    Need help on whether to clear TPM on not

    It's clear as mud. As far as I can tell, it's specific to Windows, not necessarily activated programs like MacAfee, games, etc etc etc. MS Office, I have no idea.

    Here's a lengthy doc on it: https://docs.microsoft.com/en-us/wi...initialize-and-configure-ownership-of-the-tpm

    TPM 1.2 ,is not clearing

    TPM clear doesnt affect Windows Hello

    My observations :

    Steps :

    1. Set windows Hello with fingerprint and PIN

    2. Run Clear-Tpm command

    3. system gets rebooted

    4. Windows hello finger print reader working , user can still unlock using fingerprint.





    Ques 1 : Does TPM entries for windows Hello gets recreated/restored upon reboot?



    Steps :

    1. Set windows Hello with fingerprint and PIN

    2. Run Disable-TpmAutoProvisioning -OnlyForNextRestart

    3. Run Clear-Tpm command

    4. system gets rebooted

    5. Windows hello finger print reader not working , user cannot unlock using fingerprint.

    6. Run 'Prepare TPM' from tpm.msc, TPM state changes to Ready

    7. user still cannot unlock using fingerprint.

    8. Restart Passport container service, it reloads Windows Hello hardare container

    9. User can login using fingerprint.



    Ques 2 : Does Passport container service restores TPM entries for Windows Hello?
