Microsoft has released a new optional preview update for Windows 11 on April 30, 2026. The update — KB5083631 — applies to both Windows 11 version 24H2 and version 25H2, bumping OS builds to 26100.8328 and 26200.8328 respectively.

This is a non-security preview update, which means it’s an optional release that previews quality improvements ahead of the next Patch Tuesday. It covers a wide range of areas including gaming, File Explorer, input methods, taskbar features, printing, and important enterprise tools. Here’s a full breakdown of everything in KB5083631.

⚠️ Important Notice: Secure Boot Certificate Expiration

Before diving into the new features, Microsoft has flagged a critical issue included in this update’s announcement. Secure Boot certificates used by most Windows devices are scheduled to expire starting in June 2026. If your device isn’t updated in time, it could affect its ability to boot securely.

Microsoft strongly recommends reviewing their Secure Boot certificate expiration guidance and taking action before June 2026 to avoid disruption. This applies to both personal and business devices.

What’s New in Windows 11 KB5083631 — Full Feature Breakdown

KB5083631 is packed with new features and improvements. Below is a detailed look at each change area.

🎮 Gaming — Xbox Mode Comes to Windows 11 PCs

This is arguably the biggest headline of KB5083631. Microsoft has introduced Xbox Mode to Windows 11 PCs, including laptops, desktops, and tablets. Inspired by the Xbox console experience, Xbox Mode provides a streamlined, full-screen interface that puts your games front and centre while minimising background distractions.

Xbox Mode is designed for moments when you want to lean back, pick up a controller, and focus entirely on your game. You can enter Xbox Mode from:

• The Xbox app
• Game Bar settings
• The keyboard shortcut Windows logo key + F11

This is a significant move by Microsoft to bridge the gap between console and PC gaming, making Windows 11 feel much more like a full gaming platform.

📁 File Explorer — New Archive Formats, Better Preferences, Dark Mode Fix

File Explorer gets several meaningful improvements in this update:

• New archive format support — File Explorer can now work with additional archive formats: uu, cpio, xar, and NuGet Packages (.nupkg). This is particularly useful for developers working with package management.
• View and Sort preferences preserved — Your view and sort settings in folders like Downloads and Documents will now persist when apps open File Explorer directly to those locations. No more constantly resetting your preferred view.
• Dark mode white flash fix — A white flash that appeared when opening “This PC” or resizing the Details pane in dark mode has been removed. A small but noticeable quality-of-life improvement for dark mode users.
• Improved reliability — Explorer.exe processes now correctly stop after File Explorer windows are closed, preventing potential background resource usage.

⌨️ Input — Haptic Feedback, New Voice Typing Design, Arabic Layout

Input gets a notable set of improvements in this release:

• Haptic feedback for compatible devices — You can now feel haptic feedback effects when performing certain actions like aligning objects in PowerPoint or snapping and resizing windows. Supported devices currently include the Surface Slim Pen 2, ASUS Pen 3.0, MSI Pen 2, and select mice like the Logitech MX Master 4 (pending hardware partner updates). This can be toggled under Settings > Bluetooth & Devices > Mouse, Touchpad, or Pen > Haptic Signals.
• Redesigned voice typing — Voice typing on the touch keyboard now has a cleaner, less intrusive design. The full-screen overlay is gone and voice typing animations now display directly on the dictation key, keeping you focused while you dictate.
• Arabic 101 Legacy keyboard layout — The classic Arabic 101 keyboard layout is now available for users who prefer the pre-AltGr design. It can be added under Settings > Time & Language > Language & Region.
• Other input reliability fixes — Improvements to custom tool settings under the Wheel settings page, better persistence of the Fluid Dictation setting in voice typing, improved emoji panel keyboard navigation, and fixes to typing reliability when using the ADLaM keyboard.

📤 Sharing — Drag Tray Renamed to Drop Tray, Smarter Behaviour

The feature previously known as “Drag Tray” has been officially renamed to Drop Tray, and it comes with some welcome refinements. Its settings have moved to Settings > System > Multitasking (previously under Nearby Sharing). Drop Tray now uses a smaller peek view, which helps prevent it from opening accidentally when you’re working near the top of your screen and makes it easier to dismiss when not needed.

🤖 Agents on Taskbar — Monitor AI Tasks Without Switching Apps

Windows 11 is getting a new way to monitor AI agent activity directly from the taskbar. When an agent is working on a task — such as Researcher in the Microsoft 365 Copilot app generating a report — Windows will now display real-time progress on the taskbar icon. You can hover over the app icon to see progress at a glance, and Windows will notify you when the task is complete.

Microsoft 365 Copilot’s Researcher agent is the first app to support this, with more first- and third-party apps expected to adopt it over time. Developers can integrate this experience using the Windows.UI.Shell.Tasks API.

🏢 Enterprise Features — ESR via Windows Backup Policy, App Removal Policy Expanded

There are two notable additions for IT administrators and enterprise environments in this update:

• Enterprise State Roaming (ESR) via Windows Backup for Organizations — ESR can now be managed through Windows Backup for Organizations policies. This simplifies configuration for IT administrators who manage large fleets of devices, removing the need for separate Azure AD-based ESR setup in many scenarios.
• Expanded Policy-Based App Removal — The “Remove Default Microsoft Store Packages” Group Policy now supports a dynamic app removal list for Windows Enterprise and Education editions. Administrators can specify additional MSIX/APPX-packaged apps to remove by providing their app package family names via Group Policy or custom OMA-URI. Note this is not yet available in the Intune Settings Catalog.

How to Install KB5083631

Since KB5083631 is an optional preview update, it won’t install automatically. You need to manually check for it:

1. Open Settings and go to Windows Update.
2. Click “Check for updates”.
3. Look for KB5083631 under “Optional updates available” or “Advanced options > Optional updates”.
4. Select it and click “Download and install”.
5. Restart your PC when prompted to complete the installation.

If you don’t see it immediately, don’t worry — Microsoft is using a gradual rollout, so it may take a few days to appear for all eligible devices running Windows 11 24H2 or 25H2.

💡 Note: This update is being rolled out in phases. The gradual rollout means some devices receive it before others. The broad “normal rollout” will follow once the update is validated across a wider range of devices.

Which Windows 11 Versions Does KB5083631 Apply To?

KB5083631 applies to Windows 11 version 24H2 and Windows 11 version 25H2 only. It does not apply to older versions like Windows 11 23H2, 22H2, or 21H2.

If you’re running an older version of Windows 11, you won’t receive this update. Windows 11 23H2 is still receiving security updates but no longer receives new optional preview features. Windows 11 22H2 has already reached end of servicing.

If your PC is still running Windows 10 and you’d like to upgrade to Windows 11 Pro to stay current, you can get a genuine Windows 11 Pro license key from WinCDKey at a great price and receive all future updates including this one.
