    I am Win10/Pro, 21H2.

    Why does the TPM app (Settings>Windows Security>Device Security>Security processor, click on the link for Security processor details) sometimes say under the Status heading “Attestation: Not ready” and a minute later say “Attestation: Ready”? See attachments.

    The machine had been running for a few hours, so it’s not like it just powered up.
