Windows 11 Insider Preview Build 26120.3964 Brings Exciting New AI Features and Fixes for Beta Users

Microsoft has rolled out Windows 11 Insider Preview Build 26120.3964 (KB5058496) for Beta Channel users, marking a significant update for Windows Insiders on version 24H2. This build includes new features, improvements, and fixes aimed at enhancing the user experience, with notable upgrades like the new Copilot+ PC experiences, intelligent text actions, and expanded AI functionalities.

If you’re a Windows Insider, you’ll soon find yourself equipped with exciting updates that offer improved system performance, greater flexibility in settings, and enhanced capabilities for both work and play. Let’s take a deeper look at what this latest update brings to the table.

Copilot+ PC Experiences: AI-Powered Assistance Right in Settings

One of the standout features of Windows 11 Insider Preview Build 26120.3964 is the enhanced Copilot+ experience, now integrated into the Settings app. Microsoft is addressing one of the most common frustrations among users—the challenge of navigating and finding settings. With this update, Windows Insiders can now describe what they need help with in natural language, and the AI agent will provide step-by-step guidance to help users manage tasks.

For example, you can type "how to control my PC by voice" or "my mouse pointer is too small," and the system will direct you to the right settings to resolve the issue. The AI agent understands your intent and can even automate tasks upon request, streamlining your experience.

How This New Copilot+ Feature Works

To use the new Copilot+ functionality, simply enable the feature on Snapdragon-powered PCs. For AMD and Intel-powered Copilot+ PCs, support will roll out soon. The feature is currently available in English and operates through your primary display language.

What’s Next for Copilot+?

Microsoft plans to expand this AI-powered assistance to more devices and languages as it continues to improve its system. This functionality will make it much easier for users to access complex system features without digging through multiple layers of settings.

Intelligent Text Actions: A Game-Changer for Productivity

Windows 11 Preview Build 26120.3964 also introduces intelligent text actions in the Click to Do feature for AMD and Intel-powered Copilot+ PCs. This upgrade will allow you to highlight text with a simple WIN + mouse-click or WIN + Q, and then select from options to summarize, create a bulleted list, or rewrite the text in a different tone—more casual, formal, or polished.

This feature leverages Phi Silica, an on-device Small Language Model (SLM) that processes your text locally for quick results. The rewritten text can be copied directly to your clipboard for use anywhere, enhancing your workflow and productivity.

Enhancing the Writing Experience

For users looking to refine their writing or generate content quickly, Click to Do’s intelligent text actions will be a highly useful tool. Whether you’re creating content for professional purposes or simplifying complex text, this feature speeds up the process without compromising quality.

Changes to Windows Settings: Easier Access to Important Information

Microsoft is also improving the Settings app, particularly the System > About page. With this update, users will now have access to a dedicated FAQs section that provides quick answers to common questions about system configuration, performance, and compatibility. This section is designed to offer users easy-to-find information to help with troubleshooting or improving their PC experience.

The FAQ section will be a valuable resource for both new and experienced users, ensuring that key information is readily accessible without needing to search through help guides or external sources.

Addressing Previous Bugs and Fixes

Alongside these exciting new features, Microsoft has also rolled out several bug fixes that improve the stability of the system. These updates address issues that many Insiders had reported in previous builds:

Start menu: Crashes affecting Start menu reliability have been fixed.

File Explorer: Resolved deadlock issues when loading File Explorer Home.

Voice Access: Crashes in Voice Access for Spanish users have been addressed.

Taskbar: Fixed keyboard navigation issues in the taskbar.

Windows Spotlight: Resolved problems with the Spotlight flyout getting stuck above other app windows.

These fixes enhance the overall performance and ensure smoother system operations.

Known Issues in Windows 11 Insider Preview Build 26120.3964

As with any beta release, there are still a few known issues that Microsoft is working on:

After performing a PC reset, the build version might show incorrectly as Build 26100 instead of the expected Build 26120.

Xbox controllers may cause issues with Bluetooth connectivity, resulting in a bugcheck.

Recall feature still has certain limitations that users can disable via the “Turn Windows features on or off” option.

Task Manager displays inaccuracies in CPU utility graphs, and system idle process always shows as zero.

Microsoft is actively addressing these known issues, and users can expect fixes in future updates.

Entra ID Support for AI Features in Paint and Notepad

For users on IT-managed PCs, Microsoft is rolling out Entra ID support for AI features in Paint and Notepad. This update is designed for commercial customers and provides access to advanced features previously limited to consumers, including Cocreator in Paint and the ability to rewrite or summarize text in Notepad.

These tools will enhance creative workflows and productivity for teams working on visual or written content, allowing users to combine sketching and text prompts to create images in Paint or quickly rewrite and summarize documents in Notepad.
