on unsupported hardware, with your data intact.
This guide explains how to upgrade your Windows 10 machine to Windows 11 version 24H2 using a powerful third-party script called FlyByWin11. We’ll also address common errors, region issues, VPN workarounds, and data safety tips.
⚠️ Disclaimer:
This tutorial involves bypassing Microsoft’s official hardware checks. While many users have reported success, please proceed at your own risk and always back up your data before starting.
🛠️ What You’ll Need:
- A Windows 10 PC (preferably not older than 10 years)
- Stable internet connection
- A VPN (optional but helpful for region-specific errors)
- The FlyByWin11 upgrade script (official GitHub page: FlyByWin11 GitHub)
🧭 Step-by-Step: Upgrade to Windows 11 24H2 on Unsupported PC
✅ Step 1: Check System Readiness
Create a few dummy files on your desktop. These will help confirm that your data stays intact after the upgrade.
Next, download the FlyByWin11 script and extract it. If your antivirus (including Windows Defender) flags it, just click More info > Run anyway. This is a common false positive, as the tool modifies system behavior.
✅ Step 2: Use VPN if You’re Outside the U.S.
Many international users (especially in the UK or Europe) get region-based errors. Here’s how to fix that:
- Use a VPN and connect to a United States server.
- Open Settings > Time & Language > Region.
- Change your region to United States.
This step is crucial to bypass Microsoft’s installer restrictions.
✅ Step 3: Launch FlyByWin11 and Run Compatibility Check
- Open the script.
- It will check your hardware compatibility.
- 2 green checkboxes = Good to go.
- 1 or 2 red checkboxes = May still work, but risky.
If your PC is very old (e.g., originally shipped with Windows 7), it’s best to stick with Windows 10.
✅ Step 4: Download Windows 11 ISO
Within the script:
- Choose the English (United States) version.
- Select your architecture (most likely x64).
- Let it download the ISO — this might take a while.
❗ Important: Don’t install just yet.
✅ Step 5: Revert Region Settings
Once the ISO download completes:
- Go back to Settings > Region.
- Change your region back to United States (yes, keep it US for install).
✅ Step 6: Mount ISO and Start Upgrade
- Launch FlyByWin11 again.
- Select More Options > Select ISO from Computer.
- Choose the ISO file you just downloaded.
- The tool will mount the ISO and initiate upgrade setup.
You may see “Install Windows Server” — don’t worry. It’s just a generic setup name and works for Home/Pro versions too.
Continue through the prompts:
- Accept license
- Choose to Keep Files, Settings, and Apps
Let the installation begin!
🔁 Final Steps After Installation
- You should now be on Windows 11 (24H2).
- Your data and programs should be untouched.
- Head to Settings > Time & Language > Region and switch back to your original location (e.g., UK).
- Go to Settings > Windows Update and let it check for updates.
❓ Frequently Asked Questions (FAQs)
❓ Will I keep getting Windows Updates?
Yes, at least for now. Microsoft may restrict updates to unsupported PCs in the future, but as of now, updates work fine.
❓ What if the download links stop working?
Try again after 24 hours or use a VPN. Microsoft sometimes blocks traffic during spikes in demand.
❓ Why does my antivirus flag the tool?
Because the script modifies system behavior, some antivirus software shows a false alert. It’s safe to use if downloaded from the official GitHub.
❓ What if my drivers (Wi-Fi, Audio) stop working?
Go to your device manufacturer’s website and install the latest drivers compatible with Windows 11.
❓ Can I roll back to Windows 10?
Yes. Go to Settings > Recovery > Go back to Windows 10 — available for a limited time after upgrading (typically 10 days).
❓ What if I have red checkboxes in FlyByWin11?
Your hardware may be too old. While it may still install, issues are more likely. It’s safer to stay on Windows 10 or consider a hardware upgrade.
❓ Is FlyByWin11 safe?
Yes, but it’s third-party software. Always download it from FlyByWin11 GitHub and back up your data beforehand.
🧑🔧 Final Thoughts
Upgrading to Windows 11 on unsupported hardware is not just possible — it’s actually pretty smooth with the right tools. Thanks to the FlyByWin11 script and a few tweaks (like changing region settings), you can enjoy the latest features of Windows 11 24H2 even if Microsoft says your system is “not compatible.”
But remember: Backup is non-negotiable. Always protect your files before a major upgrade.
If it works for you, consider donating to the FlyByWin11 developer — they’ve made it possible for thousands to avoid buying a new PC unnecessarily.
