Windows 11 upgrade failed as it says "The PC must support TPM 2.0"

TPM 2.0 is a critical security requirement for Windows 11. It offers better protection against modern threats. If your PC doesn't support it, you can buy a new TPM 2.0 chip and insert it into the motherboard to fix the pc must support TPM 2.0 error.

Step 1: Check if Your Motherboard Supports a TPM Module

1. Open Device Manager (press Win + X and select it).
2. Look under Security Devices for "Trusted Platform Module" (if missing, your PC may need an add-on chip).
3. Check your motherboard manual (or manufacturer’s website) to confirm if it has a TPM header (usually labeled TPM, TPM 2.0, or SPI_TPM).

Step 2: Buy a Compatible TPM 2.0 Module 

Purchase a TPM 2.0 module that matches your motherboard brand:

• ASUS    ASUS TPM-M R2.0
• Gigabyte    GC-TPM2.0_S
• MSI    MSI TPM 2.0 Module
• ASRock    ASRock SPI TPM

Step 3: Install the TPM Module

1. Power off your PC and unplug it.
2. Open the case and locate the TPM header (refer to your motherboard manual).
3. Insert the TPM module carefully (align the pins correctly).
4. Secure it with a screw (if included).
5. Close the case and power on the PC.

Installing a TPM 2.0 module is possible if your motherboard supports it. Otherwise, consider enabling firmware TPM or upgrading the unsupported PC from Windows 10 to Windows 11 without TPM 2.0.
