UPDATE 1/27:


 Windows Insider Blog:

[UPDATE 11/26] We are releasing Builds 26100.7309 and 26200.7309 (KB5070311) today which is a small update that includes some minor changes.

Hello Windows Insiders, today we’re releasing Windows 11 Builds 26100.7296 and 26200.7296 (KB5070311) to Insiders in the Release Preview Channel on Windows 11, version 24H2 (Build 26100) and version 25H2 (Build 26200).

Below is a summary of the new features and improvements included as part of this update separated into two sections: gradual rollout and normal rollout. The bold text within the brackets indicates the item or area of the change we are documenting.

Gradual rollout

The following features and improvements might not be available to all users because they will roll out gradually. Text bolded in brackets indicate the area of the change being documented. Please note that features and improvements that gradually roll out may not begin rolling out right away nor will they immediately show up right away.

Copilot+ PC only experiences

  • [Camera] New! As part of the Copilot+ PCs experience, you can use Windows Studio Effects, which provides AI-powered camera enhancements on an additional, alternative camera such as a USB webcam or your laptop’s built-in rear camera. To get started, go to Settings > Bluetooth & devices > Cameras and select your preferred camera from the connected cameras list. Then, open the Advanced camera options and turn on Use Windows Studio Effects. After you turn it on, you can adjust Studio Effects from the camera settings page or the quick settings menu in the taskbar. For more info on the different AI experiences, see ms/copilotpluspcs.

  • [Click to Do] These improvements are rolling out to Click to Do on Copilot+ PCs.
    • New! The Click to Do context menu now has a streamlined design that makes it easier to access frequently used actions like Copy, Save, Share, and Open. You can quickly find what you need.
    • New! Whenever a large image or table appears on your screen, the context menu automatically opens, making it quicker and easier to access the actions and results you need.

  • [Agent in Settings] These improvements are rolling out to Agents Settings on Copilot+ PCs.
    • New! The search results menu now displays more available results, making it easier to quickly find and modify your settings. A scroll bar lets you view all search results.

    • New! Recommended settings now make changes faster by showing an inline agent option for recently modified settings.

    • New! A dialog now appears when settings can’t be adjusted further. It explains why and provides an option to modify the settings as needed.
  • [File Explorer] New! As part of the Copilot+ PC experience, the File Explorer Search Box placeholder text has been updated to highlight the enhanced Windows Search.

Windows 11 PC experiences – all supported devices

  • [Desktop Spotlight] New! When Windows Spotlight is set as your desktop background (Settings > Personalization > Background), the context menu now includes two options: Learn more about this background and Next desktop background.

  • [Drag Tray] For users with the Drag Tray:1
    • New! Drag Tray now supports multi-file sharing, shows more relevant apps, and makes it easy to move files to a chosen folder.
    • New! You can now turn Drag Tray on or off from Settings > System > Nearby sharing.

  • [Keyboard] New! Keyboard backlight performance has improved on supported HID-compliant keyboards. Compatible keyboards display keys clearly in low-light environments, and the backlight adjusts to help conserve power.
  • [File Explorer]
    • New! File Explorer now offers a more consistent dark mode Key actions such as copy, move, and delete dialogs have been updated in both default and expanded views. Progress bars and chart views now align with the dark theme to improve readability. Confirmation dialogs for actions like skip, override, and file selection, along with multiple error dialogs, have also been refreshed for a cohesive look.
    • New! We’re working on consolidating the share options in the context menu into a single entry point. This change will initially be available to a small group of devices as we evaluate the best approach.
    • Fixed: File Explorer may unexpectedly not show thumbnails for video files containing certain EXIF metadata.
    • Fixed: An old white toolbar may sometimes randomly appear in File Explorer.
    • Fixed: When you right click on a file, the icon next to the entry to Open may be generic rather than matching the default app for that file type.
  • [Settings]
    • New! Keyboard settings for character repeat delay and rate, and cursor blink rate, have moved from the Control Panel to Settings. You can now find character repeat delay and rate under Settings > Accessibility > Keyboard, and cursor blink rate under Settings > Accessibility > Text cursor.

