11/12/24
IMPORTANT
Because of minimal operations during the Western holidays and the upcoming new year, there won’t be a non-security preview release for the month of December 2024. There will be a monthly security release for December 2024. Normal monthly servicing for both security and non-security preview releases will resume in January 2025.


For information about Windows update terminology, see the article about the types of Windows updates and the monthly quality update types. For an overview of Windows 11, version 24H2, see its update history page.

Note Follow @WindowsUpdate to find out when new content is published to the Windows release health dashboard.

Important: Windows updates do not install Microsoft Store application updates. If you are an enterprise user, see Microsoft Store apps - Configuration Manager. If you are a consumer user, see Get updates for apps and games in Microsoft Store.

Tip: See the release notes for Windows Server 2025.

Windows 11 servicing stack update (KB5049685)- 26100.2592​

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

Applies toSymptomWorkaround
All usersWe’re aware of an issue where players on Arm devices are unable to download and play Roblox via the Microsoft Store on Windows.Players on Arm devices can play Roblox by downloading the title directly from www.Roblox.com.
All usersFollowing the installation of the October 2024 security update, some customers report that the OpenSSH (Open Secure Shell) service fails to start, preventing SSH connections. The service fails with no detailed logging, and manual intervention is required to run the sshd.exe process.

This issue is affecting both enterprise, IOT, and education customers, with a limited number of devices impacted. Microsoft is investigating whether consumer customers using Home or Pro editions of Windows are affected.
Customers can temporarily resolve the issue by updating permissions (ACLs) on the affected directories. Follow these steps:
  1. Open PowerShell as an Administrator.
  2. Update the permissions for C:\ProgramData\ssh and C:\ProgramData\ssh\logs to allow full control for SYSTEM and the Administrators group, while allowing read access for Authenticated Users. You can restrict read access to specific users or groups by modifying the permissions string if needed.

    Use the following commands to update the permissions:

    $directoryPath = "C:\ProgramData\ssh" $acl = Get-Acl -Path $directoryPath $sddlString = "O:BAD:PAI(A;OICI;FA;;;SY)(A;OICI;FA;;;BA)(A;OICI;0x1200a9;;;AU)" $securityDescriptor = New-Object System.Security.AccessControl.RawSecurityDescriptor $sddlString $acl.SetSecurityDescriptorSddlForm($securityDescriptor.GetSddlForm("All")) Set-Acl -Path $directoryPath -AclObject $acl
  3. Repeat the above steps for C:\ProgramData\ssh\logs.

Microsoft is actively investigating the issue and will provide a resolution in an upcoming Windows update. Further communications will be provided when a resolution or additional workarounds are available.

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.

Install this update

To install this update, use one of the following Windows and Microsoft release channels.

AvailableNext Step
Yes (Windows Update)None. This update will be downloaded and installed automatically from Windows Update and Microsoft Update.
Yes (MSU)Before you install this update

To get the standalone package(s) for this update, go to the Microsoft Update Catalog website. This KB contains one or more MSU files that must be installed in order.


Install this update

Method 1: Install all MSU files together

Download all MSU files for KB5048667 from Microsoft Update Catalog and place them in the same folder (for example, C:/Packages). Use Deployment Image Servicing and Management (DISM.exe) to install the target update. DISM will use the folder specified in PackagePath to discover and install one or more prerequisite MSU files as needed.


Updating Windows PC
To apply this update to a running Windows PC, run the following command from an elevated Command Prompt:


DISM /Online /Add-Package /PackagePath:c:\packages\Windows11.0-KB

Or, run the following command from an elevated Windows PowerShell prompt:
Add-WindowsPackage -Online -PackagePath "c:\packages\Windows11.0-KB

Updating Windows Installation media
To apply this update to Windows Installation media, see Update Windows installation media with Dynamic Update.


To add this update to a mounted image, run the following command from an elevated Command Prompt:

DISM /Image:mountdir /Add-Package /PackagePath:Windows11.0-KB

Or, run the following command from an elevated Windows PowerShell prompt:

Add-WindowsPackage -Path "c:\offline" -PackagePath "Windows11.0-KB

Method 2: Install each MSU file individually, in order

Download and install each MSU file individually either using DISM or Windows Update Standalone Installer in the following order:
  1. windows11.0-kb5043080-x64_953449672073f8fb99badb4cc6d5d7849b9c83e8.msu
  2. windows11.0-kb5048667-x64_d4ad0ca69de9a02bc356757581e0e0d6960c9f93.msu

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.

For a list of the files that are provided in the servicing stack update, download the file information for the SSU (KB5049685) - version 26100.2592 .

Okay yea i am a bit scared to delete something heavy system related.
i have issues with Desktop background spotlight images, and they are saved under a folder called iris at MicrosoftWindows.Client.CBS_cw5n1h2txyewy
so, i just guessed that deleting settings and roaming inside the MicrosoftWindows.Client.CBS_cw5n1h2txyewy
might fix it, but it seems more stuff is depended on those settings and roaming files i think :P

Check this out to see if it helps.

What is it with Microsoft?
I got a notification this KB was available (Jan 12, 2025) so I tried downloading it - stuck at 2%.
Paused, tried again - nope, now 0% and fails every time.
Now it errors every time. It's not on the Microsoft catalog, except for the early Dec 2024 version.

Looks like a few people are having the same issue:
Link

I would have thought this would be installed already.
Could it be part of a prior rollup and not showing as a separate KB?
Is there a way to show all KB's installed, separate and part of rollup?
Back to the Update Catalog - KB5048667 also says I should also get KB5043080, again not on my update history.
Ok - I ran the KB5043080 and it said not applicable, and KB5048667 said already installed.
...and others having the exact same problem...
Groan...

Do not try to understand Microsoft. You might be subject to severe headaches, dizziness, confusion and a profound desire to start using a pen and paper and start drawing your own pictures with coloured crayons.
