Windows 11 servicing stack update (KB5063707) - 22621.5619 and 22631.5619

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. To learn more about SSUs, see Simplifying on-premises deployment of servicing stack updates.

Known issues in this update​​​​​​​

Symptoms

Following installation of this update, there might be issues when using the Microsoft Changjie IME (input method editor) for Traditional Chinese. Reported symptoms include:

  • Inability to form or select words after typing the full composition (associate phrase window).

  • Spacebar or blank key not responding.

  • Incorrect or distorted word outputs.

  • The conversion candidate window fails to display properly.

Workaround Windows IME supports a compatibility setting that enables the use of a previous version of an IME instead. Employing this option should help resolve this issue. To revert to the old version of the Microsoft Changjie IME, follow the steps at Revert to a previous version of an input method editor (IME).  Microsoft is working on releasing a solution and will provide more information when it is available.

Included

This update downloads and installs automatically from Windows Update and Microsoft Update.

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.
