Microsoft will cease support for Windows 10 on October 14, 2025, affecting an estimated 200 to 400 million devices that will no longer receive updates or patches, exposing them to security vulnerabilities. Transitioning to Windows 11 requires modern hardware specifications, which many older devices lack. Users must decide between investing in new hardware, opting for extended security updates, or switching to alternative operating systems like Linux. The Document Foundation advocates for Linux and LibreOffice as viable alternatives, emphasizing their ability to run on older hardware and providing robust security updates. Linux offers users greater control and transparency, addressing privacy concerns associated with proprietary systems. LibreOffice supports open document formats, ensuring long-term accessibility without vendor constraints. The end of Windows 10 support may prompt significant shifts in the tech industry, encouraging a move towards systems that prioritize sustainability and user rights.
