Windows 10 is a personal computer operating system developed by Microsoft as part of the Windows NT family of operating systems. Officially unveiled in September 2014 following a brief demo at Build 2014, the operating system entered a public beta testing process in October 2014, leading up to and continuing through the consumer release of Windows 10 on July 29, 2015,[2] and its release to volume licensing on August 1, 2015. To encourage its adoption, Microsoft announced that during its first year of availability, Windows 10 would be made available free of charge to users of genuine copies of eligible editions of Windows 7 or Windows 8.1.
Windows 10 introduces what Microsoft described as a "universal" application architecture; expanding on Metro-style apps, these apps can be designed to run across multiple Microsoft product families with nearly identical code—including PCs, tablets, smartphones, embedded systems, and Xbox One, as well as new products such as Surface Hub and HoloLens.
