Windows 11 is supposed to be a smooth and secure upgrade for Windows 10 users, but some of them are facing a strange and annoying issue that prevents them from installing the new OS. The problem affects users who have AMD Ryzen 7 5800X3D processors. AMD is staying silent on the issue while Microsoft is stalling over providing a timeline for a fix.
The issue is related to TPM, or Trusted Platform Module, a security feature that Windows 11 requires for installation. Specifically, the OS requires TPM 2.0. TPM is a chip that stores encryption keys and other sensitive data, and it can be either integrated into the processor or added as a separate module on the motherboard.
Normally, Windows 11 should detect the TPM version and status of the system and allow the installation if it meets the minimum requirements. However, some users with AMD Ryzen 7 5800X3D processors are reporting that Windows 11 fails to recognize their TPM, even though it shows as ready for use in Windows Security.
This means that Windows 11 thinks that their system is not compatible with the OS and blocks the installation. The error code that users get is 0x80070490, which indicates that TPM attestation failed.
The weird thing is that this issue seems to affect only AMD Ryzen 7 5800X3D processors, which are essentially an improved version of the Ryzen 7 5800X processors that work fine with Windows 11. Both processors have TPM version 2.0 integrated into them, so there should be no difference in terms of compatibility.
No Fix is Available and AMD is Not Saying Anything
Some users have tried to fix the issue by updating their BIOS, resetting their TPM, or changing their settings, but none of these methods worked. The only solution that seems to work is to buy an external TPM module and plug it into the motherboard, but this is an unnecessary and costly hassle for users who already have a built-in TPM in their processor.
Microsoft has acknowledged the issue in a known issue list for Windows Autopilot, a technology used by IT teams to deploy multiple Windows PCs. However, there is no update available to resolve the issue, and Microsoft has not provided any explanation or timeline for a fix.
AMD has also been silent on the issue, despite many users reaching out to them on forums and social media. AMD has not offered any guidance or support for users who are affected by this bug.
Recent AMD Ryzen Issues on Windows 11
There have been a few issues with AMD processors on Windows 11 this year, forcing the company to issue fixes. In February, the company rolled out a fix for performance problems when running the Radeon RX 6000 series GPUs and Ryzen processors when they run on Microsoft's DirectX 11.
In March, AMD was back to fix a driver timeout issue caused by a wider MPO bug on Windows 11, although the fix is limited to RX 7000 cards. In January, I reported on an issue affecting Multi-Pane Overlay (MPO) on Windows 11.
Tip of the day: Windows Update downloads can often be frustrating because they are several gigabytes in size and can slow down your internet connection. That means your device may work with reduced performance while the update is downloading. In our guide, we show you how to limit bandwidth for Windows Update downloads, so they won't bother you again.
