Windows 10 is from today an insecure operating system. One that is installed on 4 out of every 10 computers in the world

The end of official support for Windows 10 marks a critical shift in the cybersecurity landscape, leaving a significant portion of the world's computers vulnerable to cyber threats. As of today, this operating system will no longer receive security updates from Microsoft, exposing its users to potential exploits and vulnerabilities. This change affects a considerable number of users, highlighting the importance of timely software updates. Windows 10 remains a widely used operating system, with approximately 40.5% of Windows PCs globally still running on it as of September 2025, according to Statcounter GlobalStats. While Windows 11 has surpassed it in market share, the margin is slim. This means that four out of every ten Windows-based computers worldwide are now using an insecure operating system, with older versions like Windows 7 (9.61%) presenting even greater risks. The impact of unsupported software extends beyond individual users, affecting businesses and critical infrastructure that rely on these systems. Remembering incidents like the WannaCry ransomware attack in 2017, which exploited vulnerabilities in older Windows versions, underscores the dangers of running outdated software. Organizations and individuals need to prioritize upgrading to supported operating systems to protect against potential cyberattacks and data breaches. This situation emphasizes the need for proactive cybersecurity measures and the importance of staying current with software updates. The move also highlights the ongoing challenges of maintaining a secure digital environment, and the necessity for both individuals and organizations to take responsibility for their digital security.
