AMD CPU owners, particularly those with Ryzen 7 5800X3D could not install Windows 11 due to an annoying bug that does not allow them to detect TPM.
The specific glitch dubbed the "TPM attestation" bug has affected several AMD users who want to run the penultimate Windows OS.
TPM Attestation Bug Only Generates 'Ready for Use' Module
It might take some time before AMD comes up with a solution for this annoying bug.
According to a report by Neowin, some Windows users are complaining that the TPM attestation always fails every time they attempt to run Windows 11 on their PCs.
Despite the "ready for use" showing up for the TPM module, the users cannot install the software on their systems.
The news outlet notes that the game-changing bug has been affecting a myriad of Ryzen chips. In some cases, other Intel processors are affected, as well.
However, several reports claim that the most affected processor is the Ryzen 7 5800X3D which appears to be the most common case.
Some users even said that the TPM requirement has smoothly passed the test without any issues despite using a different CPU.
"After upgrading my CPU from Ryzen 5 2600 to Ryzen 7 5700X Windows Security Chip App reports 'Attestation: Not Supported' but 'Memory: Ready'. In the TPM Console it shows that the TPM Module is Ready for use." one user wrote.
Fortunately for him, switching back to the old build, specifically to Ryzen 5 2600 has solved the issue.

Is Microsoft Aware of this Ryzen Bug?
Based on a story by TechRadar, Microsoft issued a statement regarding the TPM attestation for AMD platforms. The Redmond tech firm states that as of writing, there's no known solution that can get rid of the failed TPM attestation for the error code 0x80070490 on Windows 10 and Windows 11.
With that being said, some people are still waiting for an answer from Microsoft as to when the issue will get entirely resolved.
At this point, the company is already investigating the potential cause of the bug. Neowin reports that even AMD hasn't had a clear way to eliminate this unwanted bug on Windows 11. The surefire way to avoid the problem is to buy a standalone TPM module.
As one person says, he already searched online to see if the problem persists in other users with Ryzen 7 5800X3D CPU. It turns out that some already purchased an external TPM module, but he still wondered what could be the solution if there's only one onboard for Ryzen 5800.
Another commenter on Reddit suggests that users should upgrade their CPU to a new version. With that, CMOS will be cleared, thus TPM will be disabled. Once the process is done, the owner can begin installing the new processor so he/she can turn back TPM on.
