Why does my Aspire TC-780 device security say 'Attestation not supported' if I have TPM 2.0?

Yes my Aspire TC-780 in Device security says under security processor/ security processor details says. Specifications/ manufacturer Intel (INTC) Manufacture 11.8.50.3399/ specification version 2.0 PPI specification vertion 1.3 / TPM specification sub-version 1.16 (9/21/2016) PC client spec version 1.00

    What are you trying to use the TPM for? That might be a message your security software is generating. Almost all the hits I see on that message are for Windows 11, and your computer doesn't support Windows 11.

    I did a clean Install and before I did the clean install I did clear the TPM and nothing happened I had the same issue. It's strange I know my computer very well and It showed that Attestation was supported and my TPM was showing it was there and working how is that possible? That it's missing now? It did show it was working about 6 months a go Aspire TC-780 in Device security says under security processor TPM 2.0 was there and working at that time. My real question is my Acer is it safe? with out the support "security processor"

    I would like to have the issue fixed with the TPM but I do know my Acer will not update to Windows 11 even when the TPM 2.0 was working? It's just strange that its saying the TPM 2.0 it's not supported now and missing under security processor details.

    Unless you are running security software than uses TPM, typically found in large commercial environments, you aren't using the TPM for anything. Windows 11 uses it for some of their security features but Windows 10 doesn't. No need to worry if you are running any antivirus, like the Windows Defender bundled with the OS, and not visiting risky sites.
