Announcing Windows 11 Insider Preview Build 26120.3964 (Beta Channel)

Hello Windows Insiders,

Today we are releasing Windows 11 Insider Preview Build 26120.3964 (KB5058496) to the Beta Channel for Windows Insiders on Windows 11, version 24H2.

REMINDER: Build 22635.5305 was the last update released to the Beta Channel based on Windows 11, version 23H2. All Insiders in the Beta Channel will be getting upgraded to Windows 11, version 24H2 soon. Until that happens, Insiders on Windows 11, version 23H2 in the Beta Channel can choose to upgrade to Windows 11, version 24H2 and this build today if they want.

Changes in Beta Channel builds and updates are documented in two buckets: new features, improvements, and fixes that are being gradually rolled out for Insiders who have turned on the toggle to get the latest updates as they are available (via Settings > Windows Update*) and then new features, improvements, and fixes rolling out to everyone in the Beta Channel. For more information, see the Reminders section at the bottom of this blog post.

New Copilot+ PC experiences

Introducing the new agent in Settings

Last week, we announced a change to Settings designed to help solve one of the most common frustrations we heard: finding and changing settings on your PC. With this update to Settings, you will be able to simply describe what you need help with like, “how to control my PC by voice” or “my mouse pointer is too small” and the agent will recommend the right steps you can take to address the issue. An agent uses AI on your PC to understand your intent and with your permission, automate and execute tasks on your behalf. This experience is rolling out to Windows Insiders on Snapdragon-powered Copilot+ PCs with support for AMD- and Intel™-powered PCs coming soon. Please note that this experience works if your primary display language is set to English.

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Settings > All other settings.

Intelligent text actions in Click to Do for AMD and Intel™-powered Copilot+ PCs

We’re introducing more intelligent text actions to enhance your Click to Do experience even further on AMD and Intel™-powered Copilot+ PCs. Use WIN key + mouse-click or WIN + Q to select a text block and then drag to select the text that you want. You’ll see options to Summarize, Create a bulleted list, or to help you Rewrite your text, so it sounds more causal, more formal, or more polished.

Click to Do leverages the capabilities of Phi Silica, the on-device Small Language Model (SLM) that is built right into Windows. Results from our local model will show directly inline and if you’re happy with the rewrites you can copy them directly to your clipboard for use anywhere.

The intelligent text actions are available when your default language is set to English, at least 10 words are selected, and you’re signed in with either a Microsoft account or Microsoft Entra account. You can learn more about using Click to Do here.

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Desktop Environment > Click to Do.

Changes and Improvements gradually being rolled out to the Beta Channel with toggle on*

[Click to Do (Preview)]

  • ⁠For Windows Insiders using French or Spanish as their primary language on their PC, Click to Do will temporarily only provide Summarize, Create a bulleted list, Refine as intelligent text actions. Rewrite and its options, including Refine, will return in a future update.

[Dynamic Lighting]

  • Dynamic Lighting compatible devices can now be safely removed using the “Safely Remove Hardware and Eject Media” taskbar icon.

[Settings]

  • We’re making it easy to find answers to common questions about your PC and Windows 11 with a dedicated FAQs section on the Settings > System > About page, providing quick and helpful insights for using your PC all in one place. Whether you’re curious about system configuration, performance, or compatibility, this experience ensures you get the information you need for the frequently asked questions for those topics. We hope these FAQs will help you make informed decisions about your PC with ease.

Entra ID support for AI features in Paint and Notepad

We are rolling out Entra ID support for AI features in Paint (version 11.2503.381.0 and higher) and Notepad (version 11.2503.16.0 and higher) to Windows Insiders on IT-managed PCs in the Canary, Dev, and Beta Channels. This update enables commercial customers to access AI features that were previously limited to consumers. In Paint, Entra ID unlocks access to Cocreator, which generates images by combining a sketch and text prompt and Generative Fill, which adds new elements to selected areas of a canvas based on descriptive input. These tools help teams explore ideas visually and speed up creative workflows. In Notepad, Entra ID unlocks the ability to quickly summarize or rewrite text content.

Reminders for Windows Insiders in the Beta Channel

  • Windows Insiders in the Beta Channel on Windows 11, version 24H2 will receive updates based on Windows 11, version 24H2 via an enablement package (Build 26120.xxxx).

  • Updates delivered to the Beta Channel are in a format that offers a preview of enhancements to servicing technology on Windows 11, version 24H2. To learn more, see https://aka.ms/CheckpointCumulativeUpdates.

  • Many features in the Beta Channel are rolled out using Controlled Feature Rollout technology, starting with a subset of Insiders and ramping up over time as we monitor feedback to see how they land before pushing them out to everyone in this channel.

  • For Windows Insiders in the Beta Channel who want to be the first to get features gradually rolled out to you, you can turn ON the toggle to get the latest updates as they are available via Settings > Windows Update*. Over time, we will increase the rollouts of features to everyone with the toggle turned on. Should you keep this toggle off, new features will gradually be rolled out to your PC over time once they are ready.

  • Features and experiences included in these builds may never get released as we try out different concepts and get feedback. Features may change over time, be removed, or replaced and never get released beyond Windows Insiders. Some of these features and experiences could show up in future Windows releases when they’re ready.

  • Some features in active development we preview with Windows Insiders may not be fully localized and localization will happen over time as features are finalized. As you see issues with localization in your language, please report those issues to us via Feedback Hub.

  • Please note that some accessibility features may not work with features like Recall and Click to Do while in preview with Windows Insiders.

  • Because the Dev and Beta Channels represent parallel development paths from our engineers, there may be cases where features and experiences show up in the Beta Channel first.

  • Check out Flight Hub for a complete look at what build is in which Insider channel.
