Windows 11 version history

Windows 11 is a major release of the Windows NT operating system developed by Microsoft that was released in October 2021. Starting with Windows 10, Microsoft described Windows as an "operating system as a service" that would receive ongoing updates to its features and functionality, augmented with the ability for enterprise environments to receive non-critical updates at a slower pace or use long-term support milestones that will only receive critical updates, such as security patches, over their five-year lifespan of mainstream support.

This is the last version of Windows 11 where the DNS Cache Service DNScache is used as an optional service.

The update has reach end of service on November 11, 2025 for Home, Pro, Pro Education, Pro for Workstations and SE editions.[46] The Enterprise, Enterprise multi-session, IoT Enterprise and Education editions will reach end of service on November 10, 2026.[47]

Version 24H2 (2024 Update)

The Windows 11 2024 Update[48] (also known as version 24H2[49][50][51] and codenamed "Hudson Valley"[52]) is the third major update to Windows 11. It carries the build number 10.0.26100.

The first preview was released to Insiders who opted into the Canary and Dev Channels on February 8, 2024. The update began rolling out for Copilot Plus PCs on June 15, 2024.[53] As of build 26052, the version string has been changed from "23H2" to "24H2". The update began rolling out to all users on October 1, 2024.[54][51]

The update 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).[55]

For the first time since the release of Windows 11, version 24H2 introduces modified system requirements:

  • A x86-64-v2 CPU supporting SSE4.2 and POPCNT CPU instructions is now required, otherwise the Windows kernel is unbootable.[56][57] (Only affecting systems bypassing the requirements, along with all 24H2 IoT Enterprise editions.)
  • IoT Enterprise editions (LTSC and non-LTSC) have officially eliminated a TPM and UEFI requirement, and lowers the minimum DirectX version to 10 from 12, which was previously required on 23H2.[55][58]
  • The new IoT Enterprise LTSC edition lowers the minimum required RAM to 2 GB, and storage space to 16 GB.[55][58]
  • ARMv8.1 is now required for ARM variants, dropping unofficial support for ARMv8.0.[59] On ARMv8.0 CPUs, the Windows kernel is unbootable.
  • ARM variants drop support for 32-bit ARM applications.[60] Only 64-bit ARM applications will run.

Windows 11, version 24H2, notably, has a longer than usual list of known issues; some require updated drivers to fix, while others have yet to be fixed as of February 2025. E.g., broken biometrics and camera support on a limited number of devices, and some older games and applications not functioning properly or not working at all; e.g., Asphalt 8 (resolved since March 19, 2025), Dirac audio improvement software (if cridspapo.dll is utilized), and AutoCAD 2022.[61][62][63]

New features include:

  • Windows 11 HDR background support for HDR monitors[64]
  • Support for Wi-Fi 7 (802.11be), which enhances data transfer speeds, along with new user interface elements to refresh the list of Wi-Fi networks and indicate scan progress[65]
  • Support for Bluetooth LE audio[65]
  • Windows 11 Search adds the ability to search for documents and photos using descriptive phrases instead of just file names[64]
  • Auto Super Resolution boosts frame rates for certain games while maintaining visual quality; requires a Copilot+ PC with a Snapdragon X processor[65]
  • Windows Recall (preview) which lets users find content they have already viewed. Delayed and only being released in preview status due to the amount of negative feedback that it received when it was first introduced, this feature requires Windows Hello for secure access (because it may display sensitive data) and can be disabled.[64]
  • Windows Studio Effects for cameras and microphones in supported applications including Microsoft Teams, Zoom, Google Meet, Skype, and the Microsoft Camera app; effects include backdrop blur, eye correction, portrait lighting, and illustrative filters[65]
  • Windows Click to Do (preview): an interactive PC screen overlay with several functions for tasks including text summarizing or sending, blending backgrounds in pictures, and using Microsoft Bing for visual search[64]

Dropped features include:

  • Ability to disable DNS Cache Service due to the fact that this service is mandatory to access the internet like opening a webpage through a browser, even though ping requests still works when dnscache is disabled, for practical purposes the system will lose internet access completely, thus making standard navigation impossible.[45]

The update will reach end of service on October 13, 2026, for Home, Pro, Pro Education and Pro for Workstations editions.[66] The update is also the last to be available to the SE edition, which will reach end of support alongside consumer editions.[67][68] The Enterprise, Enterprise multi-session, IoT Enterprise and Education editions will reach end of service on October 12, 2027.[66] The Enterprise LTSC and IoT Enterprise LTSC editions will reach end of service on October 9, 2029, and October 10, 2034, respectively.[66]

Version 25H2 (2025 Update)

The Windows 11 2025 Update[69] (also known as version 25H2[70][71] and codenamed "Hudson Valley 2") is the fourth and latest major update to Windows 11. It is shipped as an enablement package for the Windows 11 2024 Update, and carries the build number 10.0.26200.

The first preview was released to Insiders who opted in to the Dev Channel on June 27, 2025, along with the version string being changed from "24H2" to "25H2".[70] The update began rolling out on September 30, 2025.[72][69]

Version 26H1

The Windows 11, version 26H1 is the fifth major update to Windows 11. It was released on February 10, 2026.

The first preview was released to Insiders who opted in to the Canary Channel on November 7, 2025, along with the version string being changed from "Dev" to "26H1".[73]

Version 26H1 is a platform-specific support release that only includes changes to support devices with certain processors,[73] with the Qualcomm Snapdragon X2 being the only confirmed case as of January 25, 2026.[74]

Insider releases

Further information: Windows Insider

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.[75]

On March 6, 2023, Microsoft announced that it was restructuring the preview channels in the Windows Insider Program. The Dev Channel would continue to test early versions of new features, and existing insiders were moved to the new Canary Channel that would primarily test changes to the kernel.[76][77]
