24H2 notably introduces the first Windows 11 based Long-Term Servicing Channel (LTSC) editions, along with new subscription variants of IoT Enterprise editions (both LTSC and non-LTSC). [42]

Furthermore, 24H2 introduces modified system requirements, for some systems, for the first time since the release of Windows 11, as follows:

Insider releases

Windows Insider Preview builds are delivered to Insiders in four different channels. Insiders in the Dev and Canary Channel receive updates prior to those in the Beta Channel but might experience more bugs and other issues. Insiders in the Release Preview Channel do not receive updates until the version is almost available to the public but are comparatively more stable.

On February 3, 2022, Microsoft changed its plans on how they delivered builds for Windows Insiders, with Dev and Beta Channels being "parallel" active development branches, giving an option to switch from Dev to Beta Channel for a limited time. The Dev Channel builds are meant for upcoming and experimental features that may never release to general availability, whereas the Beta Channel builds are the "feature complete" builds that will make its way to the general availability for the specific Windows 11 release. [46]

On March 6, 2023, Microsoft announced that the Dev Channel will be rebooted, and existing insiders will be moved to the new Canary Channel. [47] [48] Two days later, insiders transitioned from Dev to Canary received the first build in the existing 25000 series builds starting from build 25314 [49] while new insiders in the rebooted Dev Channel received the first build in the new 23000 series builds starting from build 23403. [50]

Dev Channel

On September 2, 2021, Microsoft announced that Windows Insiders in the Dev Channel will receive builds directly from the rs_prerelease branch, which are not matched to a specific Windows 11 release. The first build released under this strategy, build 22449, was made available to Insiders on the same day. [51]

Aside from the rs_prerelease (21H2 string) branch, Insiders in the Dev Channel would receive builds compiled from other branches within certain periods of time: ni_release (builds 22557 to 22616 – 22H2 string in former Dev), ni_prerelease (builds 23403 to 23620 – 22H2 string in rebooted Dev) and ge_release (builds 26052 to 26100 – 24H2 string) and TBA (build 26120 and later).

Canary Channel

Aside from the rs_prerelease (22H2 string) branch, Insiders in the Canary Channel would receive builds compiled from other branches within certain periods of time: zn_release (builds 25375 to 26040 – 23H2 string), ge_release (builds 26052 to 26100 - 24H2 string) and ge_prerelease (build 26200 and later).

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 as part of 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 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 10 has several editions, all with varying feature sets, use cases, or intended devices. Certain editions are distributed only on devices directly from an original equipment manufacturer (OEM), while editions such as Enterprise and Education are only available through volume licensing channels. Microsoft also makes editions of Windows 10 available to device manufacturers for use on specific classes of devices, including IoT devices, and previously marketed Windows 10 Mobile for smartphones.

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.
