How to Install Windows 11 on Unsupported CPU
When Microsoft unveiled the Windows 11 update, it was immediately evident that not all Windows 10 devices would meet the criteria for upgrading. Even after the company adjusted some of the system requirements to be less restrictive, numerous older systems—and particularly their processors—remain incompatible.
Suppose your computer falls into this category. Is there still a way to install Windows 11? That’s exactly what this guide aims to walk you through.
How to Install Windows 11 on an Unsupported CPU
If you're someone who isn't eligible for a straightforward upgrade to Windows 11 but are aware that Microsoft will discontinue support for Windows 10 in October 2025, you might be asking whether it's possible to upgrade without purchasing new hardware. Let’s explore how.
You Could Still Be Eligible
Even if your device doesn’t appear to meet the official Windows 11 requirements, it may still be capable of running the OS. In some cases, Microsoft’s compatibility checker flags components that aren’t strictly necessary for functionality. These include:
- Secure Boot
- CPU or TPM requirements
Some hardware, especially older CPUs, aren't officially supported—even though they can handle the operating system just fine.
Enter Fly by 11
Thankfully, third-party tools exist to bypass these restrictions. One such free tool is “Fly by 11,” which allows installation of Windows 11 even in server environments. It’s available at no cost and comes with its own compatibility assessment feature—offering an alternative to Microsoft’s PC Health Check—to help determine if your system can realistically run Windows 11.
Upgrading Using Fly By 11
To get started with “Fly by 11” (also referred to as “FlyObee”), follow these steps:
Step 1. Go to GitHub and download the latest version of the tool as a zip file.
Step 2. Extract the contents of the zip folder and launch the “Flyby11.exe” file.
Step 3. The tool will perform its own system check. If both “CPU POPCNT” and “SSE4.2” show green checkmarks, your system is likely capable of handling Windows 11.
Step 4. Click the “Start Upgrade Now!” button to initiate the upgrade process.
Step 5. The next screen will prompt you to select the Windows 11 ISO file. You can either download it directly via the tool from Microsoft, Fido, or use the user-friendly Media Creation Tool. Choose your preferred source from the dropdown menu.
Step 6. If using Fido, you can pick your desired version of Windows 11—such as the 24H2 update—from a dropdown list.
Step 7. After clicking “Continue,” you'll see additional configuration details. Make sure to select a Windows version in the same language and regional format to preserve your current settings.
Step 8. Once everything is set, click “Download,” and the ISO will be saved to your computer.
Completing the Installation with Fly By 11
Now that the ISO is downloaded and the tool is ready, proceed with the installation:
Step 1. Use the dropdown menu and select “Select from computer” to locate the downloaded ISO file on your system.
Step 2. A PowerShell window will open and begin the installation process. Rest assured, it will install the correct version of Windows 11 you selected.
Step 3. During setup, make sure to check the box labeled “Download updates, options, and additional features” before clicking “Next” to ensure you get the latest improvements.
Step 4. Agree to the license terms and choose the option “Keep files, settings, and apps” to retain your personal data and configurations.
Step 5. Hit the “Install” button to start the upgrade.
Step 6. Your computer will now begin installing Windows 11.
