Windows Update and PC Health Check Disagree about Windows 11

[jameswesthead]

Earlier today I disabled fTPM in my X570 Aorus Master EFI and installed a TPM hardware module on the vacant header. I then enabled Secure Boot.
In Windows 11 (I have a dual boot of 10 and 11 - windows 11 is an insider installation) there are no problems using it, and PC Health Check shows all boxes ticked. (see attachment: PCHEalthCheck)
In Windows 10, however, PC Health Check again shows all boxes ticked (PC is good for Windows 11), BUT in Windows Update, there is a warning saying that the PC is NOT suitable for Windows 11(See attachment Windows Update). The TPM Management Console shows that the new TPM module is fine. (see attachment: TPM management Console).
Has anyone any idea of what is going on regarding these discrepancies. Windows Update is clearly incorrect, since I can run Windows11.

The problem has resolved itself. A few minutes ago Windows 10 Update no longer had the spurious message.
Perhaps Update only actually check the Windows 11 "readiness" status occasionally, rather than on entry.
