Microsoft's latest operating system, Windows 11, has been making waves in the tech world since its release. With its sleek new design, improved performance, and enhanced security features, many users are eager to upgrade to the new OS. However, before making the switch, it's essential to ensure that your device is compatible with Windows 11.

| | Likely Cause | Fix | |-------------------|------------------|---------| | TPM 2.0 not found | TPM disabled in BIOS | Reboot → BIOS → Enable Intel PTT (for Intel) or AMD fTPM (for AMD) | | Secure Boot off | CSM/Legacy mode enabled | Switch BIOS to UEFI mode, enable Secure Boot | | CPU not supported | Old processor (e.g., Intel 6th-gen) | Option 1: Stay on Windows 10 (supported until Oct 2025).
