Windows 11 KB5083631 update released with major explorer.exe reliability upgrades, AI agent support, Xbox mode, and more

Microsoft has released Windows 11's optional non-security preview update for April 2026, which includes a number of new improvements and changes designed to make the OS more reliable and easy to use. The update, marked KB5083631, is now available and includes the new Xbox mode that was announced as generally available earlier today, along with reliability improvements to explorer.exe, a new haptic feedback engine, an updated drop tray share menu, support for AI agents on the Taskbar, and more.

It's a big quality of life update that includes a lot of changes that many users will appreciate. File Explorer is gaining several improvements tied to the explorer.exe reliability updates, including the removal of the annoying white flash bug in dark mode, and support for more archive formats such as uu, cpio, xar, and NuGet Packages (nupkg).

The explorer.exe improvements also tackle reliability across the system, "including at sign‑in, when interacting with taskbar menus and Task View, when unpinning items from File Explorer’s Quick Access, and more." These improvements are part of Microsoft's big Windows K2 effort designed to fix up the OS and address feedback from users.

The new haptic feedback engine provides subtle vibrations when interacting with certain elements of the system such as the close button on app windows or snapping apps side by side. This new feature requires specific hardware, but it's a great quality of life addition for those with the necessary hardware support.

This update also introduces support for AI agents on the Taskbar. If you don't like AI, don't worry, as this isn't adding AI to the OS. Instead, it's introducing a set of APIs for AI developers to tap into so that they can more easily showcase their AI tools to end users on Windows. If you don't use AI tools on Windows, this update will not do anything to change that.

There are plenty of other improvements to note as well, including faster and more reliable Windows Hello authentication, a more intuitive voice typing feature, and more. The entire changelog is available below, and all features mentioned are rolling out in waves once the update is installed. To get the features faster, make sure you have the "Get the latest updates as soon as they're available" toggle enabled in Windows Update.

Windows 11 KB5083631: What's new?

• [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.
