TPM 2.0 (Trusted Platform Module 2.0) is a security chip or firmware component that stores cryptographic keys and helps ensure your PC boots with trusted hardware and software. Microsoft uses it in Windows 11 for features like device encryption and secure sign‑in, forming part of a stricter, hardware-based security baseline. TPM 2.0 is a formal minimum requirement for installing or upgrading to Windows 11.
What if my PC doesn't support TPM?
Many systems show "no TPM" in Windows simply because the firmware TPM is disabled. Check your BIOS for a TPM setting (e.g. Intel PTT (Platform Trust Technology), AMD fTPM, "Security Chip", "TPM Device") and enable it, or consult a PC specialist. Furthermore, some motherboards are equipped with a dedicated slot that accepts a TPM 2.0 module. Consult a PC specialist for details.
