Announcements and messages​

This section provides key notifications related to this release, including announcements, change logs, and end-of-support notices.

Simplified Windows update titles​

A new, standardized title format makes Windows updates easier to read and understand. It improves clarity by removing unnecessary technical elements like platform architecture. Key identifiers such as date prefixes, the KB number, and build or version are retained to help you quickly recognize each update.

For more details, see Simplified Windows Update titles or its accompanying blog post.

December servicing update schedule​

Due to reduced operations during the Western holidays in December and New Year's Day, Microsoft will not release a non-security preview update in December 2025. The monthly security update will still be available as scheduled. Regular monthly servicing, including both security updates and non-security preview updates, will resume in January 2026.

Windows Secure Boot certificate expiration​

Important: Secure Boot certificates used by most Windows devices are set to expire starting in June 2026. This might affect the ability of certain personal and business devices to boot securely if not updated in time. To avoid disruption, we recommend reviewing the guidance and taking action to update certificates in advance. For details and preparation steps, see Windows Secure Boot certificate expiration and CA updates.

A gradual rollout delivers an update in phases, so features reach devices over time instead of all at once, meaning availability varies by device. A normal rollout is the broad release to all eligible devices at the same time, usually when it reaches general availability (GA).

Gradual rollout

This issue is addressed in KB5072033.

2 Password icon might be missing or invisible in the lock screen sign-in options

Symptoms

After installing the August 2025 non-security preview update (KB5064081) or later updates, you might notice that the password icon is not visible in the sign-in options on the lock screen. If you hover over the space where the icon should appear, you’ll see that the password button is still available. Select this placeholder to open the password text box and enter your password. After entering your password, you can sign in normally.

Individuals using Windows Home or Pro editions on personal devices are very unlikely to experience this issue. This issue primarily affects enterprise or managed IT environments.

Workaround

This issue is mitigated using Known Issue Rollback (KIR).

For enterprise-managed devices managed by IT departments that have installed the affected update and encountered this issue, IT administrators can resolve it by installing and configuring the Group policy listed below. The special Group Policy can be found in Computer Configuration > Administrative Templates > <Group Policy name listed below>.

For information on deploying and configuring these special Group Policy, please see How to use Group Policy to deploy a Known Issue Rollback.

Group Policy downloads with Group Policy name:
Important: You will need to install and configure the Group Policy for your version of Windows to resolve this issue. You will also need to restart your device(s) to apply the group policy setting. Note that the Group Policy will temporarily disable the change causing this issue.

We are working on a resolution in a future Windows update and will provide more information when it is available.

3 Mirror networking on Windows Subsystem for Linux might fail

Symptoms

After installing the October 2025 Windows non-security update (KB5067036), released on October 28, 2025, or a later update, mirrored networking mode in Windows Subsystem for Linux (WSL) might cause issues with some third-party VPNs. When this issue occurs, you might see a “No route to host” error, even though the Windows host can still access the same destinations. As a result, you might be unable to access corporate resources over VPN and experience failures with VPN-dependent services.

This issue happens because the VPN application's virtual interface doesn’t respond to ARP (Address Resolution Protocol) requests. Reports indicate that Cisco Secure Client (formerly Cisco AnyConnect) and OpenVPN are affected.

Note: Home users of Windows Home or Pro editions are unlikely to experience this issue. It primarily affects connectivity to enterprise resources over VPN, including DirectAccess.

Workaround

This issue is addressed in KB5074109.

4 RemoteApp sessions might fail to start on Azure Virtual Desktop

Symptoms

Note: Individuals using Windows Home or Pro editions on personal devices are very unlikely to experience this issue as Azure Virtual Desktop (AVD) is more commonly used in enterprise environments.

After installing the November 2025 Windows non-security update (KB5070311) or later updates, you might experience RemoteApp connection failures in Azure Virtual Desktop (AVD) environments. Full desktop sessions aren’t affected.

Workaround

This issue is addressed in KB5074109.

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
Included
Open Start > Settings Update & Security > Windows Update. In the Optional updates available area, you will find the link to download and install available updates.
Check for optional updates
Yes 4Before 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 require installation in a specific order.

Install this update

Method 1: Install all MSU files together
Download all MSU files for KB5070311 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-KB5070311-x64.msu

Or, run the following command from an elevated Windows PowerShell prompt:
Add-WindowsPackage -Online -PackagePath "c:\packages\Windows11.0-KB5070311-x64.msu"

Or use Windows Update Standalone Installer to install the target update.

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

Note: When downloading other Dynamic Update packages, ensure they match the same month as this KB. If the SafeOS Dynamic Update or Setup Dynamic Update is not available for the same month as this KB, use the most recently published version of each.

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-KB5070311-x64.msu

Or, run the following command from an elevated Windows PowerShell prompt:
Add-WindowsPackage -Path "c:\offline" -PackagePath "Windows11.0-KB5070311-x64.msu" -PreventPending

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-kb5070311-x64_199ed7806a74fe78e3b0ef4f2073760000f71972.msu

4 This latest cumulative update includes updates for AI components. Even though the AI component updates are included in the update, the AI components are only applicable to Windows Copilot+ PCs and will not install on Windows PC or Windows Server.

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.

File information

For a list of the files provided in this update, download the file information for cumulative update 5070311.

For a list of the files provided in the servicing stack update, download the file information for the SSU (KB5071142) - version 26100.7295.

Not here, I see it also on Dev 26220.7271, but not on Canary.

With 28000.1199 in Dark mode, I see it flashing a black empty window not white. 🤷‍♂️
Checked the same behavior on 2 machines.

Same machines and same hardware show the problem Explorer white flash with Builds 26200.7309 and 26220.7271. 🤷‍♂️

Yes, it opens an empty window briefly before it is populated, it happens with Light and Dark mode.
It is most noticeable when using Dark mode because the empty window flashes white instead of black as it should.
Verified on several machines with this Build.
Not bothering me, I can wait for a fix. 😉

I wonder if my not seeing it has anything to do with my using an OLED screen.

The technical difference is that OLED screens are self‑emissive (each pixel generates its own light), while IPS screens are LCD panels that require a backlight.

The technical difference is that OLED screens are self‑emissive (each pixel generates its own light), while IPS screens are LCD panels that require a backlight.

That does not explain the different behavior with File explorer flashing a white empty window.
Perhaps it is a timing issue with the duration of the initial empty file explorer window that makes it unnoticeable. 😎🤷‍♂️

I think you're right about it's being a timing issue. OLED pixels switch almost instantly, reducing ghosting in fast motion (gaming, video editing). IPS has slower liquid crystal transitions.
