Windows 10 was launched in July 2015. It was supposed to be the last major operating system (OS) upgrade, but Microsoft released Windows 11 in October 2021, and now Windows 10 has reached end of life, which means it will no longer be updated. Consumers who register for extended support and back up their PCs in the Microsoft cloud will be able to get free security updates until October 2026. Corporate PCs and devices connected to Active Directory will only receive Windows 10 security updates if they are covered by an Extended Security Updates (ESU) subscription.
