Windows 10 2019 LTSC and Windows 10 IoT 2019 LTSC will stop receiving security updates on January 9, 2029. Windows 11 is inevitable, whether we like it or not. Once security updates stop, you’re on your own. Any new vulnerabilities found in Windows 10 after those dates might not be patched by Microsoft (although rare exceptions to this rule have happened). Still, you definitely can’t rely on it, so it’s best to upgrade to Windows 11 by October 2025. |
