    Bitlocker and Trusted Platform Module problems

    We appreciate the screenshot you sent.

    This issue usually occurs because the Trusted Platform Module (TPM)
    uses the manufacturer driver and not the Windows built-in Trusted Platform Module driver.

    To resolve this, you can manually uninstall and reinstall Trusted Platform Module. To do so, see the steps below:

    • Open Device Manager on the device on which you are experiencing the issue
    • Uninstall the Trusted Platform Module driver.

    Give us an update after following the troubleshooting steps provided.

    TPM Trusted Platform Module Issue

    After updating to windows 10 version 1803 this comes up after I log in. A configuration change was requested to clean this computers TPM( trusted platform module). Warning clearing erases information started on the TPM. You will lose all created keys and access data encryption by these keys.
    Press F12 to clear the TPM
    Press ESC to reject and continue.
    I have done this numerous times on every restart.
    I go into windows defender to view security dashboard to view device settings to security processor to ignore the request for the TPM and it is fixed but again when I restart to asked the same question over and over.

    Microsoft Guidance for Vulnerability in Trusted Platform Module (TPM)

    Verify Trusted Platform Module (TPM) Chip on Windows PC


    Something I came across not long ago, is Firmware-based Trusted Platform Modules (fTPM). Whereas before in order to take advantage of a TPM you needed to have a physical TPM chip soldered to the motherboard, that seems to have changed at some point. You can now have either a Discrete TPM (Physical chip) or Firmware-based TPM.

    As per THIS article, fTPM is acknowledged by the Trusted Computing Group (TCG) as a perfectly valid form of TPM and seems to perform much the same functions as a physical TPM. For Intel, their fTPM is called Intel Platform Trust Technology (PTT). I don't know what chips/motherboards/BIOS support PTT, however due to it being Firmware based (as the name suggests) and not requiring a separate physical chip, it means for some devices it's possible to retrospectively add a TPM to devices that didn't have one before.

    Looking through the Intel NUC list, it's not just 6th gen Skylake NUC's that it's supported on, but also 5th gen Broadwell NUC's and 4th gen Haswell NUC's too. So if you have a NUC and you have the latest BIOS, then the chances are you have a TPM 2.0 module even if you didn't think you did. You just need to enable 'Intel Platform Trust Technology' in BIOS. As previously mentioned, I don't know what other manufacturers support/will support fTPM too.


    The Intel Platform Trust Technology (PTT) setting in Intel VisualBIOS:

    With Intel PTT on in BIOS, Device Manager and tpm.msc show a TPM 2.0 module installed.
