And yes, it does not support TPM 2.0. Luckily Windows 11 only actually requires TPM version 1.2 (even if Microsoft claims that it's not recommended): https://support.microsoft.com/en-us/windows/ways-to-install-...
(I'm not seeing any "nags" anywhere, I don't know where that would be?)
Edit: I just noticed that that page is the same that was linked from the article. Yet it still contains the block that the article claims has been removed. Did they put it back in again?
Edit 2: Or I do have TPM 2.0? It seems to think that I do:
Qq do you actually have windows 11 installed. Your original post implied you had yet TPM 1.16 is below even the TPM 1.2 version allowed.
And yes, I have Windows 11 installed
I can't tell you why it seems to think that it is a valid TPM 2.0 module, but a lot of people have reported seeing similar things, e.g. https://old.reddit.com/r/techsupport/comments/rrta2r/tpm_que...
(Btw. I'm pretty sure 16 is larger than 2. It's not saying 1.1.6. It's a version string, not a decimal number)
Edit: The name of the specification is: Trusted Platform Module Library Family “2.0”, Revision 1.16. This was released in 2014: https://trustedcomputinggroup.org/resource/tpm-library-speci...
So yes, this is TPM 2.0. And TPM 2.0 was released in a non-draft version at the time my CPU was made. And the "1.16" is the revision number of the TPM 2.0 specification that it supports.
The first draft of TPM 2.0 was 2015. The finalized version was Nov 2019. Intel 8th gen and above do have the option to upgrade to TPM 2.0 via a firmware update but as you point out those CPUs are not 10 years old.
That's one of the problems with this TPM 2.0 requirement. Tech has not moved fast in the past decade and the requirement is asking people to throw away 10 year old systems that can still easily beat today's midrange lineup.
I think what OP may be experiencing is that Windows 11 does install on older TPM 1.x hardware. It just nags to upgrade the hardware to TPM 2.0.
