Windows 10 Pro Overview Windows 10 is a series of personal computer operating systems produced by Microsoft as part of the Windows NT family of operating systems.
Windows 10 receives new versions on an ongoing basis, available to users at no additional cost
Devices in enterprise environments may receive these updates more slowly, or may take advantage of long-term support milestones, which receive only critical updates such as security patches during their ten-year lifespan of extended support.
One of the most notable features of Windows 10 is support for universal apps, an extension of the Metro-style apps first introduced in Windows 8
Universal apps can be designed to run using nearly identical code across multiple Microsoft product families—including PCs, tablets, smartphones, embedded systems, Xbox One, Surface Hub, and mixed reality.
Windows 10 also introduced the Microsoft Edge web browser, a virtual desktop system, a window and desktop management feature called Task View, support for fingerprint and facial recognition logon, new security features for enterprise environments, and DirectX 12
The Windows user interface was redesigned to allow transitions between a mouse-oriented interface and a touchscreen-optimized interface based on available input devices—especially on 2-in-1 PCs, both interfaces include an updated Start menu that combines elements of the traditional Start menu from Windows 7 with the tiles from Windows 8.
