TPM owner password/bitlocker problem RRS feed

  • Question

  • After W10 upgrade my computer doesn't recognise TPM owner password. I've cleared TPM. I activated TPM module but system doesn't ask for new one. I got a message: "Windows can keep your key secure so you don't need to remember it"; and that's all. TPM module is activated but I can't type new password. When trying to change password system asks for the old one which I didn't type.

    How can I fix this problem?

  • Hi michalzz,

    Here is a similar case for reference:
    After Update 1607 no TPM function

    Try the work around included in that link. We could join that case to help our engineer to resolve the issue.

    Best regards

  • Hi MeipoXu,

    Disabling HyperV didn't help.

  • I've made a clean install of W10 v.1607 on different computer (with different type of TPM module) and I've exactly the same problem.

  • I can only say that I never had so many problems with previous versions of Windows OS. Never.

    I've tried to set the value of the key OSManagedAuthLevel to 4 (previously = 2), in the entry HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\TPM.

    Now I can save automatically genereted TPM owner password as a file. Then I can change it. But there is another problem. Now I can change it without knowing current pasword! I can also turn off TPM module without knowing password.

    I have having this same problem since i started carrying out tests for bitlocker with TPM 1 mth ago.

    My TPM is always turned on, no matter how i clear it (in OS and in BIOS). The only way to turn the TPM off is to turn it off in the BIOS. When i want to activate it, there is no "initialise TPM" option. There is only a "Prepare the TPM" button. the laptop will then restart and when it boots into Windows, i cannot claim ownership or change password because i didnt even set the password.

    I am running on Windows 10 1511. Please help me.

    I found the solution to my question. there is another OU called TPM devices, containing all the info needed.
