According to Neowin, it is likely that Microsoft is already aware of the existence of this bug. The list of known issues, at least for Windows Autopilot, does indeed indicate that TPM attestation for AMD processors may fail in some cases. The result is an error code “0x80070490”.
Microsoft describes the problem as follows: TPM attestation for AMD platforms with ASP TPM firmware may fail with error code 0x80070490 on Windows 10 and Windows 11 systems. There are currently no updates available to resolve this issue ».
The most important information to remember here is, unfortunately, that Microsoft does not have an immediate solution to fix this bug. AMD, on the other hand, is not much help.
According to Neowin, the firm would not have a solution to this problem either, which at this stage can only be “solved” by going through an autonomous TPM module. A far from ideal solution since it involves an additional expense. Nor can a standalone TPM module be installed on all motherboards, which further reduces the relevance of this alternative.
