Windows 10 Extended Security Updates (ESU) - Summary
Windows 10 reached end of support on October 14, 2025. Devices can continue to operate, but they no longer receive standard security updates unless they are enrolled in the Extended Security Updates (ESU) program. ESU provides Critical and Important security updates, as classified by the Microsoft Security Response Center (MSRC), but does not include new features, general bug fixes, design changes or normal technical support.
