Legacy PC Guardian: Secure & Optimize Older PCs Post-Windows 10 Support

This user's concern about Windows 10 end-of-life for their functional 10-year-old PC represents a massive untapped market. Millions of users have older hardware that performs adequately but will lose security updates. A 'Legacy PC Guardian' SaaS could provide extended security and optimization. This application would offer advanced threat protection (beyond basic antivirus), exploit mitigation, system hardening, and performance optimization tools (e.g., driver management, cleanup utilities) tailored for older, unsupported Windows versions. It would act as a consumer-friendly equivalent to enterprise Extended Security Updates. Revenue would be generated through a recurring subscription model (e.g., $7-$15/month). The market includes any user unwilling or unable to upgrade hardware or operating systems, seeking to extend their PC's life securely.
