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.

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.

I doubt it is not widespread. I have three Windows 11 25H2 computers. My primary has Windows 11 pro and this update installed without any problem. The other two has Windows Home and both of them could not install the update, at the end of installing the update it stated "retry" on both computers. Retry was not effective.

If you look at previous updates I have never seen as many people using this forum stating they had problems installing the update. Previously people on this forum have stated how fast and without any problems they were able to install the updates (excluding insider builds).

I performed a repair from Windows Update as indicated in this thread. I'm at build 26100.6899. It's practically the same as an In-Place Upgrade. The two reclaimable packages are back, so I'm leaving them.

Yesterday I made a backup. If Microsoft fixes the problem with this KB, I'll restore the backup to apply the new KB.

This update is not going well at all for me!

I saw the little "update required" icon on my taskbar this morning and, knowing that there was a major update due, I proceeded to initiate the update without taking any prior precautions. I'm working on a new laptop that already had 24H2 and that was up-to-date and I'd seen videos last night that said it only took 5 minutes so I thought I'd just get the update out of the way and get on with my day.

What actually happened is that it slogged away for a solid hour, then announced that something had gone wrong but not to worry because it was undoing everything. The undoing has now been slogging away for a good while. This is really messing up my plans for the day.

Can anyone tell me what is wrong and what I'll have to do about it when the update is finally backed out? I have no idea what's gone wrong. It's especially frustrating because so many of you have had problem free updates from the looks of it.

I had the same symptoms on PC, with Win 11 Pro 25h2 build 10.0.26200.6725. This update failed twice, and 3rd time when manually downloaded this update from Windows Catalog.

So it's borked update, which Win 11 is known for. Just pause your updates till they sort it out, unless you're willing to reinstall OS with "keep settings and apps" option.

I wasn't really affected by previous broken Win 11 updates, but this one hit me. I guess there always is a first time for something.

On Oct 15, 2025, all machines insider and non-insider Builds have a problem with the PCs not showing on the network and Intel DSA failing to run a scan.
The problem is caused by some of those hidden features enabled by Microsoft via CFR, and it is now common to all builds.
The only way I found to eliminate the problem is by issuing "vivetool /fullreset".
There are way too many enabled features to try isolating the culprit.
Did anybody figure out which features IDs are causing the bug?
The problem happens with all Builds, Public, R.P., Beta, Dev, Canary.
Pretty frustrating. 🤬🤷‍♂️



1760550393177.webp

Edit:
Later today Microsoft changed some of those hidden features and fixed the problem on one machine with 26200.6899 and one Canary machine with 27965.1.
I still have several other machines that are still failing with different Builds. I really hope they fix them all.
This is ridiculous. 😵‍💫🤬🤷‍♂️

Here are the 4 that they fixed up to now. Who knows what they are changing with their experiments?

It is a screwup from Microsoft, cannot see any PCs on my private home network either. That is the other symptom of this bug.

If you look at previous updates I have never seen as many people using this forum stating they had problems installing the update. Previously people on this forum have stated how fast and without any problems they were able to install the updates (excluding insider builds).

People are complaining not only here, this update (if it, unfortunately, was successfully installed) causes a critical problem in IIS service. In particular, one post on Microsoft forum says that it halts processing of credit cards for "tens of thousands of merchants". From other posts, admins had to uninstall this update on all affected PCs.

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 :-)

This worked....... BUT not right away let me explain as it might help others.
For me the above fix would not work in 24H2 but did work in 25H2.

Last week I used the enablement package to update to 25H2
Then yesterday my update failed during the restart with 0x800f0922 and needed to roll back.
I tried everything but nothing worked so I removed last weeks feature update and went back to 24H2, again it still failed with 0x800f0922 but this time earlier, during installation not during reboot.

I then tried the above fix and deleted both files, rebooted, but it still failed.
Then I reinstalled the enablement package to take it back to 25H2.

I checked the two files were still deleted from the registry and...... success, this time the update worked in 25H2
so for me, at least, the above fix worked in 25H2 but not in 24H2

And of course, your privacy will be totally protected! Just look at the statement that assures you of that fact! :rolleyes:

"The computer will be able to see what we see, hear what we hear, and we can talk to it and ask it to do much more sophisticated things."

Well for crying out-loud... Microsoft currently has me shaking in my boots as it is right now. I would wish for it to be some kind announcement that new Secure Boot Certificates are going to be distributed to every PC via Windows Update after the first of the year... so the end user can stop worrying about all that. Now that, would be "something big" to me. 🤣

    The Samsung NVMe PM9C1a 1024GB SSD does not use a Phison NAND controller. Instead, it uses Samsung's in-house developed Piccolo (S4LY022) 6-Core 4 Channel Controller. The PM9C1a utilizes a controller built using Samsung's 5-nanometer process and seventh-generation V-NAND technology. 🤔
