    Should I disable my TPM before upgrading from Win7 to Win10?

    So I'm finally making the plunge to Win10 now that Win7 is no longer officially supported.

    I wanted to make sure I don't lock myself out and upgrade properly.

    Should I disable my TPM before starting the Win10 upgrade and then just re-enable it once I get the upgrade complete?

    Or does the Win10 recognize it and setup properly while it's still "Owned/Enabled" from my Win7 install?

    The TPM is 1.2 and that's all my current mobo supports, so I'll just have to stick that that for now and worry about TPM 2.0 later down the road when I do a full system overhaul in a couple years.

    Also, I have my SSDs setup with FDE through BIOS and don't want/need Windows 10 encryption slowing anything down.

    How can I make sure that Bitlocker isn't enabled on top of my FDE, but my TPM is still enabled?

    Windows 10 starting build 1509 Supports both 1.2/2.0 versions of TPM , but weather you should turn it off or would it upgrade smoothly from a Windows 7 installation , your request is so specific and narrow that I doubt anyone can offer you but speculations . Like mine would be if your TPM is hardware and part of SSD/HDD/Bios then I assume late windows installations can deal with it . But don't count me responsible if not :)

    But at least I know Bitlocker upgrades to off by default if wasn't enabled on older windows .

    There is no need to turn off the TPM to upgrade Windows.
