When was Windows 10 released?

Windows 10 was officially released on July 29, 2015. This version of Windows marked a significant shift for Microsoft as it aimed to unify the user experience across multiple devices—PCs, tablets, and smartphones. Windows 10 introduced several new features such as the Start Menu, Cortana (a digital assistant), and the Edge browser, alongside regular updates to ensure that users had the latest enhancements and security improvements.

The other years listed do not correspond to the release of Windows 10. The year 2012 marked the release of Windows 8, which was a complete redesign of the Windows interface. The years 2018 and 2020 reflect later updates and versions, such as the Windows 10 updates that occurred during those times, rather than the original release of the operating system itself. Thus, 2015 is recognized as the pivotal year for the launch of this popular operating system.
