Windows 11 Insider Experimental (26H1) Preview Build 28200.1873 (https://learn.microsoft.com/en-us/windows-insider/release-notes/experimental-26-h1/preview-build-28020-1873).

These release notes apply to those who are in the Canary 28000 series Channel.

Changes and Improvements gradually being rolled out

• This update includes a small set of general improvements and fixes that improve the overall experience for Insiders running this build on their PCs.

[Xbox Mode]

• Xbox full screen experience is now Xbox mode
• We've added an improved first run experience when entering Xbox mode

Feedback: Share your thoughts in Feedback Hub (WIN + F) under Gaming and Xbox > Gaming Full Screen Experience.
[Touch Keyboard Experience for Voice Typing]

• We're updating the experience when you use voice typing with the touch keyboard to make it feel more streamlined and intuitive. The new design removes the previous full‑screen overlay and instead shows voice typing animations directly on the dictation key, helping you stay focused on what you're doing without extra visual distractions.

FEEDBACK: Please share your feedback in Feedback Hub (WIN + F) under Input and Language > Voice Typing (Windows key plus H).
[Storage]

• Improved the performance when navigating to see storage on large volumes via Settings > System > Storage > Advanced Storage Settings > Disks & Volumes.
  
• Updated Settings > System > Storage, so rather than seeing a UAC prompt immediately when you go to the page, you'll only see it when going to view temporary files.
  

[Network]

• Fixed issue causing Settings > Network & Internet > Data Usage to show large unrealistic values in recent Insider builds.
  

[Other]

• Improved performance of launching startup apps after boot (apps which display under Settings > Apps > Startup).
  

Windows 11 Insider Experimental (26H1) Preview Build 28020.1921 (https://learn.microsoft.com/en-us/windows-insider/release-notes/experimental-26-h1/preview-build-28020-1921)

As a reminder, these release notes apply to those who are in the Canary 28000 series Channel. As we begin the transition to the updated Windows Insider Program, all new build release notes will be labeled under the new channel names, even though Insiders in the Canary 28000 series Channel may not yet find themselves having transitioned to Experimental (26H1). See the Windows Insider Blog (https://aka.ms/wipchangesrollout) for more details.

[Windows Insider channel movement]
As announced in the Windows Insider Blog (https://aka.ms/wipblog5-1-2026), we will begin moving users in the Canary 28000 Series Channel to the new Experimental (26H1) channel.

[Task Manager]
We're making a few improvements to Task Manager:

• We're updating Task Manager to provide better insight into NPU usage for PCs that include an NPU. New optional NPU and NPU Engine columns are now available on the Processes, Users, and Details pages. The Details page also adds NPU Dedicated Memory and NPU Shared Memory optional columns to give you deeper visibility into how workloads are using NPU resources. Additionally, if there are neural engines that are part of a GPU, they will now appear on the Performance page, providing a more complete view of AI‑related system activity.
• We're also adding a new optional Isolation column to the Processes and Details pages, allowing you to see which apps are running in an AppContainer.
• Fixed accuracy of CPU speed display on the Performance page of Task Manager for VMs after resume from hibernate, so it doesn't sometimes show unexpectedly high unrealistic numbers.

Once these changes are available to you, you can add any of the new columns by right‑clicking a column header in Task Manager and selecting them from the menu.

Feedback: Share your thoughts in Feedback Hub (WIN + F) under Task Manager.

Gradual Rollout

Windows 11 PC experiences

This section highlights some new features and enhancements for Windows 11 PCs, including AI-powered capabilities, continuous innovation, and performance improvements.

• [Gaming] New! Xbox mode is available on Windows 11 PCs, including laptops, desktops, and tablets. Inspired by the Xbox console experience, Xbox mode offers a streamlined, full‑screen interface that puts your games front and center while minimizing background distractions. Xbox mode is designed for those moments when you want to lean back, pick up a controller, and focus on the game. Enter Xbox mode from the Xbox app, Game Bar settings, or by pressing Windows logo key + F11. For more information, see Xbox Mode Begins Rolling Out to Players on Windows 11PCs Today.
  
• [File Explorer]
  
  • New!  This update expands the list of archive formats that can be used in File Explorer to include uu, cpio, xar, and NuGet Packages (nupkg).
  • With this update, View and Sort preferences are preserved in folders such as Downloads and Documents when apps launch File Explorer directly to those locations.
  • This update removes a white flash that could appear when opening This PC or while resizing the Details pane in dark mode.
  • This update improves the reliability of relevant explorer.exe processes so they stop after closing File Explorer windows.
• [Input]
  
  • New!  You can feel haptic feedback effects on compatible input devices when performing certain actions, such as aligning objects in PowerPoint, snapping or resizing windows. These haptic signals can be turned on or off in Settings > Bluetooth & devices > Mouse, Touchpad, or Pen > Haptic signals. This experience is supported on Surface Slim Pen 2, ASUS Pen 3.0, and MSI Pen 2 with haptic feedback. Support for additional compatible devices, including select mice such as Logitech MX Master 4, might become available as hardware partners release updates.
    
