Microsoft Ends Windows 10 Support, Exposing 400 Million Users to Cyber Risks

Microsoft officially ended free support and security updates for Windows 10 on October 14, 2025, affecting around 400 million users worldwide who now face increased cybersecurity risks. Users are strongly encouraged to upgrade to Windows 11, which offers continued protection, or enroll in the Extended Security Updates (ESU) program for an additional year of security, though this comes with a significant cost for businesses. For those unable to upgrade due to hardware limitations, experts recommend purchasing new systems or isolating outdated devices from networks to mitigate vulnerabilities. Despite the push for Windows 11, issues with recent Windows 11 updates have emerged, including problems with local app connectivity and accessories, prompting users to await fixes. The end of Windows 10 support also presents an opportunity for small and medium businesses to reassess IT budgets and potentially invest in cloud-based sales tools for better ROI rather than just hardware upgrades. Overall, immediate action is crucial to avoid exposure to advanced cyber threats as unsupported Windows 10 devices become prime targets for hackers.
