Windows 10 Mobile is a mobile operating system developed by Microsoft, released in 2015. Although it is the successor of Windows Phone 8.1, it is an edition of Windows 10, as a result of Microsoft's plans to unify Windows families across multiple device classes.
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 that 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 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 vary depending on hardware compatibility.
Windows 10 Mobile was designed for use on smartphones and phablets running on ARM 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 began receiving updates to Windows 10 Mobile on March 17, 2016, pursuant to manufacturer and carrier support.
In October 2017, it was revealed that Microsoft had ceased active development of Windows 10 Mobile due to its low market share and the lack of third-party development for the platform, and that the operating system would only receive patches and maintenance releases until December 2019.

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.
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. 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.
During the 2015 Build keynote, Microsoft announced the middleware toolkit "Islandwood", later known as Windows Bridge for iOS, which provides a toolchain that can assist developers in porting Objective-C software (primarily iOS projects) to build as Universal Windows Apps. An early build of Windows Bridge for iOS was released as open source software under the MIT License on August 6, 2015. Visual Studio 2015 can also convert Xcode projects into Visual Studio projects. Microsoft also announced plans for a toolkit codenamed "Centennial", which would allow desktop Windows software using Win32 APIs to be ported to Windows 10 Mobile.
Project Astoria
At Build, Microsoft had also announced an Android runtime environment for Windows 10 Mobile known as "Astoria", which would allow Android apps to run in an emulated environment with minimal changes, and have access to Microsoft platform APIs such as Bing Maps and Xbox Live as nearly drop-in replacements for equivalent Google Mobile Services. Google Mobile Services and certain core APIs would not be available, and apps with "deep integration into background tasks" were said to poorly support the environment.
On February 25, 2016, after already having delayed it in November 2015, Microsoft announced that "Astoria" would be shelved. Microsoft argued that an Android emulator was ultimately redundant to the native, Objective-C toolchain, because iOS was already a primary target in multi-platform mobile development. The company also encouraged use of products from Xamarin (which they had acquired the previous day) for multi-platform app development using C# programming language instead. The Windows Subsystem for Linux (that isn't available in the Mobile version) was developed from Project Astoria.
Naming
In accordance with Microsoft's branding strategy, this operating system will be branded primarily as an edition of Windows 10, rather than "Windows Phone 10". Microsoft had begun to phase out specific references to the Windows Phone brand in its advertising in mid-2014, but critics have still considered the operating system to be an iteration and continuation of Windows Phone due to its lineage and similar overall functionality. Microsoft referred to the OS as "Windows 10 for phones and small tablets" during its unveiling, leaked screenshots from a Technical Preview build identified the operating system as "Windows 10 Mobile" and the technical preview was officially called the "Windows 10 Technical Preview for phones". Internally, the Microsoft Edge user agent on Windows 10 Mobile still contains a reference to "Windows Phone 10".
On May 13, 2015, Microsoft officially confirmed the platform would be known as Windows 10 Mobile.

Features
A major aspect of Windows 10 Mobile is a focus on harmonizing user experiences and functionality between different classes of devices--specifically, devices running the PC-oriented version of Windows 10. Under the Universal Windows Platform concept, Windows Runtime apps for Windows 10 on PC can be ported to other platforms in the Windows 10 family with nearly the same codebase, but with adaptations for specific device classes. Windows 10 Mobile also shares user interface elements with its PC counterpart, such as the updated Action Center and settings menu. During its initial unveiling, Microsoft presented several examples of Windows apps that would have similar functionality and user interfaces between Windows 10 on desktops and mobile devices, including updated Photos and Maps apps, and new Microsoft Office apps. Although marketed as a converged platform, and as with Windows Phone 8, using a Windows NT-based kernel, Windows 10 Mobile still cannot run Win32 desktop applications, but is compatible with software designed for Windows Phone 8.
Notifications can be synced between devices; dismissing a notification on, for example, a laptop, will also dismiss it from a phone. Certain types of notifications now allow inline replies. The start screen now has the option to display wallpapers as a background of the screen behind translucent tiles, rather than within the tiles. The messaging app adds support for internet-based Skype messaging alongside SMS, similarly to iMessage, and can synchronize these conversations with other devices. The camera app has been updated to match the "Lumia Camera" app previously exclusive to Lumia products, and a new Photos app aggregates content from local storage and OneDrive, and can perform automatic enhancements to photos. The on-screen keyboard now contains a virtual pointing stick for manipulating the text editing cursor, a dedicated voice input button, and can be shifted towards the left or right of the screen to improve one-handed usability on larger devices.
