The developer of a tool that lets your computer beat Windows 11’s restrictions to install the operating system has released a new version after Microsoft’s security software blocked the program. Flyby11 uses the installation setup designed for Windows Server, which businesses use to run Windows across a network of computers.

Windows Server doesn’t check whether a computer has the correct technical specifications for running Windows 11. Flyby11 exploits this loophole to install the system on machines even if they lack Secure Boot or the TPM 2.0 processor.

On 1 February, Flyby’s developer Belim said that Windows Defender was flagging version 1.1 of the program as a PUA (Potentially Unwanted Application).

PUAs aren’t necessarily malware but can harm your computer by making it run slower, showing intrusive adverts or installing extra software without your permission.

Within a few days Defender had stopped blocking Flyby11 and reclassified it as a ‘HackTool’. These are tools that can modify or bypass system restrictions, licensing protections or security settings.

Belim responded to Microsoft’s actions by releasing several new versions of Flyby, which he says don’t
get flagged at all by Defender.

Belim, who’s based in Germany, has now released version 1.6 – though he works quickly so there may be an even newer version by the time you read this.
