1. Microsoft ends mainstream Windows 10 support on October 14, 2025, stopping security updates and technical assistance.
1. However, free Extended Security Updates (ESU) are offered until October 2026 for users opting into the Windows Backup app.
1. Alternatively, users can extend ESU until 2026 by redeeming 1,000 Microsoft Rewards points or paying $30.
1. The major catch: Free critical security patches beyond 2025 require action - using Windows Backup or Rewards points.
1. ESU only provides essential security fixes; no new features, design changes, or non-security updates are included.
1. Microsoft 365 apps and Defender antivirus will continue receiving security updates separately until October 14, 2028.
1. This extension is crucial to protect millions of devices unable to upgrade to Windows 11 from vulnerabilities.
1. Microsoft strongly recommends upgrading eligible devices to Windows 11 for ongoing, comprehensive support.
1. The ESU program offers a vital, albeit limited, safety net for users and organizations needing extra transition time.