  • New!  Voice typing on the touch keyboard now looks simpler and more intuitive. The updated design removes the full‑screen overlay and shows voice typing animations directly on the dictation key, helping you stay focused without extra visual distractions.
    
  • New!  The Arabic 101 Legacy keyboard layout is now available. You can add it when selecting a keyboard for Arabic under Time & Language > Language & Region. This option is for those who prefer the keyboard design used before recent changes with AltGr.
    
  • This update improves the reliability of setting custom tools under Settings > Bluetooth & Devices > Wheel.
  • This update improves the persistence of Fluid Dictation setting in voice typing.
  • This update improves the reliability of keyboard navigation for emoji panels (Windows logo key + Period).
  • This update improves the reliability of typing when using the ADLaM keyboard.
• [Sharing] New! Drag Tray is now called Drop Tray. Its settings are now under Settings > System > Multitasking (previously Nearby sharing). Drop Tray uses a smaller peek view. This improvement helps prevent the Drop Tray from opening unintentionally and makes it easier to dismiss when you work near the top of the screen.
  
• [Introducing Agents on Taskbar] New! Windows is adding a new way to monitor your agents from the taskbar. This experience supports agents across first- and third-party apps, with Researcher in the Microsoft 365 Copilot app as the first adopter. When Researcher works on a report, Windows shows progress on the taskbar so you can check updates at a glance. Hover over the Microsoft 365 Copilot icon to see real-time progress. When the report is ready, Windows notifies you. Select the notification or the icon to return to the app and review and use the results.
  
  • Developers can learn how to use this API with the Windows.UI.Shell.Tasks API.
• [Enterprise State Roaming (ESR)] New! ESR can now be managed through Windows Backup for Organizations policies. This makes setup easier for IT administrators. To learn more, see Enterprise State Roaming.
  
• [Policy-Based Removal of Preinstalled Microsoft Apps] New! This update adds support for a dynamic app removal list to the "Remove Default Microsoft Store packages" policy for Windows Enterprise and Education. Administrators can remove additional MSIX/APPX-packaged apps by specifying their app package family names using Group Policy. The dynamic list is not currently available in Intune Settings Catalog. Validation must be performed using Group Policy or custom OMA-URI. For more information, see Policy-based in-box app removal.
  
• [Printing] New! This update adds a new icon to show where a printer supports Windows Protected Print Mode in print settings.
  
• [Windows Driver Policy update] New!  This update improves Windows security by changing how the Windows kernel trusts third‑party drivers. Default trust for cross‑signed drivers is removed, while drivers from the Windows Hardware Compatibility Program (WHCP) and an allow list of trusted legacy drivers remain allowed. Windows audits driver compatibility for at least 100 hours and three reboots before enabling enforcement. After enforcement, a small number of cross‑signed drivers might be blocked. For more information, see the Windows driver policy and the Advancing Windows driver security blog.
  
• [Enhanced security and performance for batch files] New!  Administrators and Application Control for Business policy authors now have additional control over how the system processes batch files and Command Prompt (CMD) scripts. Starting with this release, administrators can enable a more secure processing mode for batch files. This mode prevents batch files from changing during execution.
  
  • To enable this setting, add the following value to the registry:
  • Registry Key: HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor
  • Value name: LockBatchFilesWhenInUse
  • Type: DWORD
  • Data to be set: 0 (disabled) or 1 (enabled)
  • Policy authors can also enable this mode by using the LockBatchFilesWhenInUse application manifest control, as documented in the Application Control for Business manifest schema.

  • The size limit for formatting FAT32 volumes from the command line from 32GB to 2TB.
• [Delivery Optimization] This update improves memory usage, reducing likelihood it will use an unexpectedly large amount of memory.
  
• [Display and graphics] This update improves persistence and availability of color profile options for supported monitors.
  
• [Kiosk mode] This update simplifies configuration for allowed packaged apps in kiosks when Microsoft Edge is one of the allowed apps.
  
• [General Performance] This update improves the performance of launching startup apps after starting your device (apps listed under Settings > Apps > Startup).
  
• [General Reliability] This update brings underlying changes to help improve explorer.exe reliability, including at sign‑in, when interacting with taskbar menus and Task View, when unpinning items from File Explorer's Quick Access, and more.