Windows 10 Mobile supports "Continuum", a feature that allows supported devices to connect to an external display, and scale its user interface and apps into a "PC-like" desktop interface with support for mouse and keyboard input over USB or Bluetooth. Devices can connect directly to external displays wirelessly using Miracast, via USB-C, or via docking station accessories with USB ports, as well as HDMI and DisplayPort outputs.
A new iteration of the Office Mobile suite, Office for Windows 10, is also bundled. Based upon the Android and iOS versions of Office Mobile, they introduce a new user interface with a variation of the ribbon toolbar used by the desktop version, and a new mobile version of Outlook. Outlook utilizes the same rendering engine as the Windows desktop version of Microsoft Word. Microsoft Edge replaces Internet Explorer Mobile as the default web browser.
Release
Windows 10 Mobile's first-party launch devices--the Lumia 950, Lumia 950 XL, and Lumia 550--were released in November 2015 being the first phones to ship with Windows 10 Mobile. Monthly updates to the OS software are being released to address bugs and security issues. These updates are distributed to all Windows 10 Mobile devices and do not require the intervention of a user's wireless carrier in order to authorize their distribution. Firmware upgrades will still require authorization by the user's carrier.
The Windows Insider program, adopted to provide a public beta for the PC version of Windows 10, is used to provide a public beta version of Windows 10 Mobile for selected devices. A build released on April 10, 2015 was to support most second and third generation Lumia products, but the Lumia 930, Lumia Icon, and Lumia 640 XL did not receive the update due to scaling bugs, and delivery was suspended as a whole due to backup and restore issues on some models. An update to the Windows Phone Recovery Tool resolved these concerns, and delivery of Windows 10 updates was restored to the 520 with build 10052, and to the 640 with build 10080.
Build number 10136 was released on June 16, 2015, with a "migration bug" that required that existing devices on build 10080 be reverted to Windows Phone 8.1 using the Recovery Tool before the installation of 10136 could proceed. This migration bug was fixed a week later with the release of build 10149. Mobile builds of the Redstone branch till 14322 were halted for the device Lumia 635 (1 GB RAM) due to bugs.
Upgrade release
Some Windows Phone 8.1 smartphones can be upgraded to Windows 10, pursuant to hardware compatibility, manufacturer support, and carrier support. Not all phones can receive the update nor support all of its features. Microsoft originally stated that stable upgrades for Windows Phone 8.1 devices would be released in December 2015; however, the release was ultimately delayed to March 17, 2016. Among first-party devices, only the Lumia 430, 435, 532, 535, 540, 635 (1 GB RAM), 640, 640 XL, 735, 830, 929, 930 and 1520 are supported. The only third-party devices supported are the BLU Products Win HD w510u and Win HD LTE x150q, and the MCJ Madosma Q501. Windows 10 Mobile does not officially support any HTC devices (HTC One M8 for Windows, HTC Windows Phone 8X, HTC Windows Phone 8S), although the HTC One M8 for Windows could be upgraded to the public release version of Windows 10 Mobile through the Windows Insider program. While Microsoft stated that the Nokia Lumia Icon may be upgraded at a later date, the company stated that there will not be a second wave of officially supported devices. Microsoft also removed statements which promoted the BLU Win JR LTE as being compatible with Windows 10.
Microsoft originally stated that all Lumia smartphones running Windows Phone 8 and 8.1 would receive updates to 10, but Microsoft later reiterated that only devices with the "Lumia Denim" firmware revision and at least 8 GB of internal storage would receive the upgrade. In February 2015, Joe Belfiore stated that Microsoft was working on support for devices with 512 MB of RAM, (such as the popular Nokia Lumia 520), but these plans have since been dropped. Upon the official upgrade release, some Lumia models, particularly the Lumia 1020 and 1320, were excluded despite meeting the previously announced criteria. Microsoft cited poor user feedback on the performance of preview builds on these models as reasoning. On 17th October 2017, Nearly 2 years after the Windows 10 release, Microsoft released an Over-The-Cable (OTC) Updater tool to bring all Lumias up to date to the latest supported Windows 10 build, even older 512mb and 1gb ram unlocked devices such as the 520,620,720,925,920 etc. which were updated using the tool to Build 10586 (November Update).
Reception
Reception of Windows 10 Mobile has been mixed. The Verge was disappointed with the direction that Windows 10 Mobile has taken, describing it as feeling "buggy and unfinished". Tech Radar praised the OS for its design, but noted that the lack of apps was the "biggest let-down on Windows Phone and Windows 10 Mobile alike."
Windows 10 Mobile has also been criticized for its poorer performance than Windows Phone 8.1 on some devices. After many user complaints, Microsoft started allowing users to downgrade from Windows 10 to Windows Phone 8.1.
