Why does Windows Update say my PC can’t run Windows 11?
Often it’s because TPM is disabled in BIOS. Windows only checks if TPM is enabled — not whether your motherboard supports it.
What is TPM?
TPM stands for Trusted Platform Module. It’s a security feature required by Windows 11.
What is PTT in BIOS?
PTT (Platform Trust Technology) is Intel’s firmware-based TPM. Enabling it satisfies the Windows 11 TPM requirement.
What is fTPM?
fTPM is AMD’s firmware-based TPM solution. It performs the same function as TPM 2.0.
Is Extended Security Updates required if my PC supports Windows 11?
No. If your PC supports Windows 11 after enabling TPM/PTT/fTPM, you can upgrade instead of relying on extended updates.
