Windows 10 (codenamed Threshold)
is an upcoming PC operating system developed by Microsoft as part of the Windows NT family of operating systems. Initially
presented in April 2014 at the Build Conference, it is planned to be
released this year, and is currently in public beta testing.
During its first year of availability, upgrades to Windows 10 will be offered for
free for consumer users of Windows 7 and Windows 8.1.
The overlying goal of Windows 10 is to join
the Windows PC, Windows Phone, Windows Embedded and Xbox One product families, as well as new
product categories such as the Surface Hub and HoloLens,
around a common internal core and application ecosystem. Windows 10 also regulates
the user experience for different types of devices, and transitions between
different interface behaviours on "convertible" laptops and tablets
with keyboard docks. To improve the experience for keyboard and mouse users,
Windows 10 adds a new revision of the desktop Start menu and a virtual desktop system, and it allows modern apps to
run within windows on the desktop as well as in full-screen mode.
