Microsoft's Extended Security Updates (ESU) program for Windows 10 allows users to link consumer ESU licenses to personal Microsoft accounts, enabling use on up to 10 devices. Enrollment is simplified, requiring devices to run the latest Windows 10 update (version 22H2) and have administrator privileges. Users can enroll additional devices without separate enrollment. The ESU program extends security updates until October 13, 2026. For commercial devices, a fee is required per device for updates, with renewal options available for up to three years at increasing costs.
