    I'm noticing a few entries in Event viewer>Windows logs>Application related to the TPM. It says I need a firmware update.

    Have you spoken to your reseller?

    You are a reseller. Do you know if there's an update available, or whether this is a different issue?

    Eurocom support directed me to the same thread you did. o_O:) Anyway, managed to update the firmware. No new TPM related errors in the logs. Thanks again.

    Btw. too bad that thread is locked. There are a few crucial changes to the procedure.
    Clearing the TPM can be done from the Windows Security app in settings.
    On my system I have PowerShell instead of Command Prompt, and it will not run commands on files in the current directory. E.g. to run TPM3.bat, you browse to the folder it is in and then run .\TPM3.bat

    Btw.2. Windows Hello does not use the TPM. So your fingerprint login etc. is not affected. AFAIK only Bitlocker uses the TPM, so if you don't use BitLocker, don't bother.

    CMD and powershell can exist on a system at the same time.
