Note 2: If BitLocker is enabled on your system, please make sure you suspend BitLocker encryption before updating TPM on a BitLocker enabled system.
Note 3: The TPM must be ON and Enabled in BIOS Setup, and the TPM must not be owned. If the TPM is owned, go to BIOS Setup and clear the TPM before proceeding. You may need to run TPM.msc to re-initial the TPM under Windows OS.
Note 4: When the TPM ownership is cleared, some operating system will automatically take ownership of the TPM on the next boot (TPM AutoProvisioning). This feature will need to be disabled in the OS to proceed with the update.
