Windows 10 users will lose official support from Microsoft on October 14, 2025. The Extended Security Updates (ESU) program will be available to consumers for the first time, allowing users of older systems to receive critical security updates for an additional year. The ESU program is a temporary solution and not intended as a long-term fix. Consumers will pay a fee for a single year of security updates, while businesses will face escalating costs that double each year. If a business joins in the second year, it must also pay for the first year's updates, as the ESUs are cumulative. The ESU program provides a way to maintain security for Windows 10 users before transitioning to Windows 11.
