Highlights 

Note: Below is a summary of the key issues that this update addresses when you install this KB. If there are new features, it lists them as well. The bold text within the brackets indicates the item or area of the change we are documenting.

These might not be available to all users because they will roll out gradually.

  • ​​​​​​​[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 from there. Look for “Notification Suggestions” in the senders list. An entry will only appear in the list after you receive a notification.

  • [Start menu]​​​​​​​ New! “All apps” has the new name, “All.”

  • [Narrator]

    • New! This update adds a new Narrator shortcut. Press the Narrator key + Ctrl + X to copy what 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 behavior in Outlook classic. 

  • [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 M365 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.

  • [Battery use] Fixed: A device uses too much battery power while the device is 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.

  • [vmswitch] Fixed: A vmswitch triggers a stop error. This occurs when you use Load Balancing and Failover (LBFO) teaming with two virtual switches on a virtual machine (VM). In this case, one virtual switch uses single root Input/Output virtualization (SR-IOV).

  • [Collector sets] Fixed: They do not close properly when an exception occurs during startup or while the set is active. Because of this, the command to stop a collector set stops responding.

  • [Country and Operator Settings Asset (COSA)] Fixed: This update brings profiles up to date for certain mobile operators.

  • [Windows Hello for Business] Fixed: PIN reset does not work when you select the “I forgot my PIN’ link on the credentials screen.

  • [WebView2 apps] Fixed: They do not detect input from Xbox 360 and Bluetooth controllers.

  • [Bluetooth] Fixed: An app stops responding because of a memory leak in a device.

Windows 11 servicing stack update (KB5044620) - 22621.4383 and 22631.4383

This update makes quality improvements to the servicing stack, which is the component that installs Windows updates. Servicing stack updates (SSU) ensure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates. 

Known issues in this update

Microsoft is not currently aware of any issues with this update.

How to get this update

Before you install this update

Microsoft combines the latest servicing stack update (SSU) for your operating system with the latest cumulative update (LCU). For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

If you want to remove the LCU

To remove the LCU after installing the combined SSU and LCU package, use the DISM/Remove-Package command line option with the LCU package name as the argument. You can find the package name by using this command: DISM /online /get-packages.

Running Windows Update Standalone Installer (wusa.exe) with the /uninstall switch on the combined package will not work because the combined package contains the SSU. You cannot remove the SSU from the system after installation.
