Summary

Support for Windows 10 ended on October 14, 2025, leaving users without security updates. Microsoft is cutting off Secure Boot certificates for Windows 10 in June 2026, complicating the situation for users unable to upgrade to Windows 11 due to compatibility issues or high costs. Users attempting to access tech support or Windows Update will find no assistance available, exposing them to potential vulnerabilities. While Microsoft Defender Antivirus will continue to receive updates until October 2028, the lack of overall system updates means users are at risk of unpatched security vulnerabilities. New software and hardware are increasingly favoring Windows 11, further isolating Windows 10 users. The ongoing struggle between malware creators and antivirus developers highlights the dangers of running unsupported software. Users are encouraged to consider Extended Security Updates (ESU) for continued protection against emerging threats. Key Points: • Windows 10 support ended on October 14, 2025, leaving users vulnerable. • Microsoft will cut off Secure Boot certificates for Windows 10 in June 2026. • Microsoft Defender Antivirus will receive updates until October 2028.
