Windows 10 Mobile is a mobile operating system developed by Microsoft. It is an iteration of the Windows Phone product line and a successor to Windows Phone 8.1,〔 but is marketed as being an edition of Windows 10, Microsoft's operating system for personal computers, as part of Microsoft's plans to unify their platforms into one converged operating system. Windows 10 Mobile aims to provide greater consistency with its counterpart for personal computers, including more extensive synchronization of content, a new universal application platform allows one app to run on multiple Windows 10 devices such as PCs, mobile devices and Xbox, as well as the capability, on supported hardware, to connect devices to an external display and use a "PC-like" interface with mouse and keyboard input support. Microsoft has built tools for developers to easily port some Android and iOS apps with minimal modifications. Windows Phone 8.1 smartphones are eligible for upgrade to Windows 10 Mobile, pursuant to manufacturer and carrier support. Some features may vary depending on hardware compatibility. Windows 10 Mobile is designed for use on smartphones and small tablets under eight inches in screen size, running on ARM as well as IA-32 processor architectures. Windows 10 Mobile entered public beta for selected Lumia brand smartphones on February 12, 2015. The first Lumia smartphones powered by Windows 10 Mobile were released on November 20, 2015, while eligible Windows Phone devices are scheduled to begin receiving updates to Windows 10 Mobile in the following weeks, pursuant to manufacturer and carrier support. == Development == Microsoft had already begun the process of unifying the Windows platform across device classes in 2012; Windows Phone 8 dropped the Windows CE-based architecture of its predecessor, Windows Phone 7, for a platform built upon the NT kernel that shared much of the same architecture with its PC counterpart Windows 8 including file system (NTFS), networking stack, security elements, graphics engine (DirectX), device driver framework and hardware abstraction layer. At Build 2014, Microsoft also unveiled the concept of "universal" Windows apps. With the addition of Windows Runtime support to these platforms, apps created for Windows 8.1 could now be ported to Windows Phone 8.1 and Xbox One while sharing a common codebase with their PC counterparts. User data and licenses for an app could also be shared between multiple platforms. In July 2014, Microsoft's then-new CEO Satya Nadella explained that the company was planning to "streamline the next version of Windows from three operating systems into one single converged operating system for screens of all sizes," unifying Windows, Windows Phone, and Windows Embedded around a common architecture and a unified application ecosystem. However, Nadella stated that these internal changes would not have any effect on how the operating systems are marketed and sold.〔(【引用サイトリンク】url=http://www.pcmag.com/article2/0,2817,2461253,00.asp )〕〔(【引用サイトリンク】url=http://www.techradar.com/news/software/operating-systems/why-did-microsoft-choose-windows-10-instead-of-windows-9--1267366 )〕 On September 30, 2014, Microsoft unveiled Windows 10; Terry Myerson explained that Windows 10 would be Microsoft's "most comprehensive platform ever," promoting plans to provide a "unified" platform for desktop computers, laptops, tablets, smartphones, and all-in-one devices.〔(【引用サイトリンク】url=http://blogs.seattletimes.com/brierdudley/2014/09/29/microsoft-previews-windows-9/ )〕 Windows 10 on phones was publicly unveiled during the ''Windows 10: The Next Chapter'' press event on January 21, 2015; unlike previous Windows Phone versions, it would also expand the platform's focus to small, ARM-based tablets. Microsoft's previous attempt at an operating system for ARM-based tablets, Windows RT (which was based upon the PC version of Windows 8) was commercially unsuccessful. Windows RT devices will receive a different update with some of the features of Windows 10 for PC. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Windows 10 Mobile」の詳細全文を読む スポンサード リンク
