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.

Improvements​

This security update contains fixes and quality improvements from KB5079473 (released March 10, 2026), KB5085516 (released March 21, 2026), KB5079391 (released March 26, 2026 - no longer offered), and KB5086672 (released March 31, 2026). 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.
  • [Secure Boot]
    • New! The status of Secure Boot certificate updates on your device may be displayed in the Windows Security app (Settings > Privacy & security > Windows Security). Learn more about the status alerts via badges and notifications. These enhancements are disabled by default on commercial devices.
    • 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 addresses an issue where the device might enter BitLocker Recovery after the Secure Boot updates.
  • [Networking] This update improves reliability when Windows uses SMB compression over QUIC. After you install this update, SMB compression requests over QUIC complete more consistently, reducing the likelihood of timeouts and supporting smoother, more dependable performance.
  • [Remote Desktop] This update improves protection against phishing attacks that use Remote Desktop (.rdp) files. When you open an .rdp file, Remote Desktop shows all requested connection settings before it connects, with each setting turned off by default. A one-time security warning also appears the first time you open an .rdp file on a device. For more information, see Understanding security warnings when opening Remote Desktop (RDP) files.
  • [Reset this PC (known issue)] Fixed: This update addresses an issue that might cause device reset to fail when using the “Keep my files” or “Remove everything” options. This might occur after installing the March 2026 (KB5079420) Hotpatch security update.
  • [Vulnerable driver blocklist] This update introduces a security hardening change that adds known vulnerable kernel drivers to the Microsoft vulnerable driver blocklist. Backup applications that rely on blocked drivers might experience failures when attempting to mount or manage disk images.

    These apps relying on blocked drivers might display error messages, including "The backup has failed because Microsoft VSS has timed out during the snapshot creation" or VSS_E_BAD_STATE. Affected users should update to a newer version of their application that uses newer drivers that include the required protections. For more information, see April 2026 Windows security updates introduce protections to known vulnerable kernel drivers.
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 and the April 2026 Security Updates.

Windows 11 servicing stack update (KB5088467)- 26100.8247​

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​

Symptom

Some devices with an unrecommended BitLocker Group Policy configuration might be required to enter their BitLocker recovery key on the first restart after installing this update.

This issue only affects a limited number of systems in which ALL of the following conditions are true. These conditions are unlikely to be found on personal devices not managed by IT departments.
  1. BitLocker is enabled on the OS drive.
  2. The Group Policy "Configure TPM platform validation profile for native UEFI firmware configurations" is configured, and PCR7 is included in the validation profile (or the equivalent registry key is set manually).
  3. System Information (msinfo32.exe) reports Secure Boot State PCR7 Binding as "Not Possible".
  4. The Windows UEFI CA 2023 certificate is present in the device’s Secure Boot Signature Database (DB), making the device eligible for the 2023‑signed Windows Boot Manager to be made the default.
  5. The device is not already running the 2023-signed Windows Boot Manager.
In this scenario, the BitLocker recovery key only needs to be entered once -- subsequent restarts will not trigger a BitLocker recovery screen, as long as the group policy configuration remains unchanged. For help finding your BitLocker recovery key, see the article, Find your BitLocker recovery key.

Enterprises are recommended to audit their BitLocker group policies for explicit PCR7 inclusion and check msinfo32.exe for their PCR7 binding status before installing this update. (See Option 1 below.)

Workaround

This issue is addressed in KB5089549. After installing KB5089549, devices with this incompatible group policy configuration are prevented from installing the 2023-signed Windows Boot Manager. If your device was impacted, Event ID 1032 will appear in the System event log when installing Windows updates: "The Secure Boot update Boot Manager (2023) was not applied due to a known incompatibility with the current BitLocker configuration."

If you receive Event ID 1032, Microsoft strongly recommends removing the Group Policy configuration before installing updates so that you can install the 2023-signed Windows Boot Manager and continue to receive the latest Secure Boot protections.

Remove the Group Policy configuration before installing the update (Recommended)
  1. Open Group Policy Editor (gpedit.msc) or your Group Policy Management Console.
  2. Navigate to: Computer Configuration > Administrative Templates > Windows Components > BitLocker Drive Encryption > Operating System Drives.
  3. Set "Configure TPM platform validation profile for native UEFI firmware configurations" to "Not Configured".
  4. Run the following command on affected devices to propagate the policy change: gpupdate /force
  5. Run the following command to suspend BitLocker (where BitLocker is enabled on the C: drive): manage-bde -protectors -disable C:
  6. Run the following command to resume BitLocker (where BitLocker is enabled on the C: drive): manage-bde -protectors -enable C:
  7. This updates the BitLocker bindings to use the Windows-selected default PCR profile.
If you do not wish to remove this Group Policy configuration, you can install the new Windows Boot Manager by temporarily suspending BitLocker and installing the Secure Boot update. To do this:
  1. Run the following command to suspend BitLocker (if BitLocker is enabled on the C: drive): manage-bde -protectors -disable C:
  2. Run the following command: Start-ScheduledTask -TaskName "\Microsoft\Windows\PI\Secure-Boot-Update"
  3. Restart the device.
  4. Once the new Windows Boot Manager is successfully installed, enable BitLocker by running the command: manage-bde -protectors -enable C:

Symptoms

After installing this update, the security warning that appears when opening Remote Desktop (RDP) files might not display correctly in some cases.

