Last week Windows Defender Security Center alerted me to a firmware update of the security processor (TPM).

Clicking on Learn more took me to a support website of Microsoft containing a step by step guide and some information about the firmware update (see here). According to the guide I had to download the firmware update from the device manufacturers support website.

Important: As pointed out in the setup wizard of the downloaded .exe it just extracts some files to C:\SWSETUP\SOFTPAQ_NUMBER (in my case: C:\SWSETUP\SP82133) and does not install the firmware update.

Next the following steps have to be performed.

  1. Install latest Windows updates
  2. Enable TPM in BIOS, if not yet enabled

    Hint: In my case I first had to set security level (as guest user) of TPM in BIOS (Security > Set Security Level) to write. After that I was able to enable TPM in BIOS with my user account.

  3. Go to the folder containing the firmware update (C:\SWSETUP\SOFTPAQ_NUMBER)
  4. Open Readme.html
    • Make sure that all requirements listed in section Requirements are met
    • Read section Important Notes
  5. Start executable according manual
  6. If you get asked to provide the Owner Password or a Owner Password Backup File and you don’t know it or don’t have it, follow the instructions under Windows 10 ® Version 1607 and later to clear the TPM
    WARNING: Clearing the TPM resets it to factory defaults. You will lose all created keys and data protected by those keys.
