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.


To learn more about Windows update terminology, see types of Windows updates and monthly quality update types. For an overview, see the update history page for Windows 11, version 24H2 and version 25H2.

Change Log

Change date​
Change description​
October 22, 2025
October 19, 2025
  • Added the following new improvement included in this update:

    [Cryptography] This update enforces a security hardening improvement by requiring use of Key Storage Provider (KSP) instead of Cryptographic Service Provider {CSP) for RSA-based smart card certificates. If you experience problems with smart card authentication as a result of this design change, see the Windows Release Health site for resolution steps. For additional details, see CVE-2024-30098.

Highlights

  • This update addresses security issues for your Windows operating system.

Improvements

This security update contains fixes and quality improvements from KB5065789 (released September 29, 2025). The following summary outlines key issues addressed by this update. Also, included are available new features. The bold text within the brackets indicates the item or area of the change.
  • [Browser] Fixed: This update addresses an issue that caused the print preview screen to stop responding in Chromium-based browsers.
  • [Gaming] Fixed: An issue occurred when users signed in to a Windows device using only a Gamepad at the lock screen. If no other input methods—such as touch or fingerprint—were used during sign-in, apps and games did not respond to input afterward.
  • [PowerShell]
    • Fixed: This update addresses an issue that affects PowerShell Remoting and Windows Remote Management (WinRM), where commands might time out after 10 minutes.
    • Fixed: This update addresses an issue that prevented an audit event from being logged.
  • [Windows Hello] Fixed: This update addresses an issue that affects the setup process for Windows Hello face recognition when using USB infrared camera modules. Users were unable to complete setup due to a persistent error message, such as “Make sure your face is centered in the frame.”
  • [Compatibility] This update removes the ltmdm64.sys driver. Fax modem hardware dependent on this specific driver will no longer work in Windows.
  • [Cryptography] This update enforces a security hardening improvement by requiring use of Key Storage Provider (KSP) instead of Cryptographic Service Provider {CSP) for RSA-based smart card certificates. If you experience problems with smart card authentication as a result of this design change, see the Windows Release Health site for resolution steps. For additional details, see CVE-2024-30098.
  • [File Explorer] After installing this update, File Explorer automatically disables the preview feature for files downloaded from the internet. This change is designed to enhance security by preventing a vulnerability when users preview potentially unsafe files. For details, including steps to unblock files, see File Explorer automatically disables the preview feature for files downloaded from the internet.
If you've already installed previous updates, your device will download and install only the new updates included in this package.

For more information about security vulnerabilities, see the Security Update Guide website and the October 2025 Security Updates.

Windows 11 servicing stack update (KB5067360)- 26100.6893

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

1 Problems playing protected content in some BluRay/DVD/Digital TV apps

Symptoms
Some Digital TV and Blu-ray/DVD apps might not play protected content as expected after installing the August 29, 2025, Windows non-security preview update (KB5064081), or later updates.

Apps that use Enhanced Video Renderer with HDCP enforcement or Digital Rights Management (DRM) for digital audio might show copyright protection errors, frequent playback interruptions, unexpected stops, or black screens.

Streaming services are not affected.

Workaround
This issue is partially resolved. Problems affecting certain applications that use Enhanced Video Renderer with HDCP enforcement have been addressed in the September 2025 Windows preview update (KB5065789) and later updates.

We recommend installing the latest update for your device. It includes important improvements and fixes, including a resolution for this issue.

However, some apps that use DRM for digital audio might still experience problems.

We’re investigating a long-term solution for affected apps and will share more information when it's available.

2 USB mouse and keyboard not working in the Windows Recovery Environment

Symptoms
After installing October 2025 security update (KB5066835), USB devices, such as keyboards and mice, do not function in the Windows Recovery Environment (WinRE). This issue prevents navigation of any of the recovery options within WinRE. Note that the USB keyboard and mouse continue to work normally within the Windows operating system.

Workaround
This issue is addressed in KB5070773.

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
This update downloads and installs automatically from Windows Update and Microsoft Update.
Yes 1Before 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 KB5066835 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-KB5066835-x64.msu

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

Add-WindowsPackage -Online -PackagePath "c:\packages\Windows11.0-KB5066835-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-KB5066835-x64.msu

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

Add-WindowsPackage -Path "c:\offline" -PackagePath "Windows11.0-KB5066835-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-kb5066835-x64_199ed7806a74fe78e3b0ef4f2073760000f71972.msu

1 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 5066835.

For a list of the files provided in the servicing stack update, download the file information for the SSU (KB5067360) - version 26100.6893.

What actually happened is that it slogged away for a solid hour, then announced that something had gone wrong
Sounds like symptoms of drive failure. Prepare to back up and replace the SSD.

I think they just mean you'll be able to chat with copilot outloud ? :LOL: And copilot will use the webcam at the same time maybe.
Could be, to be honest I don't use AI for anything except occasional searches and I have two AI machines one of which has a full co-pilot NPU lol. I'm curious what the big announcement will be though lol.

I'm usually not interested in AI, at least not the AI that I see some other people into. I generally build gaming/simulation workstations.

10 laptops in the house. Installed OK on 8, but got the 0x800f0983 error on 2 laptops, both at 100% installation (before reboot offered) & then flicked to retry. Two retries and no luck. Based on posts here decided to run "Fix Windows using Windows Update" in recovery. Worked, taking the laptop to .6899, but like someone else said above, that was the SLOWEST repair ever. Took 3.5hrs with excellent internet speed. Usually <1/2 that time. Just running repair on the other one now.

