Here's the complete list of fixes and improvements:
- [Task Manager (known issue)] Fixed: The count for the number of groups is wrong or always zero (0) on the Processes tab. This occurs when you turn on “Group by type.”
- [Windows Subsystem for Linux (WSL)] Fixed: You cannot access your Dev Drive.
- [Internet connection] Fixed: A few devices cannot connect to the internet. This occurs when a DHCP server response has duplicate DHCP options. This stops IPv4 connections on certain networks.
- [Notifications] New! You can now stop the suggestions to turn off notifications from certain apps. Select the ellipses (…) in the notification and turn it off. You can also go to Settings > System > Notifications and turn it off. Look for “Notification Suggestions” in the senders list. An entry will only appear in the list after you receive a notification.
- [Wi-Fi password dialog] New! The dialog now has the Windows 11 visual design. Go to Settings > Network & internet.
- [Narrator]
- New! This update adds a new Narrator shortcut. Press the Narrator key + Ctrl + X to copy what the Narrator last spoke to the clipboard. This shortcut is useful when you want to quickly copy some content, like codes or numbers for use.
- New! It will now auto-read the contents of an email message in the new Outlook. This is like the behaviour in Outlook Classic.
- [Start menu] New! “All apps” has the new name, “All.”
- [ALT + Tab] Fixed: When switching between certain windows, the screen goes black on some PCs for a few seconds.
- [Scanning apps] Fixed: They don't detect certain scanners, although they are connected.
- [Web sign-in] Fixed: You cannot sign in to your account from the web because the screen stops responding.
- [Copilot key settings] New! You can configure the Copilot key on the keyboard. On new devices, the key opens the Copilot app. If you sign in to your account using a Microsoft Entra ID, the key opens the Microsoft 365 app. You can make the key open a different app or open Search. To do this, go to Settings > Personalization > Text input. To make the key open a different app, the app must be in a signed MSIX package. This ensures that the app meets security and privacy standards to keep you safe. If your PC’s keyboard does not have a Copilot key, changing this setting will do nothing.
- [WindowsDisk Cleanup app] Fixed: This update addresses some of the causes for the wrong free space estimates and improves its accuracy.
- [Notifications] New! You can now stop the suggestions to turn off notifications from certain apps. Select the ellipses (…) in the notification and turn it off. You can also go to Settings > System > Notifications and turn it off. Look for “Notification Suggestions” in the senders list. An entry will only appear in the list after you receive a notification.

- [Battery use] Fixed: A device uses too much battery power in Modern Standby.
- [Microsoft Teams] Fixed: The issue stops you from joining Teams meetings when you select an Outlook meeting reminder.
- [Product activation phone numbers] Fixed: This adds new phone numbers for several regions.
- [Multi-Function Printer (MFP)] Fixed: When you use a USB cable to connect to it, it prints specific network command text when you do want it to.
