Microsoft Windows is a product line of proprietary graphical operating systems developed and marketed by Microsoft. It is grouped into families and sub-families that cater to particular sectors of the computing industry – Windows (unqualified) for a consumer or corporate workstation, Windows Server for a server and Windows IoT for an embedded system. Defunct families include Windows 9x, Windows Mobile, Windows Phone, and Windows Embedded Compact.
The Microsoft Store is a digital distribution platform operated by Microsoft. It was created as an app store for Windows 8 as the primary means of distributing Universal Windows Platform apps. With Windows 10 1803, Microsoft merged its other distribution platforms into Microsoft Store, making it a unified distribution point for apps, console games, and digital videos. Digital music was included until the end of 2017, and E-books were included until 2019.
Windows 10 is a major release of Microsoft's Windows NT operating system. It is the direct successor to Windows 8.1, which was released nearly two years earlier. It was released to manufacturing on July 15, 2015, and later to retail on July 29, 2015. Windows 10 was made available for download via MSDN and TechNet, as a free upgrade for retail copies of Windows 8 and Windows 8.1 users via the Microsoft Store, and to Windows 7 users via Windows Update. Windows 10 receives new builds on an ongoing basis, which are available at no additional cost to users, in addition to additional test builds of Windows 10, which are available to Windows Insiders. Devices in enterprise environments can receive these updates at a slower pace, or use long-term support milestones that only receive critical updates, such as security patches, over their ten-year lifespan of extended support. In June 2021, Microsoft announced that support for Windows 10 editions which are not in the Long-Term Servicing Channel (LTSC) will end on October 14, 2025.
Microsoft Edge is a proprietary cross-platform web browser created by Microsoft. Released in 2015 along with both Windows 10 and Xbox One, it was initially built with Microsoft's own proprietary browser engine, EdgeHTML, and their Chakra JavaScript engine. Later on, it was ported to Android and iOS as a fork of Google's Chromium open-source project. In late 2018, Microsoft announced it would completely rebuild Edge as a Chromium-based browser with Blink and V8 engines, which allowed the browser to be ported to macOS. The new Edge was publicly released in January 2020, and on Xbox platforms in 2021. Microsoft has since terminated security support for the original browser. Edge is also available on older Windows versions until early 2023, as well as Linux.
Windows 10 Mobile is a discontinued mobile operating system developed by Microsoft Mobile. First released in 2015, it is the successor to Windows Phone 8.1, but was marketed by Microsoft as being an edition of its PC operating system Windows 10.
Windows Insider is an open software testing program by Microsoft that allows users globally who own a valid license of Windows 11, Windows 10, or Windows Server to register for pre-release builds of the operating system previously only accessible to software developers.
Windows Server 2016 is the twelfth release of the Windows Server operating system developed by Microsoft as part of the Windows NT family of operating systems. It was developed alongside Windows 10 and is the successor to the Windows 8.1-based Windows Server 2012 R2. The first early preview version became available on October 1, 2014 together with the first technical preview of System Center. Windows Server 2016 was released on September 26, 2016 at Microsoft's Ignite conference and reached general availability on October 12, 2016.
Windows 10 introduced a number of new elements, including the option to use a touch-optimized interface or a traditional desktop interface similar to that of Windows 7 along with live tiles from Windows 8. However, unlike previous versions of Windows, where most, if not all, major features for that release were completed by its RTM, Windows 10 continues to receive major features and changes beyond its initial release to market. Microsoft describes Windows 10 as an "operating system as a service" that will receive ongoing updates to its features and functionality. This is supplemented with the ability for enterprise environments to receive non-critical updates at a slower pace, and to use long-term support milestones that will only receive critical updates, such as security patches, over their ten-year lifespan of support.