Interestingly, one of the two affected machines, is the same exact machine (HP spectre 13 2019) as one that installed with no issues. Both machines are set up IDENTICALLY in terms of software & all settings. Bizarre. The other machine that it failed on is an HP Envy 15.

All 10 had a sfc followed by DISM scanhealth the evening before updating, with no store corruption found.

EDIT: Second repair installation going much more quickly than the one I did last night. Is up to 64% at 30mins mark.

Windows updates have become a worrisome adventure anymore not knowing which way your update will go. Got lucky this one but I'm already worried how the next one will go lol.

I only ever had one update fail. For me, it was after I got the reclaimable packages down to zero.
And on Windows 10, I couldn't upgrade from 1909 to 2004.

In both cases, the good old In-Place Upgrade came to the rescue. :-)

    Still assembled, still runs. Haven't turned it on for 15 years?
Just a heads up: Microsoft has teased that a big announcement about Windows is happening on Thursday, and has hinted that the news will be related to how people use and interact with the OS.

Imagine if you are in an open plan office, and everybody is talking, shouting, swearing at their pcs. The noise level could become intolerable.

Any self respecting corporation would disable this nonsense immediate via Group Policy LOL.

The simplest description of this mode of operation is "A solution to a problem we do not have!".

I accept for some people with disabilities, this could be a useful feature BUT it is a two edged sword. Deaf people could find the additional noise in an open plan office drowning peoples speech (I have difficulty hearing people in noisy pubs).

I only ever had one update fail. For me, it was after I got the reclaimable packages down to zero.
And on Windows 10, I couldn't upgrade from 1909 to 2004.

In both cases, the good old In-Place Upgrade came to the rescue. :-)
I was experimenting with those reclaimable packages a bit longer then you just to see if the trend of errors I had was when I removed them. All but one error occurred after removing the packages. Also now I see so many having similar WU errors including this build that I can't imagine they all removed reclaimable packages before doing updates. In any event I'm leaving the reclaimable packages alone for the time being and just observing their behavior and numbers. I went from 3 packages after build 26200.6725 down to 2 packages after this build 26200.6899 and will be leaving them and observing how the next update goes as well.

Course, at this point we're all speculating about voice AI. MS hasn't said what the actual surprise is but I guess we'll learn that tomorrow.

Here is how I solved the 0x800f0922 problem:

TL;DR (but read the full explanation below, to make sure you have the same problem that I encountered):
(1) go to HKLM/software/microsoft/windows/currentversion/winevt/channels, and delete "Microsoft-Windows-Store/Operational". Might be a good idea to save/export the key first, so you have a backup.
(2) go to HKLM/software/microsoft/windows/currentversion/winevt/channels/publishers and delete "{53e3d721-2aa0-4743-b2db-299d872b8e3d}".
(3) Reboot and retry the update.

Explanation: in C:\Windows\Logs\CBS\CBS.log, I saw an error message about a log being "declared by an existing provider" (search for that string in CBS.log), and that log was "Microsoft-Windows-Store/Operational". The GUID from #2 is from the corresponding error message.

After deleting both keys, the 0x800f0922 error was gone, and the log was re-created correctly (so I don't expect any subsequent problems from deleting those registry keys, because the log is now working correctly).

If you see similar errors, but for a different log, just modify steps #1 and #2 for the respective log names and GUID.

Hope this can help somebody :-)

- Uwe
Thanks for your help Uwe. The registry update fixed the problem for me.

Microsoft's big announcement should include that they figured out how to use the NPUs in the graphics cards, so many more computers could qualify for the Co-pilot+ AI features.

Every AI app can do it atleast on Nvidia, except the Mighty Microsoft Windows can't. At this point I think its on purpose to force every CPU manufacturer to make a NPU and waste precious silicon space.

Anyway 0x800f0983 lives on...

For the people doing repair installs, are you repairing with Version 24H2 Build 26100.6899 or Version 25H2 Build 26200.6899?
My computer with the failed update is still on 24H2, but I wondered whether it was worth repairing it with 25H2.

My computer with the failed update is still on 24H2, but I wondered whether it was worth repairing it with 25H2.
I usually recommend media that at least has '6584, at this point. Especially with the major mess that occurred this summer!

Windows Explorer is bugged before '6584, FYI. At least since '6584, the unblock option in the file context menu was finally fixed.
That should have been fixed before it was even 2025!

When I first went to 11, back in April, 2022, with 21H2, it was not a mess like it was with 24H2!

'6584 is the September CU. That's KB5065426.

I haven't heard of the Windows recovery having USB input device issues.

@Stigg did you see my post on page 6, no. 110 . I tried all on the video, + the MS Catalog, none worked.
So I went to the repair ver. with 25H2 26200.6728 (I've had 25H2 since the start of October)
How it installed - I don't know took appx: 3 - 4 hours
but it kicked me up to 25H2 (OS Build 26200.6899)
good luck, The Video is back on-line
But it's in my Update History Uninstall updates .... cheers

I had been hoping things would be smoother on 25H2! Seems not.
Well, since 25H2 was just flipping some switches in the 24H2 code, it wasn't that likely that it would smooth things out! :LOL:
