To enable TPM/PTT on your motherboard in preparation for Windows 11, you'll want to follow these steps:
1.) Enter the BIOS.
2.) Go to "Setup".
3.) Navigate to "Advanced".
4.) Under "Trusted Computing", enable "Intel PTT Support".
5.) Save these settings with "Save and Exit".
This will enable TPM on the system. However, you will still need to enable Safe Boot to ensure a full installation of Windows 11 is successful.
To enable Safe Boot:
1.) Enter the BIOS.
2.) Go to "Setup".
3.) Navigate to "Boot".
4.) Navigate to "CSM Configuration" and disable it.
5.) Navigate from "Boot" to "Security".
6.) From "Security" head to "Secure Boot" and enable it.
7.) Save these settings with "Save and Exit".
You will then be able to use WIN + R in Windows, run tpm.msc, and be able to see if your TPM device is ready. If successful, you will see, "The TPM is ready for use" and means your TPM is ready for Windows 11. Otherwise, you will see the message, "Compatible TPM cannot be found".
Your motherboard will need to support Secure Boot in order to support TPM. You can check your compatibility HERE.
