He has done it again. The developer of several useful open source tools, Belim, has changed the name of another of his applications. The useful open source Windows-11-Upgrader Flyby11 is now known as FlyOobe.
The program itself makes it easier to upgrade Windows 10 systems to Windows 11, especially if the computer does not meet major system requirements of Windows 11. While you can bypass most requirements manually, using FlyOobe simplifies the process significantly as it requires just a few clicks to start the upgrade.
The new name reflects the nature of the program better, according to the developer. Thankfully, that is not all that is new. The latest version includes a few changes already, like improved upgrade logic or automatic compatibility checks before selection of the ISO.
Here is the full changelog:
Improved upgrade logic for bypassing Windows 11 requirements
Automatic compatibility checks before ISO selection
New hybrid UI with dark main window and a light sidebar. Drop a comment: full dark, back to light, or keep the hybrid look?
More intelligent handling of setups with and without Internet
Hundreds of fixes, cleanups, and refinements under the hood
Clippy was killed. Again.
The old FAQ was removed (a new one will appear in the repo soon)
Localizations are currently offline because they no longer fit with the core features. I still need to figure out how to move forward with this
More interesting than that is what is coming next. The developer is working in integrating ISO preparations and bypass patching directly from ISO images into the application.
Means, it is future proofing the program to make sure that it continues to work, even when Microsoft decides to disable the existing bypass options.
With Windows 10 going out of support in two months, it will be interesting to see if the downloads of tools like this will explode. While users may be able to sign up for extended security updates, this is delaying the death by just a year. Enough time for some, but there will be millions of perfectly working Windows 10 PCs in October 2026 that could be used for years or even decades, if their owners would get some help migrating to Windows 11 or Linux, or another option.
I honestly don’t know; the more I read about the tools and techniques for upgrading to Windows 11, the less I trust the various scripts and tools provided. Not so sure if this is possible: “Means, it is future proofing the program to make sure that it continues to work, even when Microsoft decides to disable the existing bypass options.” Anyway, thanks for keeping up with updates and offering all the help you do. I’ve seen a few others sites recommending Flyby11–ZDNet has a good tutorial with screenshots.
As I understand it, users can bypass the Windows 11 system requirements to upgrade from Win 10, but what they won’t qualify for are security updates. Without those you could be stuck up a creek without a paddle.
Security updates worked fine so far on test machines. The only roadblocks you will run into is when feature updates get released, as these won’t be offered via Windows Update and may not install without circumventing the requirement checks.
