If you are trying to upgrade or optimize your system for modern security standards, you have probably come across the term “TPM” or “Trusted Platform Module”. With the release of Windows 11, “TPM 2.0” has become a strict requirement, leaving many users wondering how to move from “TPM 1.2” to the newer version.
In this guide, I’ll walk you through everything in detail so you can confidently upgrade your TPM version without any unnecessary confusion.
Let’s start!
How to Change TPM 1.2 to 2.0 in Windows 11?
To change “TPM 1.2” to “TPM 2.0” in Windows 11, access your system’s BIOS or UEFI firmware settings, locate the TPM or security chip configuration, and switch it to “Firmware TPM” or “TPM 2.0 mode” if supported. Save changes and restart your PC. Note that not all systems support this upgrade, especially older hardware.
Before jumping into the steps, it is important to understand one key thing. “TPM 1.2” and “TPM 2.0” are not always separate physical chips. In many modern systems, TPM is implemented as firmware-based TPM, often referred to as “fTPM” for AMD or “PTT” for Intel. This means your device might already support TPM 2.0, but it is either disabled or set to an older mode.
However, if your motherboard or processor is too old, upgrading TPM may not be possible without hardware replacement. So think of this process less like installing something new and more like unlocking a feature that may already exist.
Now, let’s walk through it step by step.
Step 1: Check Your Current TPM Version
Before making any changes, you need to confirm whether your system is actually using “TPM 1.2” or already supports “TPM 2.0”.
Press the Windows key and type “tpm.msc”, then hit Enter. This opens the “Trusted Platform Module Management” window. Look for the section labeled “Specification Version”. If it shows “1.2”, then you are running the older version.
This step matters because sometimes users assume they need an upgrade when TPM 2.0 is already available but just not enabled properly.
Step 2: Verify Hardware Compatibility
Now comes a reality check. Not every system can switch to TPM 2.0.
Open “Device Manager” or check your system specifications online. Look up your processor model and motherboard. Systems with newer Intel processors typically support “Intel Platform Trust Technology”, while AMD systems may support “AMD fTPM”.
If your system supports firmware TPM, you are in luck. If not, you may need a dedicated TPM 2.0 module installed on your motherboard, provided it has the required header.
Step 3: Back Up Important Data
This step is often skipped, but it is extremely important.
Changing TPM settings can affect “BitLocker encryption” or other security features tied to your current TPM configuration. If anything goes wrong, you could lose access to encrypted data.
Make sure you back up all critical files to an external drive or cloud storage. If you are using BitLocker, consider temporarily suspending it before proceeding.
Step 4: Enter BIOS or UEFI Settings
Restart your computer and enter the “BIOS” or “UEFI firmware settings”. This is usually done by pressing a key like F2, F10, Delete, or Esc during startup.
Once inside, do not rush. The interface may look different depending on your motherboard manufacturer, but the options you are looking for are generally under sections like “Advanced”, “Security”, or “Trusted Computing”.
Step 5: Locate TPM Configuration
Now you need to find the TPM-related settings.
Look for terms such as “TPM Device”, “Security Device Support”, “PTT”, “fTPM”, or “Trusted Platform Module”. On Intel systems, you will likely see “Intel PTT”, while AMD systems will show “AMD fTPM”.
If TPM is disabled, enable it. If there is an option to switch between versions, select “TPM 2.0” or a setting that corresponds to firmware TPM.
Step 6: Enable Firmware TPM Mode
This is the core step where the actual change happens.
If your system currently uses a discrete TPM set to version 1.2, you may have the option to switch to “Firmware TPM”, which typically supports version 2.0. Select this option carefully.
On some systems, you may see choices like “Discrete TPM” and “Firmware TPM”. Choose firmware-based TPM to access version 2.0 capabilities.
Step 7: Save Changes and Restart
After making the necessary adjustments, save your settings and exit the BIOS.
Your computer will restart. At this point, the system should initialize TPM 2.0. This process usually happens automatically, but in some cases, you may see prompts related to TPM reset or initialization.
Follow on-screen instructions if prompted.
Step 8: Confirm TPM 2.0 Activation
Once you are back in Windows, repeat the earlier step.
Open “tpm.msc” again and check the “Specification Version”. If everything went correctly, it should now display “2.0”.
If it still shows 1.2 or does not appear at all, revisit your BIOS settings and ensure the correct options were selected.
Step 9: Re-enable Security Features
If you disabled “BitLocker” or other security tools earlier, now is the time to turn them back on.
This ensures your system remains protected while benefiting from the improved capabilities of TPM 2.0, such as enhanced encryption standards and better compatibility with Windows 11 features.
FAQs
What is the difference between “TPM 1.2” and “TPM 2.0”?
The main difference lies in security algorithms and flexibility. “TPM 2.0” supports newer cryptographic standards and is required for modern operating systems like Windows 11, while “TPM 1.2” uses older, more limited encryption methods.
Can I upgrade TPM 1.2 to 2.0 on any computer?
No. The upgrade depends on your hardware. Many newer systems support firmware-based TPM 2.0, but older devices may not support it at all.
Do I need to buy a new TPM chip?
Not always. In many cases, you can enable “fTPM” or “PTT” in BIOS without purchasing additional hardware. Only older systems may require a physical TPM 2.0 module.
Will changing TPM erase my data?
It can affect encrypted data, especially if you are using “BitLocker”. That is why backing up your files before making changes is strongly recommended.
Why does Windows 11 require TPM 2.0?
Windows 11 uses TPM 2.0 to enhance system security through features like secure boot, device encryption, and protection against firmware attacks.
What if the TPM option is missing in the BIOS?
If you cannot find TPM settings, your system may not support it, or it might be hidden under a different name. Updating your BIOS firmware can sometimes reveal the option.
