Xbox system software

The Xbox system software is the operating system developed exclusively for the Xbox consoles. Across the four generations of Xbox consoles, the software has been based on a version of Microsoft Windows and incorporating DirectX features optimized for the gaming console. The user interface, the Xbox Dashboard, provides access to games, media players, and applications, and integrates with Xbox Live for online functionality.
Though initial iterations of the software for the original Xbox and Xbox 360 were based on heavily-modified versions of Windows, the newer consoles feature operating systems that are highly compatible with Microsoft's desktop operating systems, allowing for shared applications and ease-of-development between personal computers and the Xbox line.
Common features.
Across all four generations of the Xbox platform, the user interface of the system software has been called the Xbox Dashboard. While its appearance and detailed functions have varied between console generations, the Dashboard has provided the user the means to start a game from the optical media loaded into the console or off the console's storage, launch audio and video players to play optical media discs, or start special applications for the Xbox such as streaming media services from third parties. The Dashboard also provides a menu of settings and configuration pages for the console that the user can adjust.
The Dashboard has supported integration with the Xbox Live service since November 2002. Xbox Live provides online functionality to the Xbox, including friends list, game achievement tracking, matchmaking support for online games, in-game communications, and a digital game storefront. While some portions of the Xbox Live service are free, a subscription-tier Xbox Live Gold is generally required to play most multiplayer games on the console.
Starting with the Xbox 360 and continuing through its current consoles, Microsoft has offered a means for users to opt into a beta test version of the console's system software. When first launched for the Xbox 360 in September 2010, this was called the Xbox Live Preview Program, and initially required an invitation from Microsoft after applying for the program. On the release of the Xbox One in 2014, the program was renamed to Xbox Preview Program, and Microsoft made this program open to all rather than restricting through invitation. Later in November 2016 rebranded to the Xbox Insider Program, corresponding to the similar Windows Insider program for those testing its computer operating system. With the Xbox Insider Program, testing not only included updates to the system software but upcoming game and application patches from both first and third-parties.
Each iteration of the Xbox software has brought some form of backward compatibility to the newer console. On the Xbox 360, selected original Xbox console games could be played through emulation after downloading an emulation profiles to local storage. The Xbox One was not initially shipped with backward compatibility support, but was later added by January 2015 by another emulator to support selected Xbox 360 games, with hundreds of titles added over the following years. A similar emulator was developed and released in October 2017 for the Xbox One for a limited selection of original Xbox console games. Achieving Xbox One-backward compatibility on the Xbox Series X and Series S was a target goal for the newer consoles, and as such, these new consoles are fully backward compatible with all games in the Xbox One library with the exception of those requiring Kinect support. The supported list includes the Xbox and Xbox 360 games that were playable via emulation on the Xbox One.
Xbox (first generation) software.
The original Xbox runs a custom operating system which is based on a heavily modified version of Windows 2000, an approach that Microsoft engineer Don Box called "fork and run". It exports APIs similar to those found in Microsoft Windows, such as Direct3D. While Windows 2000 was built for multitasking of multiple applications including memory paging, the Xbox console was planned to only run one application at a time, and these features were removed for the Xbox software. When loading a game, the operating system would unload itself to give all of the console's resources to the game, and then when the player left the game, the operating system would load back up again.
Xbox Live support was not originally part of the system software as shipped in 2001, but added later in November 2002. While the Xbox was still being supported by Microsoft, the Xbox Dashboard was updated via Live several times to reduce cheating and add features.
Microsoft released a dynamic background for its current Xbox One and Xbox Series X/S system software in May 2021 that is based on the original Xbox system software appearance.
The original Xbox operating system source code was leaked in 2020.
Xbox 360 software.
The Xbox 360 system software was also a modified version of Windows 2000, expanding beyond the original Xbox console's operating system. This would prove troublesome for Microsoft from multiple directions. For the Xbox division, it made it difficult to bring in other Microsoft applications like Internet Explorer and Silverlight which had to be modified to work on the Xbox software. For Microsoft, the separate fork of these apps for the Xbox 360 and for the versions they were developing for the mobile-based Windows CE environment became difficult to maintain. These complexities led Microsoft towards its "Windows Everywhere" approach around 2010, reviewing all the dependencies within the desktop, Xbox, and mobile versions of Windows atop the MinWin process and creating a CoreSystem that contained the basic functionality of Windows that could be ported to other systems.
