On build 25905 Device security doesn't find TPM in this fully Win 11 compatible device.

Hi Pauli,

Did you try the Security processor troubleshooting?

A) Error message None, normal situation:

B) Possible error messages below can also mistakenly cause "There is no TPM available" if the yellow warning is dismissed. 🤐🤬🤷‍♂️

Seen this with Build 25905. 🤷‍♂️

Changes message from this:

to this when yellow warning in the security is dismisses. 😎🤷‍♂️

I have seen all those notifications / warnings yesterday and today on tree oldder devices. For one of those (Dell Precision T5810, not W11 supported CPU) I find TPM update, but that doesn't fix request for FW update. That attestation warning I get fixed by turnign TPM Off and On + Clear. For other two devices I'm still try to find TPM FW update, but it seem hopeless.

Only 2,5 year old laptop doesn't have any TPM errors.

Thanks for the confirmation.

I opened a separate thread on the subject.
