Microsoft officially ceased support for Windows 10 as of October, although users can still receive security updates for an additional year. Many computers do not meet the minimum system requirements for Windows 11, but some may still be compatible with adjustments to settings. Users can check compatibility using Microsoft's PC Health Check app and may need to enable Secure Boot and TPM 2.0 in the BIOS. UEFI should be enabled instead of legacy BIOS mode for compatibility. If compatibility issues persist, adding a TPM module may enhance compatibility for certain motherboards. Upgrading to Windows 11 is advisable for computers six years old or newer due to security vulnerabilities in unsupported systems.
