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.
Fixes gradually being rolled out to the Beta Channel with toggle on*
[Start menu]
- Fixed a few crashes impacting Start menu reliability for Insiders in recent flights.
[File Explorer]
- Fixed a deadlock which could occur when loading File Explorer Home, causing it to hang.
- Fixed an issue where Shared by and Activity information was missing in the tooltip when hovering over recent documents in File Explorer Home.
- Fixed an issue which could cause explorer.exe to crash when closing File Explorer.
[Voice Access]
- Fixed an issue which was causing voice access crashes when using Spanish.
[Taskbar]
- Fixed an issue where when using Tab and Shift + Tab to move keyboard focus around the taskbar, if you went backwards at least once you could get keyboard focus stuck on the taskbar frame, which would potentially lead screen readers to just say “pane”.
- Fixed an issue which could cause the media controls in the preview windows for apps in the taskbar (that support it) to flicker.
[Windows Spotlight]
- Fixed an issue where the Windows Spotlight flyout for “learn more about this picture” (when using it as your desktop background) might get stuck above other app windows.
[Live captions]
- Fixed an issue causing live captions to crash in the previous build.
[Other]
- Improved the colors used in MMC when items are selected, both generally, and when contrast modes are enabled.
- Fixed an underlying issue which could make some apps like Word hang when trying to print.
Known issues
[General]
- After you do a PC reset under Settings > System > Recovery, your build version may incorrectly show as Build 26100 instead of Build 26120. This will not prevent you from getting future Beta Channel updates, which will resolve this issue.
- We’re working on the fix for an issue where core Windows surfaces are not able to load in safe mode (File Explorer, Start menu, and others) after the previous flight.
- [NEW] The option to reset your PC under Settings > System > Recovery will not work on this build.
[Xbox Controllers]
- Some Insiders are experiencing an issue where using their Xbox Controller via Bluetooth is causing their PC to bugcheck. Here is how to resolve the issue. Open Device Manager by searching for it via the search box on your taskbar. Once Device Manager is open, click on “View” and then “Devices by Driver”. Find the driver named “oemXXX.inf (XboxGameControllerDriver.inf)” where the “XXX” will be a specific number on your PC. Right-click on that driver and click “Uninstall”.
[Recall (Preview)]
- [REMINDER] You are always in control and can always choose to remove Recall anytime via “Turn Windows features on or off”. Removing Recall will delete entry points and binaries. Like any feature, Windows sometimes keeps temporary copies of binaries for serviceability. These Recall binaries are not executable and are eventually removed over time.
- [REMINDER] Make sure you update Microsoft 365 apps to the latest version so you can jump back into specific documents.
[Click to Do (Preview)]
- [REMINDER] The intelligent text actions are now locally moderated to ensure the safety of prompts and responses and has replaced the cloud endpoint. Now that these intelligent text actions are fully local, they are also available in Click to Do in Recall.
- [REMINDER] If any of your actions on image entities are no longer appearing, please ensure you have the latest updates for the Photos and Paint app from the Microsoft Store.
The following known issues will be fixed in future updates to Windows Insiders:
- [NEW] Image actions may not show up in Click to Do.
- [NEW] Windows Insiders on AMD or Intel™-powered Copilot+ PCs may experience long wait times on the first attempt to perform intelligent text actions in Click to Do after a new build or model update.
[Improved Windows Search]
- [REMINDER] For improved Windows Search on Copilot+ PCs, it is recommended that you plug in your Copilot+ PC for the initial search indexing to get completed. You can check your search indexing status under Settings > Privacy & security > Searching Windows.
[Start menu]
- We’re investigating reports that clicking your profile picture isn’t opening the Account Manager for some Insiders after the last flight.
[Task Manager]
- After adding the new CPU Utility column, you may notice that System Idle Process always shows as 0.
- The CPU graphs in the Performance page are still using the old CPU utility calculations.
[Narrator]
- [NEW] We are investigating an issue where the richer image descriptions on your Copilot+ PC with Narrator do not work.
[Voice Access]
- [NEW] We are investigating an issue where support for more descriptive and flexible language on Copilot+ PCs does not work as expected.
