**Update – If you want to stay on Windows 10 past the October 2025 end of support date, Microsoft is now offering you three ways to extend your Windows 10 support until October 2026.
The time is upon us where Windows 10 will no longer be supported by Microsoft and you will be forced to either upgrade to Windows 11, stay on an unsupported operating system, or move to a new OS such as Linux or macOS.
Many users are discovering this massive roadblock only when they attempt the upgrade. It can be incredibly frustrating when your PC still performs well and meets your everyday needs. Microsoft’s strict hardware requirements for Windows 11 mean that millions of perfectly functional computers are suddenly considered incompatible. You need a reliable way to keep your current systems secure without being forced into an immediate hardware purchase.
The biggest problem people have when trying to upgrade to Windows 11 is that their computer fails the system requirements check. The official upgrade tool stops completely and displays the error seen in the image below. You are completely blocked from moving forward with the native installer.
You can use tools such as Rufus to create a bootable USB flash drive that will bypass the Windows 11 requirements such as needing to have a TPM 2.0 installed in your computer. But if you want to upgrade Windows from Windows itself, there is an easy way to do so. In this article, we will be showing you how to bypass the Windows 11 requirements when upgrading your computer from Windows 10.
If you are not sure if your computer meets the Windows 11 system requirements, you can use a tool such as the Windows 11 PC Health Check tool or something even easier such as WhyNotWin11 which is shown in the image below. As you can see, this computer doesn’t have the required amount of CPU cores and is missing the TPM (Trusted Platform Module) altogether.
Downloading and Running Flyby11
1. Download the Bypass Tool
The tool we will be using to bypass the Windows 11 requirements when upgrading your computer from Windows 10 is called Flyby11. This software can be downloaded directly from the official GitHub Assets page here. Extract the downloaded zip file into a new folder on your desktop.
2. Execute the Application
Once you extract the zip file, you will need to run the Flyby11.exe file to start the process. You may see a blue warning box appear telling you that Windows protected your PC. Click on the More info link and then click the Run anyway button.
3. Start the Upgrade Process
Flyby11 will then check your computer hardware. It tells you exactly what chances you have of successfully upgrading to Windows 11 using the tool. Click the green Start Upgrade Now button at the bottom of the window to proceed.
Configuring the Windows 11 ISO
1. Obtain the Installation Media
To perform this Windows 11 upgrade, you will need to have a Windows 11 ISO file. You can download this file straight from the Microsoft website or via the Fido script. You can do this from within the Flyby11 tool itself or download it on your own beforehand.
2. Mount the Image File
Select your downloaded ISO file within the application interface. Flyby11 will then mount the ISO image file and give you a UAC PowerShell admin prompt. You will need to click the Yes button to allow these system changes to continue.
3. Confirm Successful Mounting
Once the tool finishes its background configurations, you will see a popup box appear. It will state that the Windows 11 installation can now proceed. Click the OK button to close this prompt and move to the next phase.
Running the Windows Setup
1. Ignore the Server Setup Warning
You will then see a massive setup box that says Install Windows Server. You can completely ignore this specific text block. You will not actually be installing Windows Server on your computer. This is just a visual quirk of the bypass exploit.
2. Accept the License Agreement
Click the Next button to move past the initial server screen. You will then need to accept the official Windows license agreement to continue. Read through the terms and click the accept button.
3. Choose What to Keep
You will have the option to keep your files, settings and apps or just your personal files. There is also an option to keep nothing which forces a completely clean installation. Whatever option you choose, you should always backup your personal files before doing any type of Windows upgrade.
4. Begin the Installation
Next, you will see a summary screen detailing your exact choices. Click the Install button to begin the actual upgrade process. Your version of Windows will be upgraded to the exact same edition as it was on Windows 10. If you are running Windows 10 Home, you will be upgraded to Windows 11 Home
5. Monitor the Progress
Once again, the blue screen will say Installing Windows Server even though it is actually installing Windows 11. Setup will reboot your computer several times and also install updates throughout the process. You will then be brought to the Windows login screen where you can authenticate with your existing user account. If this specific tool fails, you can always try using Rufus to bypass the Windows 11 requirements instead.
Here is another method you can try to bypass the Windows 11 requirements when upgrading your computer from Windows 10. You can use this free tool to bypass the Windows 11 requirements and upgrade your computer.
