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

If the Windows 11 upgrade fails with the message "The PC must support TPM 2.0," and you attempt to bypass or ignore this requirement, TPM 2.0 provides hardware-based security features like secure boot, device encryption, and protection against firmware attacks. Bypassing it weakens these protections, leaving your system more vulnerable to malware and unauthorized access.

Windows 11 is optimized to work with TPM 2.0. Without it, some features may not function correctly, leading to system crashes, instability, or unexpected behavior. Certain hardware drivers or security-sensitive applications may require TPM 2.0 and could malfunction or refuse to run on systems without it. Future Windows updates and security patches may rely on TPM 2.0 features. Running Windows 11 without TPM could mean missing out on critical updates or facing compatibility issues down the line.

Microsoft may restrict or disable updates on unsupported configurations, which could leave your system vulnerable or outdated. So that Windows 11 upgrade failed as it says "The PC must support TPM 2.0". Bypassing hardware requirements might violate Microsoft's licensing terms, potentially affecting support options and warranty.
