Windows 10 servicing stack update - 19045.4106

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.

Symptom

Workaround

Windows devices using more than one (1) monitor might experience issues with desktop icons moving unexpectedly between monitors or other icon alignment issues when attempting to use Copilot in Windows (in preview).

To prevent users from encountering this issue, Copilot in Windows (in preview) might not be available on devices that have been used or are currently being used in a multimonitor configuration.

We are working on a resolution and will provide an update in an upcoming release.

Copilot in Windows (in preview) is not currently supported when your taskbar is located vertically on the right or left of your screen.

To access Copilot in Windows, make sure your taskbar is positioned horizontally on the top or bottom of your screen.

We are working on a resolution and will provide an update in an upcoming release.

After you install KB5034203 (dated 01/23/2024) or later updates, some Windows devices that use the DHCP Option 235 to discover Microsoft Connected Cache (MCC) nodes in their network might be unable to use those nodes. Instead, these Windows devices will download updates and apps from the public internet. IT administrators also see increased download traffic on their internet routes.

Those of you who use the Home edition of Windows are not likely to experience this issue. MCC and DHCP Option 235 are typically used in enterprise environments.

Option 1: Configure Microsoft Connected Cache endpoint in DOCacheHost policy as indicated in Cache hostname. Additionally, DOCacheHostSourcehas to be set to 1or removed as indicated in Cache hostname source. By default, the DOCacheHost and DOCacheHostSource policies have no value.

Option 2: You can mitigate this issue using Group Policies available through our support channel. Organizations can request help at Support for business.

We are working on a resolution and will provide an update in an upcoming release.

How to get this update

Before installing this update

Microsoft now 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.

Prerequisite:

Based on your installation scenario, choose one of the following:

  1. For offline OS image servicing:

    If your image does not have the March 22, 2022 (KB5011543) or later LCU, you must install the special standalone May 10, 2022 SSU (KB5014032) before installing this update.

  2. For Windows Server Update Services (WSUS) deployment or when installing the standalone package from Microsoft Update Catalog: 

    If your devices do not have the May 11, 2021 (KB5003173) or later LCU, you must install the special standalone August 10, 2021 SSU (KB5005260) before installing this 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.