Sales
Sales have decreased rapidly since its release, to the point of Windows 10 Mobile being considered irrelevant in the mobile operating system landscape.
Devices
As with Windows Phone, Windows 10 Mobile supports ARM system-on-chips from Qualcomm's Snapdragon line. In March 2015, Ars Technica reported that the operating system will also introduce support for IA-32 system-on-chips from Intel and AMD, including Intel's Atom x3 and Cherry Trail Atom x5 and x7, and AMD's Carrizo. However, as of November 2016, it did not happen.
Minimum specifications for Windows 10 Mobile devices are similar to those of Windows Phone 8, with a minimum screen resolution of 800×480 (854×480 if software buttons are in use), 1 GB of RAM and 8 GB of internal storage. Owing to hardware advancements and the operating system's support for tablets, screen resolutions can now reach as high as QSXGA resolution (2560×2048) and further, as opposed to the 1080p cap of Windows Phone 8. The minimum amount of RAM required is dictated by the screen's resolution; screens with a resolution 800×480 or 960×540 and higher require 1 GB, 1920×1080 (FHD) or 1440×900 and higher require 2 GB, and 2560×1440 and higher require 3 GB.
Microsoft unveiled flagship Microsoft Lumia smartphones during a media event on October 6, 2015, including Lumia 950, Lumia 950 XL, and the low-end Lumia 550.
Version history
Threshold
Microsoft announced Windows 10 Mobile during their January 21, 2015 event "The Next Chapter". The first Windows 10 Mobile build was rolled out on February 12, 2015 as part of the Windows Insider Program to a subset of mobile devices running Windows Phone 8 and 8.1. As with the desktop editions of Windows 10, this initial release was codenamed "Threshold", it was part of both the "Threshold 1" and "Threshold 2" development cycles. Windows 10 Mobile launched with the Microsoft Lumia 550, 950 and 950 XL. The rollout for Windows Phone 8.1 devices started March 17, 2016.
Anniversary Update
On February 19, 2016, Microsoft restarted the rollout of full builds for the first feature update, officially known as the "Anniversary Update" or "Version 1607", codenamed "Redstone 1". Like the start of the previous wave, the first builds were not available to all devices that were included in the Windows Insider Program.
Creators Update
The Creators Update (named after the equivalent update to Windows 10 for PC), also known as Redstone 2, was first previewed on the Insider branch on August 17, 2016. and began deployment on April 25, 2017. It features mainly minor feature additions, including an e-book reader within Edge, the ability to turn off the phone screen when using Continuum mode on an external display, SMS support in Skype, SD card encryption, and other changes. Despite the platform's synergy with Windows 10 for PCs, some of its features (such as Night Light and Paint 3D) were excluded. Only eleven existing Windows 10 Mobile devices were offered upgrades.
- Alcatel IDOL 4S
- Alcatel OneTouch Fierce XL
- HP Elite x3
- Lenovo Softbank 503LV
- MCJ Madosma Q601
- Microsoft Lumia 550
- Microsoft Lumia 640 / 640XL
- Microsoft Lumia 650
- Microsoft Lumia 950 / 950 XL
- Trinity NuAns Neo
- VAIO VPB051
Fall Creators update
Around the time that the Creators Update was finalized, Windows Insider users began to be issued builds on a branch known as "feature2". Feature 2 is a separate branch from the main Redstone 3-branch (branded as "Fall Creators Update") for Insiders, the branch corresponding to the next feature update. Microsoft stated that there were no plans to move Windows 10 Mobile to be in sync with the other Windows 10-platforms just yet; media outlets considered this decision to be a sign that Microsoft was beginning to wind down active development of Windows 10 Mobile beyond maintenance releases, as development was no longer directly in sync with the PC version.
In early-June 2017, a private build, briefly deployed by accident by Microsoft, revealed work on an updated interface for Windows 10 Mobile known as "CShell" ("composable shell"), an implementation of the Windows shell across device classes using a modular system. The build featured a Start screen, Action Center, and Continuum desktop interface that were nearly identical in functionality and appearance to their equivalents on Windows 10 for PC. However, this iteration of the operating system was no longer backwards compatible with Windows Phone Silverlight apps.
On October 8, 2017, Microsoft executive Joe Belfiore revealed that the company would no longer actively develop new features or hardware for Windows phones, citing its low market share, and the resultant lack of third-party software for the platform. Microsoft had largely abandoned its mobile business, having laid off the majority of Microsoft Mobile employees in 2016, and having focused software efforts on providing apps and services compatible with Android and iOS instead. Development of Windows 10 Mobile will be limited to maintenance releases and patches.
