Windows 10 is an upcoming OS developed by Microsoft as part of the Windows NT family of operating systems. First presented in April 2014 at the Build Conference, it is scheduled to be released in mid-2015(in two or three) and is currently in public beta testing.
One of the most attractive thing is that Microsoft is providing all the upgrades for free for licensed users of Windows 7 & 8 for the first year. So, if you use Windows 7 or 8 you are in for a treat. The goal of Windows 10 is to unify the Windows PC, Windows Phone, Windows Embedded and Xbox.Jerry Nixon announced that Windows 10 is to be the final release of Windows, as Microsoft have decided to provide support for Windows as a service, with release updates and improvements to the operating system over time.
A major aspect of Windows 10 is a focus on harmonizing user experiences and functionality between different classes of devices, along with addressing shortcomings in the Windows user interface that was first introduced in Windows 8.
Windows 10 introduces a new default web browser, Microsoft Edge(thank god for removing IE), which Microsoft claims is the best browser for surfing in Windows. However, Internet Explorer 11 will be maintained on Windows 10 for compatibility purposes, and is deprecated in favor of Edge.
With Windows 10, Microsoft tries to strike a balance for every kind of user.
