After that, you must sign in using a Microsoft account (MSA) or a Microsoft Entra ID account (formerly Azure Active Directory (Azure AD)). To sign in, use the link in the dialog that appears in Copilot in Windows. If you do not sign in, some Copilot features might not work. To learn more, see Welcome to Copilot in Windows and Manage Copilot in Windows.

• New! This update adds more content to your lock screen. Sports, traffic, and finance content will appear along with weather. To turn on this feature, go to Settings > Personalization > Lockscreen.

  Note This feature might not be available to all users because it will roll out gradually.

• New! You can now use voice access with the following languages:

  • French (France, Canada)

  • German

  • Spanish (Spain, Mexico)

    When you turn on voice access for the first time, Windows will ask you to download a speech model. You might not find a speech model that matches your display language. You can still use voice access in English (US). You can always choose a different language from Settings > Language on the voice access bar.

• New! You can now use all voice access features on multiple displays. These include number and grid overlays that, in the past, you could only use on the primary display. While you are using the grid overlay on a screen, you can quickly switch to another display. To do that, use the alphabet or NATO phonetic in your command. For example, “B” or “Bravo” are both valid for the display that is assigned that letter.

  You can also use the “mouse grid” command to quickly move your mouse to a specific point on a display. For example, in the screenshot below, the command will be, “mouse grid A 114.” Finally, you can use the drag and drop feature to move files, apps, and documents from one display to another.

• New! This update introducesvoice shortcuts or custom commands. You can use them to create your own commands in the supported English dialects. To start, say “what can I say” and click the “Voice shortcuts” tab on the left panel. You can also use the command “show voice shortcuts” to open the Voice shortcuts page. Click Create new shortcut. Use your voice or other input to create a command. Give it a name and select one or more actions. After you fill in the necessary information, click Create. Your command is now ready to use. To view all the voice shortcuts you have created, go to the command help page or use the voice command, “show voice shortcuts.”

• New! You can now listen to a preview of the ten natural voices before you download them. See the Narrator section of the September 2023 update for the list. These voices use modern, on-device text-to-speech. Once you download them, they work without an internet connection. However, to listen to a preview, you need an internet connection. To add and use one of the natural voices, follow the steps below.

1. To open Narrator settings, press the WIN+CTRL+N hotkey.

2. Under Narrator’s voice, select Add, which is next to Add natural voices.

5. If you like the preview, click Download and Install. The new voice downloads and is ready for use in a few minutes, depending on your internet download speed.

6. In Narrator settings, select your preferred voice from the menu in Narrator’s voice > Choose a voice.

For example, you can tell it to, “speak faster,” “read next line,” and so on. To get started, search for “voice access” in Windows search and set it up.

• New! This update changes the apps that appear in the Windows share window. The account you use to sign in affects the apps that are in “Share using.” For example, if you use a Microsoft account (MSA) to sign in, you will see Microsoft Teams (free). When you use a Microsoft Entra ID account (formerly Azure Active Directory) to sign in, your Microsoft Teams (work or school) contacts show instead.
