    TPM not needed for BitLocker?

    I have some Win 8 laptops which all have BitLocker running.

    On some laptops with TPMs, I chose the pin# method.
    However, one laptop without TPM, still supports BitLocker except I use long passwords instead.
    But no "USB Key" needed like the one for Win 7 laptop without TPM.

    Does Win 8 inherently support BitLocker with/without TPM?

    Does TPM somehow make only using PIN# more secure?

    Thanks.

    TPM is meant to prevent the disk being removed and installed elsewhere, whilst allowing you to use the PC just by logging in.
    Password is used instead of TPM.
    USB is used instead of TPM.

    I see thank you.
    But then Win 7 I guess can't do this? My Win 7 laptop can't do BitLocker without USB.

    Does TPM accelerate bitlocker in anyways? Like Intel i5 chips and above do for AES encryption?

    Thanks gain!

    No, TPM is just a source of encryption data.

    cheers, Paul
