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 regularly receives new versions, which are available to users at no additional cost
Devices in enterprise environments may receive these updates more slowly or use long-term support phases that receive only critical updates, such as security fixes, during the extended ten-year support period.
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 across multiple Microsoft product families with nearly identical code, 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 Slideshow, support for fingerprint and facial recognition login, new security features for enterprise environments, and DirectX 12
The Windows user interface has been reworked to handle transitions between a mouse-oriented interface and a touchscreen-optimized interface based on available input devices; in particular, on the 2-in-1 PC, both interfaces include an updated Start menu that includes elements of the traditional Windows 7 Start menu with tiles from Windows 8.
