What Microsoft shipped in the June 2026 updates (KB5094126, KB5093998)
Microsoft released two cumulative updates for Windows 11 on Patch Tuesday in June 2026: KB5094126 for 25H2/24H2 and KB5093998 for 23H2. The release is mandatory because it contains the June 2026 Patch Tuesday security patches for several vulnerabilities discovered in previous months. The builds change to 26200.8457 (25H2), 26100.8457 (24H2), and 22631.7079 (23H2). This is the sixth Patch Tuesday release in 2026; it is based on 24H2, which means 25H2 receives the same fixes and there are no exclusive changes between those two branches.
You can install the update from Start > Settings > Windows Update by clicking “Check for Updates,” or download and install manually from the Microsoft Update Catalog.
New and visible features: Shared Audio, Magnifier, Xbox mode and camera changes
Several user-facing features arrive in this package. Shared Audio uses Bluetooth® LE Audio broadcast technology so two people can listen to the same PC audio at once; users start sharing by opening Quick settings from the taskbar, selecting Shared Audio, choosing two supported paired and connected devices, and selecting Start sharing. Xbox mode is now available on more PCs, offering an Xbox console–like experience on a PC.
Magnifier improvements include clearer and more consistent announcements for screen‑reader users (zooming, view switching, color inversion and Magnifier on/off), support for magnification of permitted protected content, and smoother movement in lens mode. Windows 11’s Multi‑App Camera feature lets multiple applications access the camera stream simultaneously and Basic Camera mode provides a simplified camera experience for troubleshooting and stability; administrators can set these modes via Group Policy under Computer Configuration > Administrative Templates > Windows Components > Camera > Configure Camera Options.
Task Manager, system performance, storage and input reliability
Task Manager gains detailed NPU telemetry: optional NPU and NPU Engine columns on Processes, Users, and Details pages, plus NPU Dedicated Memory and NPU Shared Memory on the Details page. Neural engines that are part of a GPU will now appear on the Performance page. A new optional Isolation column shows which apps run in an AppContainer. The update also fixes an issue where CPU speed display could show unexpectedly high numbers in VMs after resuming from hibernate.
General shell and app-launch performance are improved, and personalization changes boost color selection accuracy for accents and wallpaper persistence across restarts and upgrades. Storage updates include Dev Drive creation and resizing with size specified in gigabytes (GB) and a change so Settings > System > Storage prompts UAC only when the user chooses to view temporary files.
Input and device reliability fixes cover USB (improved behavior for displays on USB4 docks and additional resiliency in the USB3 stack), sensor hub power resiliency to prevent battery drain, improved HID power hygiene for failed HID devices, better touch‑keyboard reliability on the sign‑in screen, and improved explorer.exe reliability when closing the input switcher. Clipboard-history navigation performance and desktop shortcut loading reliability are also addressed.
Windows Hello, search, fonts, and Microsoft Store updates
Windows Hello changes optimize the Windows Biometric service (WinBio) to improve resume-from‑Modern‑Standby performance, reduce unexpected authentication blocks by resolving missing secure enrollment metadata, and change sign‑in behavior so face or fingerprint is the default sign‑in method when set up and available. If a user intentionally uses a PIN three times in a row, Windows will continue using the PIN until another method is chosen.
Windows Search will now find and prioritize files with as few as two characters. The Times New Roman font family was updated to correct combining diacritical mark rendering across Greek and Cyrillic scripts. Microsoft Store changes include underlying improvements for download performance and bandwidth usage plus better error reporting when downloads fail due to Windows Update group policy settings.
What this means for technologists, enterprise admins, and end users
- Technologists and security teams: This mandatory Patch Tuesday exposes a set of system, USB, input, and biometric fixes you’ll want to validate in staging—installation can be performed via Windows Update or the Microsoft Update Catalog.
- Enterprise administrators: Group Policy controls for Camera modes and the UAC behaviour in Storage settings are explicit changes to note for deployment and user-support workflows.
- End users: Expect faster app launches, more resilient sign‑in behavior with Windows Hello, and new conveniences such as Shared Audio and broader Xbox mode availability on supported PCs.
Microsoft reports it is not aware of any new issues with this month’s Patch Tuesday release, noting the update is not a massive release compared to previous patches. The company also confirmed it is working on a larger Windows 11 2026 quality update that will restore the movable taskbar, significantly improve modern interface performance (including the right‑click menu), limit Copilot integration, reduce ads, and make the out‑of‑the‑box experience faster with skippable Windows Updates.
