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

TPM (Trusted Platform Module) 2.0 is a security chip (either hardware-based or firmware-based) that provides cryptographic functions to enhance system security. It stores encryption keys, passwords, and certificates securely, protecting against malware and unauthorized access.

Why is TPM 2.0 Required for Windows 11? Microsoft made TPM 2.0 mandatory for Windows 11 to ensure stronger security against modern threats like ransomware, firmware attacks, and identity theft.  TPM 2.0 enables features like:

• Secure Boot (prevents malicious software from loading during startup).
• BitLocker Encryption (protects data if a device is lost/stolen).
• Windows Hello (secure biometric authentication).
• Prevents Firmware Attacks – Protects against low-level exploits that bypass traditional antivirus.
• Future-Proofing – Ensures compatibility with upcoming security features.

Unfortunately, some older PCs (pre-2016) may lack TPM 2.0 but have TPM 1.2 (not sufficient for Win 11). You can enable TPM in BIOS/UEFI (look for settings like "PTT" for Intel or "fTPM" for AMD).

If your PC does not come with TPM 2.0 chip, then you can use dedicated tool to skip "The PC must support TPM 2.0" error during Windows 10 to Windows 11 upgrade.
