How can I update the BIOS without having to reset the Windows hello pin after the BIOS update?

I'm using an E7D43IMS (PRO B660M-A DDR4) +12thCore i5-12400.
After updating the BIOS, Windows Hello stopped and required its pin reset. I think the BIOS update caused a TPM inconsistency.
I'd like to know if this issue is resolved in the latest MSI motherboards and if it's an unavoidable limitation or specification of the E7D43IMS.
I can't stand having to reset the pin and recreate passkeys every time I update the BIOS.

BIOS Updationg that Windows Helllo required its pin reset
7D43v1N1(Beta) -> 7D43v1N (2026-03-04)
7D43v1N -> 7D43v1O (latest 2026-03-27)

Every time?
You had two BIOS updates this year (not counting betas because if you don't have specific problem you dont use those) and 2 updates last year. Come one, is ti really so hard to reset Windows PIN twice a year. Bear in mind that your board will soon stop receiveing bios updates anyway so your problem will be solved by itself!

Yes, you do this once more and you won't need to reset the pin in the future.

Thank you very much.
I understood that once I did that, this problem would be solved.
I am trying to disable FTPM, start Windows, reset the PIN, then re-enable FTPM, start Windows, and check if "PCR7 Configuration" is "Bound" or "Bindable" in msinfo32.exe.
Currently, "PCR7 Configuration" is showing as "Binding not possible".

If successfull, I would like to share this useful information with us MSI users in Japan, because many of us think that it's impossible for slightly older MSI motherboards to resolve this problem.

YMMV, but for me it's quicker and easier to just reset the Pin if necessary.

I did that, but "PCR7 Configuration" is still "Binding not possible".
Since it's impossible to create a TPM private key that won't become unusable after a BIOS update on any motherboard that can't be PCR7bound, Ive given up on this motherboard.
Thank you.
