Meet New Windows - Windows 10

"Windows 9" redirects here. For the series of Microsoft Windows computer operating systems produced from 1995 to 2000, see Windows 9x.
For Windows 10 on smartphones and sub 8? tablets, see Windows 10 (mobile).
Windows 10 is an upcoming operating system 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,[1] and is currently in
public beta testing. During its first year of availability, upgrades to Windows 10 will legally be offered at no charge for l
icensed consumer users of Windows 7 and Windows 8.1.

The goal of Windows 10 is to unify the Windows PC, Windows Phone, Windows Embedded and Xbox One product families, as well as
new product categories such as the Surface Hub and HoloLens, around a common internal core. These products will share a common,
"universal" application architecture and Windows Store ecosystem that expands upon the Windows Runtime platform introduced by Windows 8.
Windows 10 provides further integration with Microsoft services and platforms, such as the addition of Cortana (an intelligent personal assistant),
a notification system that can be synchronized between devices, and new Xbox Live features. Windows 10 will also introduce a new bundled web browser,
 Project Spartan, to replace Internet Explorer.

Windows 10's user interface is an
evolution of Windows 8's, with a
focus on transitioning between behaviors suitable for the type of device and the available input methods.
To improve the experience for keyboard and mouse users, Windows 10 adds a new revision of the desktop Start menu and a virtual desktop system,
and allows Windows Store apps to run within windows on the desktop as well as in full-screen mode. The operating system will introduce new technologies
and system components, including DirectX 12 and new frameworks for biometric authentication.
In December 2013, technology writer Mary Jo Foley reported that Microsoft was working on an update to Windows 8, codenamed Threshold after a planet
in Microsoft's Halo franchise.Similarly to "Blue" (which became Windows 8.1),[3] Foley called Threshold a "wave of operating systems" across multiple
 Microsoft platforms and services, scheduled for the second quarter of 2015. Foley reported that among the goals for Threshold was to create a unified application
 platform and development toolkit for Windows, Windows Phone and Xbox One (which all use a similar Windows NT kernel). It was speculated that Threshold would
be branded as "Windows 9".

In April 2014, at the Build Conference, Microsoft's Terry Myerson unveiled an updated version of Windows 8.1 that added the ability to run Windows Store apps inside
desktop windows, and a more traditional Start menu in place of the Start screen seen in Windows 8. The new Start menu takes after Windows 7's design by using only a
portion of the screen and including a Windows 7-style application listing in the first column. The second column displays Windows 8-style app tiles. Myerson stated
that these changes would occur in a future update, but did not elaborate.[6][7] Microsoft also unveiled the concept of a "universal Windows app," allowing Windows
Store apps created for Windows 8.1 to be ported to Windows Phone 8.1 and Xbox One while sharing a common codebase, with an interface designed for different device

form factors, and allowing user data and licenses for an app

 to be shared between multiple platforms. Windows Phone 8.1 would share nearly 90% of the common Windows Runtime APIs with Windows 8.1 on PCs

In July 2014, Microsoft's 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.[11][12] Screenshots of a Windows build which purported to be Threshold were leaked in July 2014,

showing the previously presented Start menu and windowed Windows Store apps[4] followed by further screenshot in September 2014 of a build identifying itself as

"Windows Technical Preview", numbered 9834, showing a new virtual desktop system, a notification center, and a new File Explorer.

Threshold was officially unveiled during a media event on September 30, 2014, under the name Windows 10; Myerson said that Windows 10 would be Microsoft's "most

comprehensive platform ever," providing a single, unified platform for desktop computers, laptops, tablets, smartphones, and all-in-one devices.

He emphasized that Windows 10 would take steps towards restoring user interface mechanics from Windows 7 to improve the experience for users on non-touch

devices, noting criticism of Windows 8's touch-oriented interface by keyboard and mouse users.[16][17] Despite these concessions, Myerson noted that the touch-oriented

 interface would "evolve" as well on 10.[18] In describing the changes, Joe Belfiore likened the two operating systems to electric cars,

comparing Windows 7 to a first-generation Toyota Prius hybrid, and Windows 10 to an all-electric Tesla—considering the latter to be an extension

of the technology first introduced in the former.[19] Regarding the operating system's name, Terry Myerson refused to elaborate on why Microsoft

skipped directly from Windows 8 to 10, stating only that "based on the product that's coming, and just how different our approach will be overall,

it wouldn't be right to call it Windows 9". He also joked that they couldn't call it "Windows One" (alluding to several recent Microsoft products with a

similar brand, such as OneNote, Xbox One and OneDrive) because they had already made a Windows 10.

