    You are missing the PowerShell version...
    get-tpm will show a whole bunch of information about your computer's TPM situation but if you are looking specifically to see if the chip is present then use this:
    get-tpm | select -ExpandProperty tpmpresent

    Let me be clear here: I do not want people to think Bitlocker is worthless. Bitlocker works well for what it's designed to do: Safekeep what sound-minded people would keep on a personal computer. Its creation was never intended to be a concrete safety "vault."

    Using hardware + Bitlocker is the route one should go when using Bitlocker outside the range of just storing their porn folder or "warez." Hardware cryptography + encryption is a great combination. For those who have a motherboard lacking a TPM header, a Yubikey 4 can be purchased for $40 and work better because it's removable and not just a perepherial added to the motherboard.

    Even using Bitlocker in conjunction with 7zip's AES-512 to protect a collection of files works well, and again, it's free.

    I personally use a VeraCrypt container on a Bitlocked drive that is Yubikey unlocked for safe keeping moderate personal records and documents. It's an excellent combination. VeraCrypt alone surpasses 99% of paid encryption software. Features like TRULY hidden containers work exceptionally well: You will never find them, a format removes the encrypted container holding encrypted information, so the data is unrecoverable (by the great majority of software the public has access to). Even when I have done a low-level format of a Bitlocked partition with an encrypted VeraCrypt container, then used the means I have to restore the encrypted files, 99% of them were corrupt upon restoration. Using Bitlocker alone, though? I can restore a partition you format over 200+ times. write zeros to, 2-3 pass "wipers," etc. with very little data corruption.

    If you want something hardware exclusive that's cheaper, take at hardware encrypted flash drives. You can find AES-256+ units, or FIPS 140-2 validated USB 3.0 flash drives that are not that expensive. From there you get all the way up into what I use for my home office (due to the work I do).

    Sidenote: Always use a nice, long PIN to secure anything software locked. They're always more secure, no matter how obnoxious your password was going to be.

    Hello!
    I'm pretty new in the encryption I work with sensitive data and need to protect.

    I see that you know a lot and have a few questions.
    Where is PTT located (on the motherboard or into CPU)?
    *
    2. Is PTT equivalent secured with TPM 2.0?
    I can put TPM 2.0 chip on the motherboard but also support PTT must I need to buy TPM and why?
    *
    3. How can I use Smart Card yubikey 5 NFC to unlock my OS drive?
    I try but see: a certificate suitable for BitLocker cannot be found on your smart card
    *
    4. I see that you say (I can recover BitLocker drive after low-level format). Is this true?

    Please help me because I can't find the right information into the web.

    Thank you

    So guys, after I updated my computer bios (for NVidia REBAR support), the Intel TPM Provisioning Service is suddenly hounding the firewall for internet access, its almost like malware behaviour, and yes it is the legitimate service. The bios update triggered it, specifically I discovered full UEFI boot has started this behaviour instead of UEFI with CSM.

    I have verified in the security applet there is no security hardware enabled, isnt in device manager either, its disabled in bios, and finally confirmed with get-tpm.

    Given all this confirmation the hardware is not present for windows, is it safe for me to disable the service? Or is there another known way to stop the service trying to access the internet?

    TpmPresent : False
    TpmReady : False

    You should be able to safely stop and disable the service since you do not have a TPM available.

    Thank you, I have confirmed the internet requests have stopped, I was worried it may affect other cpu features or other ill effects but all seems ok at the moment. :)

    Hiyya Shawn My Ivy Bridge build is not showing a TPM in the Device Manager and I am not sure of how to check in the BIOS whether there is such a thing as TPM that can be turned on somehow.
    The board is an Asus P8Z77-V by the by and my second major build.

    Hello John,

    The specs at ASUS below shows the P8Z77V motherboard does have a TPM connector to add one, but it doesn't look like it has one included.
