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

Follow @WindowsUpdate to find out when new content is published to the Windows release health dashboard.

Highlights

Gradual rollout​

A gradual rollout distributes a release update over a period of time instead of all at once. This means that users receive the update at different times, and it might not be immediately available to all users.
  • [Recall] New! Recall opens to a personalized homepage that puts your recent activity and top-used apps and websites front and center, making it easy to pick up where you left off. After turning on snapshot collection, the homepage highlights key productivity features like Recent Snapshots, which show the latest snapshots to help you quickly resume tasks, and Top Apps and Websites, which display the three apps and websites you’ve used most in the past 24 hours. You can set filters in Settings to control which apps and websites are saved in snapshots. A new navigation bar on the leftmost side of the screen provides quick access to Home, Timeline, Feedback, and Settings.

  • [Click to Do] New! When you launch Click to Do for the first time, you'll see a quick interactive tutorial. It shows how to complete tasks faster by demonstrating actions on both text and images—such as summarizing large blocks of text or removing image backgrounds. To revisit the tutorial later, select More options > Start tutorial.

  • [General] New! When an app requests access to location, camera, microphone, or other device capabilities, Windows shows a redesigned system dialog box. To emphasize the privacy prompt, the screen dims slightly, and the prompt appears at the center of the screen.
  • [Taskbar]
    • New! The larger clock with seconds is now back in the notification center, displayed above the date and calendar. To turn this option on, go to Settings > Time & language > Date & time, and turn on Show time in the Notification Center.

    • Fixed: If you accidentally click and drag your mouse across the taskbar preview thumbnail, the preview might stop working.
  • [Search on the Taskbar]
    • New! When you use Search from the Windows taskbar, a new grid view will help you more quickly and accurately identify the desired image within your search.
    • New! Search on the taskbar now provides clearer status information. If your search results are incomplete while your PC is organizing files in the background, Windows shows a notice with a link to check progress. You can dismiss the notice when you're done. There is also a status for files and folders, so you can easily tell whether they’re available online (cloud) or stored on your device.

  • [Lock screen] New! More widget options and support for lock screen widget personalization (previously referred to as “Weather and more”) are rolling out. After initial launch with Windows Insiders in the European Economic Area (EEA), these updates are expanding to all regions. You can add, remove, and rearrange lock screen widgets such as Weather, Watchlist, Sports, Traffic, and more. Any widget that supports the small sizing option can be added. To customize your lock screen widgets, go to Settings > Personalization > Lock screen.

  • [File Explorer]
    • New! Dividers now separate top-level icons in the File Explorer context menu.
    • New! When you're signed in with a work or school account (Entra ID), File Explorer will display people icons in the Activity column and the Recommended section at the top of File Explorer Home. Hover over or select a person's icon to open their Microsoft 365 Live Persona Card, which shows who they are and how they're connected to the file.

    • Fixed: If you try to use the unblock open in Properties for a file, it still shows as blocked when you open Properties the next time.
  • [Windows Hello]
    • New! As part of the enhanced passkey features released in September 2023, you’ll see a redesigned Windows Hello interface. These modernized visual updates support fast, clear communication that appear across multiple authentication flows, including the Windows sign-in screen, passkey, Recall, the Microsoft Store, and more.

      The Windows security credential experience for passkey offers a cleaner, more intuitive interface designed to support fast, secure sign-in. You can now easily switch between authentication options such as passkeys or connected devices.
    • Fixed: Windows Hello might recognize your face on the login screen, however it would still fail and then prompt you to enter your pin. If you continue experiencing issues, you might need to go to the Facial Recognition section under Settings > Accounts >Sign-in options and select Improve recognition.
    • Improved: Fingerprint login after standby is now more robust.
  • [Settings]
    • New!  Windows activation and expiration prompts match the Windows 11 design and appear as system notifications when action is required. There also have been improvements to messaging under Settings > System > Activation.
    • New! You can go to Settings > Privacy & security > Text and Image Generation to see which third-party apps have recently used generative AI models provided by Windows. You can also choose which apps are permitted to use them—putting you in charge of your device’s AI experience.

    • New! As part of the Copilot+ PC experience, the agent in Settings helps you quickly find and change settings. Initially available on Snapdragon®-powered Copilot+ PCs, agent in Settings now supports AMD- and Intel™-powered Copilot+ PCs. It currently works only when your primary display language is set to English.

    • Fixed: Settings might crash if you attempt to add a security key under Settings > Account > Sign-in options.
  • [Task Manager] New! Task Manager now uses standard metrics to show CPU workload consistently across all pages, aligning with industry standards and third-party tools. If you prefer the previous view, you can enable a new optional column called CPU Utility in the Details tab to display the earlier CPU usage value shown on the Processes page.

  • [Widgets]
    • New! Multiple dashboards are now available in your Widgets Board. This gives you more space for your favorite widgets and helps you stay informed with a feed that connects you to current events. A new navigation bar on the left side makes it easy to switch between your widget’s dashboard and other views like the Discover feed. After initial launch in the EEA, these updates are expanding to all regions.

    • New! A new visual experience is available for the Discover feed on the Widgets Board. The layout is more organized, personalized, and engaging. Copilot-curated stories are now included, offering a well-rounded view of each topic with summaries, videos, and images from trusted MSN premium publishers. To customize your feed, go to Widgets > Discover dashboard > Personalization settings.