User interface.
Microsoft released the Xbox 360 console on November 22, 2005, a whole year earlier than both the Sony PlayStation 3 and Nintendo Wii. Having the advantage of the lead, Microsoft was able to experiment with various customization options for the consumer's individual consoles. The ability to customize the way the console looked with various themes to fit the front and sides of it was something very different for home console users. In system, the Xbox 360 Dashboard had the ability to have multiple profiles with password on the same console with each user being able to customize the dashboard to exactly fit their own unique style. There were premium themes available for purchase on the Xbox Live Marketplace apart from the default styles. Originally there were five tabs or sections known as the "blades" for the Xbox 360 menu, namely the Marketplace, Xbox Live, Games, Media and System. In scrolling from left to right, each section would have a different-colored background signifying its own unique area but users also had the option to change all sections to one background color as well.
In 2008 however, when the gaming scene changed dramatically because of the competitions with the PlayStation 3 and the Wii, a new Xbox Dashboard titled the New Xbox Experience (NXE) was launched, which features major changes in both the user interface and other functionalities. The new user interface had a navigation system similar to that of Windows Media Center. It contained a New pop-up/in-game Live Guide, using a redesigned version of the "blades" interface, a tabbed interface that featured five "blades". Also, users were able to create personalized Avatars, essentially mini characters of themselves. Furthermore, selecting an avatar is now required by the Xbox Live service. A slightly modified version of NXE was released in 2010 alongside the Kinect as to provide support for motion-sensing controls of the Dashboard. 
A full reworking of the interface was released in late 2011 based on the Metro design inspired by Windows Phone. The many enhancements that were included with this update pushed the system to a more modernized interface and improved features that pushed the envelope for social gaming and media.
Multimedia features.
While the Xbox 360 console is primarily designed to play games just like other video game consoles, it can be used as a media player too. Similar to the PlayStation 3 from Sony, Xbox 360 has media center capabilities built in, so it is relatively easy to set up. With the Xbox 360 users can also copy videos directly to the hard drive, or play via a USB stick. There are two ways to watch videos on Xbox 360. The first is to download videos from the Xbox Live Marketplace. Some of these videos are available for free while others have to be paid. Microsoft is in control of what videos are available through the Xbox Live Marketplace. The second is to stream videos from a Windows Media Center PC by using Xbox 360 as a Media Center Extender. In this way users are in control of what videos they want to watch, however there are restrictions on what kind of video they can playback. More specifically, it only supports playback of DVR-MS, MPEG-1, MPEG-2 and WMV videos. Every Xbox 360 can play DVD movies out of the box using the built-in DVD drive, with no additional parts necessary, although the user may control everything with an optional remote. There are other improvements to the experience on the Xbox 360 over the original Xbox too, including the ability to upscale the image so it will look better. Progressive scan is another feature of the DVD output in the Xbox 360 that produces smoother output when playing movies on televisions that support high definition, although using a dedicated DVD player would offer even more features and sound quality.
Xbox One and Xbox Series X/S.
System.
The Xbox One console system software contains a heavily modified Hyper-V hypervisor (known as NanoVisor) as its host OS and two partitions. One of the partitions, the "Exclusive" partition is a custom virtual machine (VM) for games; the other partition, the "Shared" partition is a custom VM for running multiple apps including the OS.
As part of its ongoing "Windows Everywhere" approach, Microsoft revamped the operating system in the Xbox One to be closer to its current Microsoft Windows products as to provide greater compatibility between personal computers and the Xbox line. The OS was based on Windows 8 Core at the Xbox One launch in 2013. The UI maintained the same "Metro" design that had been used in the last Xbox 360 update, and which resembled the desktop Windows 8 interface.
In November 2015, Microsoft released the "New Xbox One Experience" which replaced the base system with Windows 10 Core, allowing Universal Windows Platform apps to be available on Xbox One. According to the current head of Microsoft's Gaming division, Phil Spencer, "The importance of entertainment and games to the Windows ecosystem has become really prevalent to the company". The program that Microsoft launched allows developers to build a single app that can run on a wide variety of devices, including personal computers and Xbox One video game consoles. According to "Polygon", Microsoft removed the distinction between Xbox One and Windows PC, and the software has been called "Windows 10 on Xbox One".
