Improving discoverability of screen casting in Windows 11

Casting from your Windows PC allows you to wirelessly extend your display to another nearby PC, TV or other external displays. After trying some improvements to this experience out with Windows Insiders in the Dev Channel with Build 23516, we’re making some additional refinement to those improvements that focus on educating users about the Cast feature and improving its discoverability in Windows 11. Those improvements include:

  • When doing multitasking activities on your PC such as often switching between windows to complete a task or using Snap Assist to organize your screen space, we will provide the suggestion to Cast via a notification toast.
  • We have updated the Cast flyout in Quick Settings with additional support for you in case you face any trouble discovering nearby displays, fixing connections, and more.

Cast flyout in Quick Settings now shows link for troubleshooting device discovery and other casting issues.

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Display and Graphics > Wireless Display and Casting.

New widgets board settings

We’ve updated the widget settings experience, providing more ways for users to customize their widgets board experience. One of the new settings enables you to just show widgets on your widgets board and another makes it easier for you to discover how to personalize your feed content.

New widgets board settings.

The new settings experience also allows you to select the account you want to use for your Microsoft Start powered widgets and feeds. This means you are no longer limited to using the account you used to sign into Windows to drive those experiences, just like your other app powered widgets. You can easily manage the account used by Microsoft Start by navigating to ‘Microsoft Start’ settings under the ‘Personalize your content’ section in your widgets board settings. This change allows you to further personalize the experience to your preferences. The new settings experience is not limited by region.

[We are beginning to roll this out to Windows Insiders in the Canary, Dev, and Beta Channels this week, so the experience isn’t available to all Insiders just yet as we plan to monitor feedback before pushing it out to everyone.]

Changes and Improvements


  • Starting early next week, Windows Insiders in the Dev Channel on Build 23601 will be prompted to reboot to install Windows Configuration Update (KB1234567). Windows Configuration Updates are what we use to new features via Controlled Feature Rollout (CFR) technology. Windows Configuration Update (KB1234567) does not enable any new features as we’re testing the delivery of these updates via our servicing pipeline, and the reboot prompt to install them. After rebooting to install this update, it will be listed under “Other Updates” under Settings > Windows Update > Update History.

[Copilot in Windows]*

  • We are trying out the ability to “undock” Copilot in Windows with Windows Insiders. Just click the new icon to unpin the Copilot panel at the top right in the header. While undocked, Copilot can appear above or below other apps in Windows while maintaining its fixed position on the desktop. This allows users to access Copilot while minimizing disruption to other user activities. Additionally, can resize the Copilot window for a more comfortable experience. Simply click-and-drag the edge of the Copilot window to adjust the width to your needs.

  • We are trying out a change where when swiping from the right edge of the desktop on a touch display will open Copilot instead of notifications.

[Windows Share]

  • The Windows share window now supports sharing with WhatsApp under the “Share using” section. If you don’t have WhatsApp installed, you can choose to install it from Windows share window directly. Over time, we plan to try this experience out with other apps as well.

[Nearby Sharing]

  • We are introducing the ability to quickly give your device a more friendly name to identify sharing to and from with nearby share under Settings > System > Nearby sharing. This change originally began rolling out with Build 23545, but we are re-rolling it out with improvements to the experience. Let us know what you think.

  • Narrator users can now use voice access to open applications, dictate text and interact with elements on the screen using their voice. Narrator users can use voice access to give Narrator commands using their voice . For e.g., “speak faster”, “read next line”, etc. To get started, search for “voice access” in Windows search and set it up.


[Copilot in Windows]*

  • Fixed an issue that was causing full screen apps to minimize on secondary monitors when launching Copilot.

[Start menu]

  • Fixed an issue causing the Recommended section to appear blank for some Insiders.

[File Explorer]

  • Fixed an issue impacting explorer.exe reliability.


  • Fixed an issue where uncombined taskbar icons were cutting off the title instead of adjusting with the title length.

[Task Manager]

  • When creating a dump file for a process, the dump file location should be selectable now, so you can copy it out.


  • Fixed an issue where if you go to System > Nearby Sharing it was crashing Settings.

NOTE: Some fixes noted here in Insider Preview builds from the Dev Channel may make their way into the servicing updates for the released version of Windows 11.

Known issues

[Copilot in Windows]*

  • When first launching or after refreshing Copilot in Windows while using voice access, you’ll need to use “Show grid” commands to click in the “Ask me anything” box for the first time.


  • [NEW] The Microsoft 365, Outlook Calendar, and To Do widgets get stuck in an error state when the Microsoft Start feed is disabled. FIXED as of 12/8.