    • New! You can view the Device Card on the Settings home page. It shows key specifications and usage details of your PC. From the card, go directly to Settings > About page for more detailed information about your PC. This card will show when signed in with your Microsoft account and in the U.S. only.

    • New! About in Settings now has an updated layout that organizes device details and related options in one place. You can quickly access features such as Storage settings for faster navigation.
    • Fixed: Settings may become unresponsive when attempting to navigate to the Network & Internet section.
  • [Windows Hello] New! Windows Hello Enhanced Sign-in Security (ESS) now supports peripheral fingerprint sensors. To enroll a supported ESS fingerprint reader, go to Settings > Accounts > Sign-in options and follow the prompts. [UPDATE 11/19] This feature will roll out in a future update.

  • [Windows Share] New! 2 You can share OneDrive files through other apps. The options appear under Share using when you select the Copy link. You must be signed into your Microsoft account.

  • [Mobile Device Settings] New! You can now add and manage your mobile devices in Settings Bluetooth & Devices > Mobile On this page you can manage features such as using your device as a connected camera or accessing your device’s files in File Explorer.

  • [Game Pass] References to Game Pass in Settings are now modified to reflect updated branding and benefits.
  • [Taskbar & System Tray]
    • New! We’re updating the animations that appear when hovering over app groups on the taskbar, so that as you slide between apps you can now see the preview transition.
    • Fixed: The “Automatically hide the taskbar” setting may unexpectedly turn off, after seeing a message saying “a toolbar is already hidden on this side of your screen”.
    • Fixed: Voice access doesn’t work correctly when attempting to interact with the taskbar (calling out a number may not invoke that item).
  • [Recovery] On PCs with the settings “quick machine recovery” and “automatically check for solutions” both enabled, Quick Machine Recovery now runs a one‑time scan by default instead of repeating scans in a loop. If a fix isn’t available right away, QMR will quickly point you to the most appropriate recovery options to get you back up and running.

  • [Widgets]
    • New! You can choose a default dashboard in Widget Board settings. When live weather is showing, the Widget Board opens the first dashboard in your navigation bar instead of the most recently used one, making the experience consistent. To set your default dashboard, open the full-page Widgets Settings by selecting Settings (gear icon) in the navigation bar, then move your preferred dashboard to the top.

    • New! Dashboard icons in the Widget navigation bar now show numbers that correspond to the number of alerts from that dashboard. Navigation bar badges clear automatically when you leave a dashboard, making it easy to track what’s new.

  • [OneDrive] The new OneDrive icon is now in Accounts and Homepages in Settings.

    OneDrive.webp
  • [Input] Pens that support haptic feedback will now deliver tactile responses during certain interactions with the system UI. For example, you may feel vibrations when hovering over the close button or when snapping and resizing windows.
  • [Lock and Login Screens]
    • Fixed: It may be very slow the first time when logging into a new account.
    • Fixed: When your lock screen is set to slide show, there may be a memory leak. Memory leaks can lead to performance or reliability issues over time.
  • [Display and Graphics]:
    • Improved: We’ve improved the performance when apps query monitors for their full list of supported modes. When this happens it could previously lead to a momentary stutter on very high-resolution monitors. This work should help prevent and reduce stuttering in these scenarios.
    • Fixed: All-in-one PCs may experience issues with their brightness slider, where it unexpectedly reverts to the original brightness when interacting with it.
    • Fixed: Recently certain games may show a message saying “Unsupported graphics card detected”, although a supported graphics card is used.
  • [Smart cards]: Fixed: You may unexpectedly see STATUS_NOT_SUPPORTED (0xc00000bb) during logon when using ECC Smart Card Logon Credential.
  • [Advanced Settings] You can now enable Virtual Workspaces in Advanced Settings. Virtual Workspaces allow you to enable or disable virtual environments such as Hyper-V, Windows Sandbox, and more. To access Virtual Workspaces go to Settings > Systems > Advanced.