Since 2016, all Xbox One consoles could be updated to include a development kit for universal Windows applications on Xbox One, with official support for the platform and Cortana coming in summer 2016.
As Microsoft continued to refine Windows 10 with the Fluent Design System, the Xbox One interface was also modified to reflect these changes by 2017. Microsoft has since continued to refine this interface to add and remove integrated features, such as inclusion of Xbox Game Pass support and removal of Cortana voice commands. Ahead of the release of the Xbox Series X and Series S consoles in November 2020, Microsoft updated the Xbox One software to reflect changes in the Dashboard that would also be present in the newer consoles. This included improved performance in some of the storefront features and readability improvements to the interface, which were also propagated across Xbox Game Pass and mobile apps.
User interface.
The system software's interface uses a geometrical placement of squares and rectangular items that scrolls as a continuous vertical line, using the Metro design language that is also seen in Windows 8, Windows 10, and other Microsoft products. By default, the dashboard is divided into "Home", "Community", "Mixer", "Game Pass" and "Store" sections; the "Home" section contains a recent apps and games list. The "Community" section allows users to view their friends' in-game activities and captures, post status updates, as well as view trending content. The "Mixer" section shows an overview on streams on Microsoft's own Mixer service, while the "Store" section serves as a portal to the games, video, music, and app marketplaces. In general, the top level menu of the Xbox One feels a lot less cluttered than the Xbox 360's dashboard. For example, the friends tab has been removed and replaced with a dedicated app that users can load up to see what their connections are doing. There are a couple of columns for settings options and an area for "pinned" favorites, a "main" screen showing current and recent apps and games that the user played or used, and a small "What's New" section highlighting some recently added content. In total, the interface is very clean and sparse. Microsoft also introduced a new way to multitask called Snap, which allows Xbox One users to open multiple panes in a single window.
When Microsoft upgraded the Windows 8-based Core to a Windows 10-based one, they made a tour of the new user interface up on Xbox Wire, promising faster, easier navigation, improved community features and, the return of Xbox Avatars. The main feature on the home screen is a list of the most recently played games. Selecting any given title will give users more information about announcements, achievements, social activity and so forth. It is also more focused on the actual games they are playing, which is part and parcel of the company's new direction under Phil Spencer, the current head of Microsoft's Xbox division.
Multimedia features.
While like other video game consoles the Xbox One is primarily designed for playing games, it is more than a game console. It is an entertainment hub for games, television, music, and videos. Mainly the console focuses on functionality and entertainment as a whole. At Gamescom 2014 Microsoft unveiled a new plan to remedy this and make earnest on the Xbox One's label as the "all-in-one entertainment" solution by way of expanding its media support. The Xbox One's media player is quite similar to the Xbox 360's playback suite in terms of form and function, however the newer console now supports more than 30 formats including the MKV container and GIF files. The Xbox One console also does some unique things. For example, its owners can control their television broadcasts using the device, as well as use it as a functioning DVR. Apart from streaming music and videos via Play (Charms > Devices > Play), there is also a networked approach. There are two primary ways to do this. The first is to stream media from a computer or tablet, and the second is to play it directly off of a USB flash drive. The advantage of this method over the Play system is that users can do it all from wherever they sit via the Xbox One, instead of sending the video from a PC to their console. Aside from multimedia files, Xbox One plays CDs, DVDs and Blu-ray Discs, and it also comes with DLNA and MKV support, which means that downloaded video files can be streamed via the PC or transported via external hard drive and USBs. Meanwhile, the interactive TV Guide allows users to turn on and control a television with their voice. Furthermore, the system comes with a comprehensive range of applications related to multimedia features. In the United States, video channels include Amazon Instant Video, Crackle, Hulu Plus and Netflix. Microsoft announced that the Xbox One was awarded for its multimedia capabilities at the 66th Annual Technology & Engineering Emmy Awards in early 2015, and the prize was given for the Xbox One's television-on-demand functions.
Updates.
Microsoft aims to release frequent updates to the Xbox One console, mainly containing new or improved features and faster installation and loading times for games and apps. Along with introducing improvements and fixes for native console apps and software, the monthly updates to the Xbox One system software introduce major features that are voted on or requested by the community, though some months have included more than one update. Starting in February 2014, beta releases of updates are tested before going live to check for unwanted bugs and stability.
