Windows 10: Can I disable Intel PTT in BIOS without affecting my windows 11 installation

I want to disable Intel Platform Trust Technology PTT in my BIOS because of some dual booting-related issues. My question is if I can disable Intel PTT in BIOS without affecting anything in my current Windows 11 Home Installation?

Can’t boot with Intel PTT enabled in BIOS

Hi,
got a new Lenovo Yoga 720 with Win 10, was doing all the updates. I think the Intel Management Engine firmware update had a failure. It’s not listed in device manager and I can’t manually or automatically install a driver or see it in device manager. If I set intel PTT to disable in the BIOS, I can boot and also see TPM in device manager with code 10, but can’t update the driver. I updated the bios, downgraded, updated again. No change. I can toggle boot on and off with the PTT setting.

should I rma it? I’ve run out of ideas. Hoping you experts can help.

 

Which Do I Enable, PTT and DTMP in Bios to Upgrade to Win 11?

Hi Balahoth,

Thanks for your post in Microsoft Community.

1 - What is TPM: Trusted Platform Module (TPM 2.0) -tpm 2.0 is a microcontroller that stores key, password, and digital certificate. Independent TPM 2.0 also supports Intel® VOLARTM technology and Intel® trusted implementation technology (Intel® TXT).



The trusted platform module or TPM is a special private chip for storing the encryption key. It acts as an endpoint security for supporting it.

2 - What is PTT: Intel® Platform Trust Technology (Intel® PTT) - Intel® Platform Trust Technology (Intel® PTT) provides independent TPM 2.0 features. Intel PTT is a platform feature for credential storage, as well as key management used by Windows 8 * and Windows® 10. Intel PTT supports BitLocker * to drive encryption and supports all Microsoft requirements applicable to firmware trusted platform modules (FTPM) 2.0.



PTT provides a function of discrete TPM 2.0. Intel PTT is the credential storage and key management platform function used by Windows 11/10.



3-PTT and TPM are different technologies, but they are complementary. They are all serving equipment security services.

What is BitLocker: BitLocker (Windows 10) - Windows security | Microsoft Docs

BitLocker needs to be turned on in Windows.

Simply, BitLocker requires TPM hardware conditions and the professional and above version of Windows. So when you didn't enable TPM, BitLocker is not available.



That is, if your computer has never opened TPM after purchase, theoretically, it will not appear to automatically add BitLocker after enabling TPM.



However, since the TPM needs to be changed in the BIOS, we cannot guarantee whether you will have problems in the process of modifying the BIOS, so we recommend that you back up your personal file before performing the operation, and prepare a Windows installation media standby .

Under normal circumstances, the TPM does not cause some major changes, you can reassure after the backup file.

You can download the Windows 11 image file here. Can be used as an upgrade or to create USB installation media.

Hope it helps you.If you have any questions, you can also reply again.