This issue can occur when you use more than one monitor with different display scaling settings (for example, one display set to 100% and another set to 125%). When this happens, the warning window might show overlapping text or partially hidden buttons, which can make the message difficult to read or interact with.

Workaround

This issue is addressed in KB5083631.

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

Caution: 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.

Updated yesterday. No issues found. One strange addition in this build; Settings - Privacy and Security - Windows Security - Device security (Defender) When secure boot is turned on; One extra feature is visible; Secure Boot. Can have 3 statuses. A Green icon, a yellow icon, a red icon. Green is OK but what if it says Yellow or Red? MS does not mentioned what to do next about it..... Waking those dogs up yet again... 😆

cjee21 released an updated version on GitHub of his program; Check-UEFISecureBootVariables. See attachment. Now it shows some SHA256 checksum of the certificates. (GitHub - cjee21/Check-UEFISecureBootVariables: PowerShell scripts to check the UEFI KEK, DB and DBX Secure Boot variables as well as scripts for other Secure Boot related items.) Can't see the relation of the SHA256 to which certificate. Looked at the PCA2011 intermediate certificate. It does have a Thumbprint (SHA256) but does not match any of the Checksums that this program is showing. Important is the the checksum matches with what was expected.

  • Green (Checkmark): Secure Boot is on and all required certificates are applied.
  • Yellow (Warning): Secure Boot is on, but an older certificate is in use, requiring a Windows update.
  • Red (Stop/X): Serious issue; Secure Boot is either off or using expired certificates that cannot be updated automatically, potentially requiring a BIOS/firmware update.

Yes I know. I can read. But basically it is saying will be fixed. Not how to solve it. Wait on a update or on a BIOS update. (what if the motherboard is to old and no BIOS updates are available for this change of situation?) Seen many issues to date and they were all fixable without any help of MS. It should only look at the current state not at the default state. MS is not telling us under what conditions a yellow or red mark appears. By doing it this way it raises more questions than answers. People want to solve the situation if there is one. MS is taking it's time with that CA 2023 or CA2024 by now. We are arriving in May and then it must have everything in place in one go otherwise in June "things" will hit the fan..... Seen at their troubles with 8116 & 8117... It's not looking good.....

Okay, I don't know wtf just happened but my 2/@ W and upper center volume keys stopped working all of a sudden. I ran the troubleshooter and it's partially working again

@Senecio @Awesomehorse I had something like that happen in my HP Desktop computer a few days before this update. The 3 keys (f1, f2,f3) that handle volume in my W11 all of the sudden stopped working. I solved the issue by rebooting. Perhaps a reboot would have solved your issue as well.

FWIW, this update seems to have gone very well in my desktop. It fixed an issue that I think affected some computers but not all. A few programs that I use everyday stopped working after March's Windows update. Now, after installing April's updates, they all (and I mean, a few programs) work as they always have. I am happy :-)

KB5083769 (26200.8246) Quality update and 2026-04 .NET Framework Security Update KB5082417 installed very fast on both my 2 systems. DISM and SFC completed successfully on my Acer laptop but SFC found corruption on my Asus laptop that were successfully repaired, when running SFC again no issues were found. KEK (secure Boot key) was not updated on my new Acer SF14-51T laptop but was successfully installed om my 2023 ASUS OLED Vivobook?
Update April 24:
Just received the KEK (Secure Boot key) for my Acer SF14-51T laptop so both my systems have now the new 2016 Secure Boot keys)

Thanks @bo elam - I had stupidly assumed that the three reboots which happened during the update would have taken care of that, but I just did another and lo and behold, the issue is now resolved. :rolleyes:

I decided to run the last DISM command from my post in this thread, I ran it after the person I was helping to run this command gave up on the laptop that had an error. I just ran it because I had the install.wim file now:

Code: 
DISM /Online /Cleanup-Image /RestoreHealth /Source:install.wim

Deployment Image Servicing and Management tool
Version: 10.0.26100.5074

Image Version: 10.0.26200.8246

[==========================100.0%==========================]
The restore operation completed successfully.

KEK CA 2023 updates need to be installed on older PC's.
Your Acer SF14-51T was released in 2024. All PC's from this time are already supported in the factory BIOS.

This is not necessary. When you are on 26200.8246 and secure boot inside your BIOS is turned on; the option will appear under Device security inside Defender. If it's reflecting the BIOS status or does some more checks is unknown.

One note on that ViVetool; those numbers are feature dependent and are active for a certain period. Once the feature has been implemented those numbers will be removed inside the feature-set. (inside the registry) These feature-sets lay dormant. Can be switched on or off. You can list them using vivetool.exe /Query By this method MS can write code for a certain feature and adapting it during time and during multiple updates. Once MS is confident the implementation is complete they can turn this feature on. If there are no issues with it and it's successful implemented they remove that feature from that list to make it permanent. So with every update new numbers can appear and old ones can disappear. If a feature is there or not is depending on the build.