Further details surrounding 10's consumer-oriented features were presented during another media event held on January 21, 2015, entitled "Windows 10:

The Next Chapter". The keynote featured the unveiling of Cortana integration within the operating system, new Xbox-oriented features, Windows 10 for

phones and small tablets, an updated Office Mobile suite, Surface Hub—a large-screened Windows 10 device for enterprise collaboration based upon Perceptive

Pixel technology,[20] along with HoloLens—augmented reality eyewear and an associated platform for building apps that can render "holograms" through HoloLens.

Additional information surrounding Windows 10 is expected to be announced during Build 2015

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.Continuing with this pattern, the successor to Windows Phone 8.1 unveiled at the

same event is also branded as Windows 10, and will share some user interface elements and apps with its PC counterpart.

The Windows Store app ecosystem has been revised into "Windows apps".They are made to run across multiple platforms and device

classes, including smartphone, tablet, Xbox One, and other compatible Windows 10 devices. Windows apps share code across platforms, have

responsive designs that adapt to the needs of the device and available inputs, can synchronize data between Windows 10 devices (including

notifications, credentials, and allowing cross-platform multiplayer for games), and will be distributed through a unified Windows Store.

 Developers can allow "cross-buys", where purchased licenses for an app apply to all of the user's compatible devices, rather than only

the one they purchased on (i.e. a user purchasing an app on PC is also entitled to use the smartphone version at no extra cost).

Windows 10 will also allow web apps to be packaged as Windows apps for distribution on Windows Store.

Windows 10's user interface changes its behavior depending on the type of device being used and available input methods. A new feature called Continuum

handles transitions between interface modes on convertible laptops and tablets with docking keyboards. When a keyboard is attached, users are asked if they

 want to switch to a user interface mode that is optimized for mouse and keyboard, or stay within the touch-optimized mode.[17] A new iteration of the Start

menu is used, with an application list and the "All apps" button on the left side, and live tiles on the right. The menu can be resized, and expanded into a

full-screen display, which is the default option in touch environments.

Windows 10 will incorporate multi-factor authentication technology based upon standards developed by the FIDO Alliance.[32] The operating system includes improved support for biometric authentication through the "Windows Hello" and "Passport" platforms; devices with supported cameras (requiring infrared illumination) will allow users to login with face or iris recognition, similarly to Kinect. Fingerprint recognition login is also available on devices with supported readers. Credentials are stored locally and protected using asymmetric encryption. The "Passport" platform will allow networks, software and websites to authenticate users using either a PIN or biometric login to verify their identity, without sending a password.[33] On the enterprise version of Windows 10, administrators can set up policies for the automatic encryption of sensitive data, selectively block applications from accessing encrypted data, or even outright require all software to be signed with a Microsoft key.

To reduce the storage footprint of the operating system, Windows 10 will automatically compress system files. The system can reduce the storage footprint of Windows by approximately 1.5 GB for 32-bit systems and 2.6 GB for 64-bit systems. The level of compression used will be dependent on a performance assessment performed during installations or by OEMs, which will test how much compression can be used without harming operating system performance. Furthermore, the Refresh and Reset functions will use runtime system files instead, making a separate recovery partition redundant, allowing patches and updates to remain installed following the operation, and further reducing the amount of space required for Windows 10 by up to 12 GB. These functions replace the "WIMBoot" mode introduced on Windows 8.1 Update, which allowed OEMs to configure low-capacity devices with flash-based storage to use Windows system files out of the compressed WIM image typically used for installation and recovery.[34][35][36] Windows 10 also includes a related function in its Settings app known as "Storage Sense", which allows users to view a breakdown of how their device's storage capacity is being used by different types of files, and determine whether certain types of files are saved to internal storage or an SD card by default.

Windows 10 is the first step to an era of more personal computing. This vision framed our work on Windows 10, where we are moving Windows from its heritage of enabling a single device – the PC – to a world that is more mobile, natural and grounded in trust. We believe your experiences should be mobile – not just your devices. Technology should be out of the way and your apps, services and content should move with you across devices, seamlessly and easily. In our connected and transparent world, we know that people care deeply about privacy – and so do we. That’s why everything we do puts you in control – because you are our customer, not our product. We also believe that interacting with technology should be as natural as interacting with people – using voice, pen, gestures and even gaze for the right interaction, in the right way, at the right time. These concepts led our development and you saw them come to life today.