  • [Windows Backup for Organizations] New! Windows Backup for Organizations is now generally available! Experience seamless device transitions with enterprise-grade backup and restore. Whether you're refreshing your organization’s devices, upgrading to Windows 11, or deploying AI-powered PCs, this solution helps sustain productivity with minimal disruption, ensuring business continuity and organizational resilience.

  • [PowerShell 2.0] Starting in August 2025, Windows 11, version 24H2, will no longer include Windows PowerShell 2.0. This legacy component was introduced in Windows 7 and officially deprecated in 2017. Most users won’t be affected, as newer versions such as PowerShell 5.1 and PowerShell 7.x remain available and supported. If you use older scripts or tools that depend on PowerShell 2.0, update them to avoid compatibility issues.

  • [Live captions] Fixed: Changing the opacity of live captions in Settings > Accessibility > Captions > Caption Style, has no effect.
  • [Input]
    • Fixed: Attempting to type Chinese with an IME after copying something with CTRL + C can result in the first character not displaying.
    • Fixed: An underlying issue related to textinputframework.dll could result in certain apps like Sticky Notes and Notepad crashing.
  • [dbgcore.dll] Fixed: An underlying issue with dbgcore.dll could result in certain apps, including explorer.exe, crashing.
  • [Kerberos] Fixed: There might be an underlying crash in Kerberos when attempting to access a cloud file share.
  • [Login] Improved: Addressed some underlying cases which could lead to you seeing a blank white screen, or a screen saying, "just a moment", for a few minutes when logging into your PC.
  • [Miracast] Fixed: An issue where, on certain devices, audio would initially play but stop a few seconds after casting to a TV.

Is 25H2 only for Insiders ?
You know, it's probably only for RP insiders. I'm in RP and this is a Cumulative Preview so I'm mixing them up again, apologies.

Updated from 26100.1150 directly to 26100.5074 and used the eKB to upgrade to 25H2 26200.5074 on an unsupported device. Very smooth process with no issues.

25H2 as an iso is available on UUP ... 26200.5074

I'm not an Insider at all (no interest), but I have formed the iso from UUP and installed it as an update off a USB after making an Incremental Macrium backup. Worked fine.

Did that to test what undesirable (to me) changes may be coming, then reverted to 24H2 via the Macrium backup.

It's also obvious that doing this via UUP when not an Insider will require forming the iso and installing it for each 25H2 update. This'll work ok but it's just tedious.

I used the MSU Brink added to the 26200.5074 thread. and i got 25h2 on a unsupported machine.
Or so it says 25h2 26200.5047. Not on the insider channels either. But did not get any off the new features like start menu

I got 2 more machines in R.P. channel that are failing to update with W.U.
I will have to try the Repair version again. What a waste of time and downloaded data from the internet. I hope I don't go over my monthly limit.
AT&T will change me extra. 😝🤬🤷‍♂️

I have just updated to 26200.5074. So that's me on 25H2 now. Great. So what's the difference I ask myself? Well let's have a look..

The start menu is the same.
File explorer is the same.
Task manager is the same.

Oh whatever, everything is the same.

In fact there has been no real difference since I first installed Windows 11 on launch day. Pathetic.

After this update my CPU for the first time has began reading 0% sometimes and I don't know if this is normal or not

it still jumps normally to things like 30%

Still downloading 26100.5074 via Insider RP, and noticed this Optional update. Perhaps I'd give it a try later on...

About KB5064081 26100.5074 ...


I have 3 laptops making a small home network. Two of them are on 24H2 and the 3rd on Lite (old machine, used mostly as legacy backstop). Until today, the two on 24H2 were up to 26100.4946. All three machines saw each other on the network with all the usual file utilities and so on.


I updated the 24H2 machines to 26100.5074. This went quite normally, unexceptional. SFC and DISM health checks after updating showed no error. As usual, I had made Macrium Incremental images of both the 26100.5074 installations before the updates.


Then came the headscratcher. The legacy machine on Win11 Lite and the two updated 24H2 machines recognised and connected on the network; that is the Lite machine talks to both those updated to 26100..5074. But the two updated 24H2 machines now on 26100.5074 refused to talk to each other until the irritating "credentials" insert was satisfied - these machines see each other but insist on "credentials" even though 1) all the network settings are on open as always; 2) neither need this to talk with the Lite machine; 3) when one of the 26100.5074 machines is restored to 26100.4946 from the Macrium image, everyone talks to everyone again without "credentials" as usual.


Suggestions ?

Your problem remind me someone in competing forum that complain that he has in many IP builds network problem. So why it will not be in stable build ?

I had the same problem in the past. My solution was to log off from both Windows accounts, and then log on again. After that, both machines recognized each other again.

After the failed ARM update, I have successfully installed the update on the much older AMD desktop. Seems OK so far. I'll have another go at the laptop tomorrow.
I successfully installed on the ARM laptop this morning, after running a modified version of my usual post install clean up script. Essentially, I ran these commands from CMD running as administrator:

DISM.exe /Online /Cleanup-image /Restorehealth

sfc /scannow

ipconfig /flushdns

Dism.exe /online /Cleanup-Image /StartComponentCleanup

chkdsk c: /R


SFC / scannow took a very long time and found and corrected errors. I don't suppose the ipconfig /flushdns is necessary. chkdsk c: /R always takes a long time, but didn't find any problems.

This morning I just clicked Retry on the updates page.

Installation was fast and completely normal.

Phew.

I'm not on the insider program, so I now have the 24 h2 build 26100.5074

Good luck to anyone else struggling.

Why /Restorehealth ?
Run /Scanhealth 1st, if that is clean there is no need for /Restorehealth. 😉
