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.

  • Added Secure Boot release note: This update adds a new SecureBoot folder under C:\Windows on eligible devices.
  • Added Daylight saving time (DST) update.

Improvements​

This update includes new features and quality improvements that were part of the following update:
This update addresses security vulnerabilities documented in the following guide:
The following summary outlines key quality improvements addressed by this update. The bold text within the brackets indicates the item or area of the change.
  • [Secure Boot]
    • With this update, Windows quality updates include additional high confidence device targeting data, increasing coverage of devices eligible to automatically receive new Secure Boot certificates. Devices receive the new certificates only after demonstrating sufficient successful update signals, maintaining a controlled and phased rollout.
    • This update adds a new SecureBoot folder under C:\Windows on eligible devices. The folder contains example scripts intended for organizations with IT professionals who actively manage updates across their device fleet. These scripts can be used to detect Secure Boot certificate update status and automate deployment via a safe rollout mechanism in an Active Directory environment. For more information, see Sample Secure Boot E2E Automation Guide.
  • [Boot manager servicing update]
    • This update improves startup reliability after boot file updates, so devices start normally without entering BitLocker recovery.
    • (Known issue) Fixed: This update addresses an issue where some devices might enter BitLocker Recovery after updating boot files on systems with certain Trusted Platform Module (TPM) validation settings, including invalid PCR7 (Platform Configuration Register 7) configurations. This might occur after installing the April 2026 security update (KB5083769).
  • [Connectivity] This update improves the reliability of Simple Service Discovery Protocol (SSDP) notifications to help prevent the service from becoming unresponsive.
  • [Daylight saving time (DST)] This update supports the 2023 DST change for the Arab Republic of Egypt.
If you've already installed previous updates, your device will download and install only the new updates included in this package.

Windows 11 servicing stack update (KB5092762)- 26100.8456​

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​

Symptoms

After you install this update (KB5089549), some devices might fail to complete installation with error code 0x800f0922. This issue occurs on devices that have limited free space on the EFI System Partition (ESP), especially if it has 10 MB or less available.

What you might experience on affected devices:
  • The update installs successfully during the initial phases.
  • The installation fails during the restart phase at approximately 35–36% completion.
  • Windows then rolls back the update.
  • You may see the message:
    “Something didn’t go as planned. Undoing changes.”
  • The installation fails with error code 0x800f0922.
As a result of this issue, you might see log entries similar to the following in C:\Windows\Logs\CBS\CBS.log, indicating insufficient free space on the EFI System Partition:
  • SpaceCheck: Insufficient free space
  • ServicingBootFiles failed. Error = 0x70
  • SpaceCheck: <value> used by third-party/OEM files outside of Microsoft boot directories
Workaround

This issue is addressed in KB5089573.

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.

Install this update

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

Available​
Next Step​
Included
This update downloads and installs automatically from Windows Update and Microsoft Update.
Included
To install this release from the Microsoft Update Catalog, select the option that matches your device architecture (arm64 or x64), and then follow the instructions.

If you want to remove this update

Before you decide to remove this update, see Understanding the risks: Why you should not uninstall security updates.

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.

@xomuz I had that problem too(I checked after reading your post).
I did a good search in internet, and found that you need to restart explorer and it will reappear.
Note it is still there after a shutdown and later boot, also.

The script gathers all of the known Secure Boot servicing reg keys (nothing new), telemetry data (PC model and BIOS version), and a summary of Event ID's. It's primarily intended for IT admins to create their own tools on top of the collected data.

What's funny, is the Microsoft Option ROM is officially considered optional (MS doesn't require OEM's to push it out), but Windows wants it to pass certification. This fact is confirmed by the Windows Security Center. If you don't have the Option ROM, it's not called out specifically but you don't get the fully compliant message.

Installed but spent ages trying to fix Dism. RestoreHealth would fail with "unable to find files". Tried local source, restricting to Windows Update nothing worked so in the end did an In Place Upgrade which was a battle in itself. Finding an ISO which didn't want to wipe my apps (option greyed out) was difficult. Made the latest ISO from UUP Dump but no option to keep apps just personal files. Eventually downloaded ISO from Windows Download Page which still has the option to keep files and apps and after upgrade no more Dism errors. So did a backup.

You definitely have to get the exact ISO match if you just want to do a repair install and let it keep all your apps and settings. If you don't see that option for keep apps and settings you have the wrong one. 😉

The WinRE location thing appears broken, I should probably add an option to scan an extracted boot.wim from a folder.

For me this update turned into a update from H*LL. Last night I finally got around to restarting my computer. It took over two and a half hours only be greeted with a rollback that took hours. I'm not sure of the time because I had to get some sleep. Tonight I gave it another try. The process didn't take long but it failed again. I tried it a third time and this time it installed without any problems. So far I haven't noticed any problems.

I seem to be stuck in slow wifi mode. Someone mentioned checking to see if an Intel networking service was installed, but I can't remember the details nor where I found it.
