TPM - Am I doing something wrong? Enabled five times now - keeps turning itself off

[FW4TeePee]

I have had to enable TPM Operation five times in the past month as, on logging on to Windows, I am greeted by challenges to reset passwords. Shouldn’t it remain enabled once set? Or am I doing something wrong? Perhaps I have to set it to something else?

• Windows 11 (26220.8474)

• New (recently replaced) mainboard

It’s non-obvious. I’ve written up a bit about this on this very forum here and here.

@DHowett

“No operation” means “do not change anything about the TPM when I exit this page”. It does not mean “the TPM is not operational.”

Thanks for the links @DHowett but …hmm.

My experience is, as I noted, that Windows has a problem with TPM and asks me to reestablish authority. The issue, according to the Windows error message, is an incorrectly configured TPM (Windows recognises TPM’s presence but finds its configuration unacceptable).

So, I head back into the Bios setup, “Enable” TPM Operation, and Windows is happy again … for a while anyway.

How do I resolve this?
