Why FlyOOBE?

Originally, Flyby11 was a simple patcher to remove the restrictions stopping you from installing Windows 11 (24H2) on unsupported hardware.
Old PC? No TPM, no Secure Boot, unsupported CPU? Flyby11 let you install Windows 11 anyway.

After helping thousands upgrade, one thing became clear:
Bypassing checks is only half the battle.
We needed a full setup solution — one that respects user choices instead of Microsoft's defaults.

FlyOOBE was the next step:

• Skip the fluff
• Remove the junk
• Take full control from first boot

Because your PC should work for you, not the other way around.
FlyOOBE keeps the original idea alive and pushes it even further.

No complicated steps.
Just run the tool (see "Releases"),
unpack if needed, and you'll be running Windows 11 on your “unsupported” machine in no time.
Think of it as sneaking through the back door without anyone noticing.

Technical Overview

FlyOOBE method:

• Uses Windows Server variant of setup → skips TPM, Secure Boot, CPU checks
• Still installs normal Windows 11
• ISO download/mount handled automatically (via Fido script)
• Matches Microsoft’s own documented workaround for upgrading unsupported devices (source)

Why Keep FlyOOBE Alive?

• Upgrade freedom – Don’t ditch a perfectly fine PC just because Microsoft says so
• Eco-friendly – Less e-waste from forced upgrades
• Save money – No need for new hardware if yours still works

⚠ Disclaimer

Flyby11/FlyOOBE uses known, currently working methods to bypass Windows 11 24H2 restrictions.
POPCNT requirement cannot be bypassed — needed for Win11 24H2.
Introduced a compatibility checker in v2.3 to warn if unsupported.

FAQ

❓ Will my unsupported device still get Windows 11 updates?

Short answer: Yes — for now. But there are no guarantees.

Microsoft says: "These devices aren't guaranteed to receive updates."
Source – Microsoft Support

Reality: Most still get monthly security updates, but:

• Likely no automatic major version upgrades
• Future updates may fail if new hardware features are required
• Microsoft could block updates anytime

Bottom line: Works today — but unsupported means you accept the risk.
