FlyOOBE (ex-Flyby11)

Windows Setup Assistant

Flyby11 or FlyOOBE is a free third-party software that was first known as Flyby11 and later renamed FlyOOBE. It bypasses Windows hardware requirements such as TPM and Secure Boot, which block Windows 10 users from upgrading to Windows 11. If your computer works fine on Windows 10 but doesn’t meet the official Windows 11 requirements, Flyby11 helps you upgrade easily by skipping hardware checks.

What is Flyby11?

Flyoobe is a free tool that tricks the Windows 11 installer to bypass security and hardware checks and ignore things like TPM and Secure Boot. You get an in-place upgrade that keeps all your files, apps and settings.

Windows 10 is about to end on October 14, 2025, which means computers with Windows 10 won’t receive any updates. Flyoobe helps you get those updates even after the last date without any hardware checks.

Evolution: Why Flyoobe Exists?

FlyOOBE Evolution

Flyby11 started as a simple tool to help people install Windows 11 on older computers or unsupported hardware that Microsoft considered “not good enough”. But the developer realized that installing Windows was only one problem. Once the installation was completed, people had to deal with unwanted apps and annoying setups from Microsoft.

This idea gave birth to a brand new version: Flyoobe, which basically does two things. One is to help you install on older computers like before. The second thing was to customize Windows during setup by removing junk apps and skipping unnecessary steps.

Why is it called Flyoobe?

The name gives you two ideas:

Fly: Fly as in quick and easy (fly past objects)

OOBE: Out of the box experience (the first setup process that Windows shows you). The name tells you that this tool gives you a smooth, fast set up experience where you are in control.

Flyby11 (Original): The simple original tool just helps you install Windows 11 on older computers. It is still available, but no longer gets updates.

Flyoobe (New): The upgraded version performs all the tasks that the old Flyby11 does but lets you customize Windows set up. This is the version you should use now.

Frequently Asked Questions

Flyby11 is a free tool that helps you install Windows 11 on computers that Microsoft don’t support, like those that lack TPM 2.0, Secure Boot or have an unsupported processor. It uses a Windows Server installation method, which doesn’t check your hardware requirements but installs regular Windows 11 instead of Windows Server.
Flyby11 has been renamed and turned into Flyoobe. The classic Flyby11 version exists and can be downloaded from the separate download option in Flyoobe. Flyby11 still works, but Microsoft warns that unsupported devices aren’t guaranteed they receive updates, but most of them still get the monthly security Windows update.
Yes, Flyby11/Flyoobe is completely free to download and use. But you can also donate and support the developer if you want.
Flyoobe is the advanced version of Flyby11. Flyby11 is only focused on bypassing strict hardware restrictions to install Windows 11. But Flyoobe includes new features such as customizing the Out of the Box (OOBE) that removes bloatware, tweaks settings, and debloats Windows 11.
Download the zip file from flyby11.com , extract it and run the Flyby11.exe file. You can also find the above mentioned guide to easily download and install Flyoobe. Click on “Start Upgrade Now” and select a download source for the Windows 11 ISO, and the app will automatically start downloading and installing.
Though Microsoft Defender briefly flagged Flyby11 version 1.1 as a Potentially Unwanted Application in February 2025, the later versions are no longer flagged. The tool has been thoroughly scanned by security systems and verified by industry partners and thus, shows no signs of viruses, malware or spyware when downloaded from official sources.
After downloading it from flyby11.com and starting the upgrade, choose the ISO download source and let it download automatically and mount the Windows 11 ISO. Then a Windows Server setup window appears, and you go through a standard Windows installation where you can choose to keep your files, settings and applications, etc.
Open Flyby11 and click on “Get Windows 11.” Now download the Windows 11 ISO from the Microsoft website and drag the downloaded ISO into Flyoobe, follow the instructions and run the install. Then, choose whether to keep the settings, files, and apps, and click ‘Install’. Flyby11 will start the Windows Server installation process by using the ISO you provided and bypassing all hardware checks automatically.
Flyby11 uses a feature in the Windows 11 setup that makes it behave like the Windows Server setup. Windows Server doesn’t require TPM 2.0 or certain CPU models, unlike Windows 11. Thus, the installer won’t check for these on your computer. The tool patches the ISO file and mounts it automatically, which makes the installer think that it’s installing Windows Server but the final result is the regular Windows 11 version.
Yes, most computers that are upgraded by Flyby11 receive regular updates, but Microsoft doesn’t guarantee updates for unsupported devices. According to some users, Microsoft may eventually detect the unsupported device and block updates. But you can manually download and install updates from the Microsoft Update Catalogue.

Final Words

Lastly, Flyoobe/Flyby11 is a lifeline for anyone with an older computer or hardware that still works great, but Microsoft doesn’t consider them. You can be frustrated when your completely good computer is considered “obsolete” because it doesn’t have a TPM chip or an older processor.

The Flyoobe tool does exactly what it says, which is that it runs Windows 11 on unsupported devices. And thus, a lot of users have successfully upgraded decade old systems, and a lot of them agreed that their computer works better on Windows 11.

Because it’s free and open source, it makes a big difference. But Microsoft won’t support you if something breaks, and even future updates are not guaranteed. But if you’re comfortable with some technical changes, you can have Flyby11, and it’ll solve all your problems. Just back up your important files and apps to avoid any issues.