1 This feature is gradually rolling out, and availability will vary by device and market. Drag tray might not be available to all devices yet. For more information on Drag Tray, see KB5058499.

2 Feature availability depends on your device and market. This feature isn’t available in the European Economic Area.

Normal Rollout

This non-security update includes quality improvements. The following summary outlines key issues addressed by the KB update after you install it. Also, included are available new features. The bold text within the brackets indicates the item or area of the change.
  • [Security] Fixed: This update addresses an issue that affects Local Security Authority Subsystem Service (LSASS). LSASS could become unstable due to an access violation.
The following fixes were added on 11/26:
  • [Settings] Fixed: Settings may unexpectedly close when navigating to Settings > Privacy & Security > Microphone, Camera, or Location pages after the latest updates.
  • [Search indexer] Fixed: After the latest updates, File Explorer may no longer perform search on certain SMB shares
  • [Notifications] Fixed: After the latest updates, explorer.exe may hang (leading to the taskbar becoming unresponsive) after certain notifications.
Thanks,
Windows Insider Program Team

*Functionality will vary by device and market; text actions will be available across markets in select character sets. See aka.ms/copilotpluspcs.

One weird thing after this update was done on 3 different machines.

DISM /ONLINE /CLEANUP-IMAGE /CHECKHEALTH found
The component store is repairable.
The operation completed successfully.

While
DISM /ONLINE /CLEANUP-IMAGE /SCANHEALTH was clean.
[==========================100.0%==========================] No component store corruption detected.
The operation completed successfully.

Then running again after the /SCANHEALTH no more repairable. ️

DISM /ONLINE /CLEANUP-IMAGE /CHECKHEALTH
No component store corruption detected.
The operation completed successfully.

Looks like /CHECKHEALTH the 1st time found something left over from previous runs of /SCANHEALTH. 😵‍💫🤷‍♂️

Exactly the same on 3 different machines, pretty confusing. 😵‍💫

You can write your own script or modify the UUP script to correctly generate the ISO. Microsoft's learn official website also provides instructions on how to generate ISOs.

I built my own ISO and I've done clean installs on 3 systems and simply updated another 3 so far, all working perfectly.

Hello from Brasil. I'm a newbie, and I have bought this new Dell Alienware (25H2, 26200.7171). It's working fine with a single problem, so I'm trying to put it in the Insider Program. I'd like to begin with the Release Preview, so I choose this option at the Windows Update/Program Windows Insider. I didn't wait too much for the option 26200.7309 to start showing at my Windows Update page. I thought, nice, this will be fast! So the downloading process happened, and then the installation process began. It's a little slow and... stopped with an error and the Retry button available. I have tried it 3 times with no success. Now I'm kind of stuck. The update keeps appearing, and I keep trying it with no success. Did I make some mistake? Is there anything somebody could advise me to do? Now I'm with no clues and just waiting for this thing to solve itself.

Now that I paid more attention, I saw the error message number. It was an installation error 0x800f0991. Does anybody know what that means? Thank you.

The error 0x800f0991 typically occurs during Windows updates due to corrupted system files, missing dependencies, or issues with update components.

I am sorry but I think Chris Titus is correct about Windows 11. I spent about 50 minutes downloading an ISO from The Dump in order to perform an In Place upgrade Repair. The same way I have been doing it for years. I and running the Widgets with the Co Pilot preview and it keeps giving me Weather and my location as Washington DC. I tried all possible methods to fix this. I normally do not use Widgets but since this is an Insider Build, I will until it goes to release. The update did well, so I shut off my PC to do some other things. When I turned it back on I checked Windows update and it starting downloading 25H2 and then it restarted and I checked WU again and it downloaded the Runtime. There has got to be an issue with 26200.7309 and it failed when I first tried to update it. This was the first time any update failed for me. So I may just remove the Widgets and Copilot.

Problem solved. I removed the Web Experience Pack.
