What’s new in the KB5094126 Cumulative Update for Windows 11
The KB5094126 update released on June 9, 2026, includes new features and quality improvements that were part of the KB5089549 update released on May 12, 2026, and KB5089573 released on May 26, 2026. Here are some of the exciting new features and improvements.
- Bitlocker Recovery Issues: Improves startup reliability after boot file updates, so devices start normally without entering BitLocker recovery.
- Connectivity: This update improves the reliability of Simple Service Discovery Protocol (SSDP) notifications to help prevent the service from becoming unresponsive.
- File Explorer: This update expands the list of archive formats that can be used in File Explorer to include uu, cpio, xar, and NuGet Packages (nupkg). The view and sort preferences are preserved in folders such as Downloads and Documents when apps launch File Explorer directly to those locations. The update eliminates a white flash that might occur when opening “This PC” or resizing the Details pane in dark mode. Additionally, it enhances the reliability of explorer.exe processes, ensuring they terminate properly after closing File Explorer windows.
- Secure Boot: The status of Secure Boot certificate updates on your device may be displayed in the Windows Security app (Settings > Privacy & security > Windows Security). This update addresses an issue where the device might enter BitLocker Recovery after the Secure Boot updates. With this update, Windows quality updates include additional high confidence device targeting data, increasing coverage of devices eligible to automatically receive new Secure Boot certificates. Devices receive the new certificates only after demonstrating sufficient successful update signals, maintaining a controlled and phased rollout.
- Networking: This update improves reliability when Windows uses SMB compression over QUIC. After you install this update, SMB compression requests over QUIC complete more consistently, reducing the likelihood of timeouts and supporting smoother, more dependable performance.
- Remote Desktop: This update enhances protection against phishing attacks involving Remote Desktop (.rdp) files. Upon opening an .rdp file, Remote Desktop displays all requested connection settings before establishing a connection, with each setting disabled by default. Additionally, a one-time security warning is shown the first time an .rdp file is opened on a device.
- Reset this PC: KB5094126 cumulative update addresses an issue that might cause device reset to fail when using the “Keep my files” or “Remove everything” options. This might occur after installing the March 2026 (KB5079420) Hotpatch security update.
- Gaming Mode: The new Xbox Mode is now available on Windows 11 PCs, including laptops, desktops, and tablets. Drawing inspiration from the Xbox console experience, this mode delivers a sleek, full-screen interface that prioritizes your games and reduces background distractions.
- Haptic Feedback Effects: Haptic feedback effects are available on compatible input devices during specific actions, like aligning objects in PowerPoint or snapping and resizing windows. These haptic signals can be turned on or off in Settings > Bluetooth & devices > Mouse, Touchpad, or Pen > Haptic signals.
- Sharing: Drag Tray has been renamed to Drop Tray. Its settings are now under Settings > System > Multitasking (previously Nearby sharing).
- New Agents on Taskbar: Windows is adding a new way to monitor your agents from the taskbar. This feature enhances support for agents across both first- and third-party applications, with the Microsoft 365 Copilot app’s Researcher tool leading the way as the initial adopter.
- Enterprise State Roaming (ESR): ESR can now be managed through Windows Backup for Organizations policies.
- Policy-Based Removal of Preinstalled Microsoft Apps: KB5083631 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.
- Update for Windows Driver Policy: 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 allowed list of trusted legacy drivers remain allowed.
- Enhanced security and performance for batch files: Administrators and Application Control for Business policy authors now have additional control over how the system processes batch files and Command Prompt (CMD) scripts.
- Improved Voice Typing: The voice typing on the touch keyboard now looks simpler and more intuitive. The update also adds the Arabic 101 Legacy keyboard layout to the list.
- New Shared Audio: This feature enables two people to listen to the same audio from a single Windows 11 PC at the same time. It uses Bluetooth® LE Audio broadcast technology to make sharing easy.
- Magnifier: Magnifier provides clearer and more consistent announcements when working with a screen reader. It also supports magnification of permitted protected content.
- Task Manager: Task Manager now provides enhanced insight into NPU usage on PCs equipped with an NPU. New optional columns, including NPU and NPU Engine, are available on the Processes, Users, and Details pages. This update improves the CPU speed display on the Performance page of Task Manager for VMs.
- Camera Improvements: Windows 11’s Multi-App Camera feature lets multiple apps use your camera simultaneously. The Basic Camera mode provides a simplified camera setup, helpful for troubleshooting or enhancing stability if your camera encounters issues.
- Windows Setup: You can now choose a custom name for your user folder on the Device Name page during Windows setup. The updated experience makes it easier to select a custom name during setup only. If this step is skipped, Windows uses the default folder name and continues setup as usual.
- Performance Improvements: This update accelerates app launch and core shell experiences such as the Start menu, Search, and Action Center.
- Windows Hello: The update optimizes the Windows Biometric service (WinBio) and improves sign‑in behavior on the lock screen and sign‑in screen.
- Windows Search Box: Windows Search will now find and prioritize files with as few as two characters.
- USB Improvements: This update improves reliability for displays attached to USB4 docks and hubs.
- Sensors: This update improves resiliency against apps that could keep the sensor hub powered on and drain power, impacting battery life.
- HID Improvements: This update improves battery life related to the HID and input stack for failed HID devices.
- Reliability: This update enhances Windows reliability on the sign-in and lock screens, in File Explorer, with touch gestures on touchscreen devices, and when adjusting themes in Settings.
- Microsoft Store: With this update, the download performance and bandwidth usage of the MS Store have been improved.
- Input: The KB5094126 update significantly improves the reliability of the touch keyboard on the sign‑in screen, the reliability of explorer.exe when closing the input switcher, and performance when opening or navigating to clipboard history.

Patching KB5094126 update via WSUS/SCCM
Organizations that rely on WSUS or Configuration Manager to distribute software updates to on-premise devices can deploy the KB5094126 update efficiently. If you don’t see the update either in WSUS or SCCM, you must manually import the update into WSUS.
In the below image, I have successfully imported the KB5094126 update into WSUS. If you’re using WSUS standalone in your setup, right-click the update and approve it. I suggest rolling out the update to a group of pilot devices initially, and once confirmed that the update causes no issues, proceed to deploy it across all Windows 11 devices. The deployment occurs based on the schedule you’ve configured.
To patch the same update using Configuration Manager, ensure you open the console and synchronize the software updates. This will display all the latest updates from WSUS, including those you manually imported into the console.
Once the sync is complete, go to Software Library > Software Updates > All Software Updates. In the search bar, type “KB5094126” and click search. You should now see the update 2026-06 Cumulative Update for Windows 11, version 25H2 for x64-based Systems (KB5094126) (26200.8655) listed in the console. From here, you can refer to the SCCM patching guide to deploy it to your Windows devices.
