Microsoft has recently removed the official TPM and CPU bypass guide for installing Windows 11 on unsupported PCs. While the Registry tweak previously shared by the company may still work fine, it's weird to see it being removed from the official support page.
Now, the company has flagged a third-party Windows 11 system requirements bypass tool called Flyby11 as a potential malware. This tool has been recently updated, and it now has incorporated the Registry tweak that Microsoft previously shared on the official support page.
In the update notes, the developer of Flyby11 states that Windows Defender flags the bypass tool as "PUA:Win32/Patcher," and advises users to ignore the alert if they want to use the tool. The developer added that they would get in touch with Microsoft to verify the flag.
For those wondering, per Microsoft Security Intelligence, PUA:Win32/Patcher classified software is a potential malware. These can "affect the quality of your computing experience."
While this TPM bypass tool was previously marked safe by Windows Defender, there's no guarantee that it's now putting out a false positive alert. It's third-party software, after all, so if you were to use it, testing the tool on a VM or a secondary PC (Beelink Mini S12 Pro curr. $159 on Amazon) would be a good idea.
Another thing that's worth noting is that Flyby11 isn't the only Windows 11 TPM bypass option available. You can get through the system requirements check with Rufus, and for low-end PCs, there's Tiny11.
