The HP TPM Configuration Utility (when used with an appropriate TPM firmware (FW) BIN file) allows for:
-
Upgrading from an older TPM 1.2 FW to a newer TPM 1.2 FW
-
Upgrading from an older TPM 2.0 to a newer TPM 2.0 FW
-
Converting from TPM 1.2 to TPM 2.0
-
Converting from TPM 2.0 to TPM 1.2
NOTE: SoftPaq 78910 has also been released. sp78910 contains the same version of the HP TPM Configuration Utility as SoftPaq 76423 (covered in this document), but has BIN files for compatibility with Windows 10 Anniversary Update (Version 1607, Build 10.0.14393, Redstone 1, RS1).

Warning!
To avoid a complete loss of data,
the drive must be fully decrypted before using the utility.
Merely suspending BitLocker is not good enough.
The utility has a built-in check for Microsoft BitLocker, HP Drive Encryption, and WinMagic SecureDoc solutions only. If BitLocker or HP Drive Encryption or SecureDoc is used, the utility will exit after advising that the disk must be decrypted first. The utility does not detect other disk encryption solutions.
Additional Notes
-
On Windows 7, TPM 1.2 must be activated in BIOS (Check TPM state in BIOS).
-
On Windows 8.x or Windows 10, the OS will automatically take ownership of TPM.
-
Windows 8.x and Windows 10 require GPT partition style when using TPM 2.0. The BIOS setting for boot mode should be set to "Legacy Support Disable and Secure Boot Enable" (recommended) or "Legacy Support Disable and Secure Boot Disable".
-
Windows 7-64, Windows 8.x, and Windows 10 will work with MBR or GPT partition style when using TPM 1.2.
