The Windows 11 June update (KB5094126) landed on 9 June 2026 as part of Microsoft’s regular Patch Tuesday cycle — but this month’s release is anything but routine. Beyond patching 206 vulnerabilities, it ships several features that genuinely change how the OS feels and functions day to day. This guide cuts through the noise and focuses on the improvements that matter to real users.
What Is the Windows 11 June Update 2026?
KB5094126 is the cumulative update for Windows 11 versions 25H2 and 24H2, released on 9 June 2026. It applies to OS Builds 26200.8655 and 26100.8655. While the headline news is always the security patch count, this particular release is notable because Microsoft bundled several quality-of-life and performance improvements that had been previewed in the optional May 2026 update (KB5089573) — meaning more users are now getting them for the first time via the standard update channel.
Low Latency Profile: The June 2026 Windows Update’s Biggest Win
The most impactful feature in this Windows 11 update is the Low Latency Profile, and it’s enabled by default on eligible hardware. In simple terms, when you click the Start menu, open a context menu, or launch an app, the CPU now spikes instantly to its maximum frequency rather than gradually ramping up. The result is a noticeable reduction in that split-second hesitation that has always made Windows feel slightly behind iOS or macOS for quick interactions.
According to independent testing reported by Windows Latest, Low Latency Profile targets the mismatch between user input and CPU frequency scaling — the small waits that make an otherwise powerful PC feel sluggish. For users on Windows 11 25H2, the feature is enabled automatically. Those on 24H2 may need to verify their build number and check for the update manually.
-
Who benefits most: Anyone who finds the Start menu or File Explorer feel slightly laggy
-
Hardware requirement: Applies to most modern multi-core processors; no dedicated NPU required
-
How to confirm it’s active: Check your OS build is 26200.8655 or 26100.8655 via Settings > System > About
Shared Audio via Bluetooth LE — a Genuinely Useful New Feature
One of the standout additions in the Windows 11 June update features list is Shared Audio. Borrowing a concept familiar to iPhone users, this feature lets two people connect separate Bluetooth headphones to a single Windows 11 PC and listen to the same audio simultaneously — without a splitter cable or third-party software.
It relies on Bluetooth LE Audio broadcast technology. Both headsets need to support Bluetooth LE Audio, which is increasingly common on headphones released in 2024 and 2025. For co-workers sharing a desk, couples watching a film on a laptop, or anyone who has ever searched their bag for a headphone splitter, this is a genuinely practical addition. The setup lives in Settings > Bluetooth & devices, where you’ll see the new shared audio pairing option once the update is installed.
Multi-App Camera Support: Finally Fixed
Before this update, only one application could access the webcam at a time on Windows 11. If Microsoft Teams had the camera, OBS didn’t. If Zoom was running, your screen-recording tool was out of luck. The June 2026 Windows update resolves this longstanding frustration by allowing multiple apps to access the same camera feed simultaneously.
This is a meaningful productivity upgrade for anyone who regularly video calls while also running screen capture tools, virtual backgrounds, or AI-powered camera enhancement apps. Microsoft achieves this through a new camera sharing layer in the OS, which mediates access rather than locking the hardware to a single application.
-
Works with built-in and USB webcams
-
Compatible with Teams, Zoom, OBS Studio, and other camera-dependent apps
-
No additional configuration required — the OS handles mediation automatically
NPU Monitoring in Task Manager
As AI-accelerated PCs — particularly those bearing the Copilot+ label — become more common, the June 2026 Windows update adds NPU (Neural Processing Unit) columns to Task Manager. You can now monitor which applications are using your NPU and how heavily it’s being utilised, right alongside CPU, GPU, and RAM data.
This isn’t a feature most casual users will interact with daily, but it’s an important step toward transparency. As more apps offload tasks like background blur, noise cancellation, and local AI inference to the NPU, being able to diagnose performance issues or identify resource hogs becomes genuinely useful. Think of it as the GPU performance overlay that Task Manager added years ago, now extended to the newest class of silicon.
Windows 11 Update Features: What’s Cosmetic vs. What’s Real
Not every change in a monthly update is a game-changer. It’s worth being honest about which Windows 11 update features in June 2026 are meaningful and which are polish:
Meaningful changes
-
Low Latency Profile — tangible improvement in UI responsiveness, every single session
-
Multi-App Camera — eliminates a real daily workflow blocker for video professionals
-
Shared Audio — genuinely useful for specific scenarios, no workaround needed anymore
-
NPU Task Manager columns — important for diagnosing AI workload performance
More cosmetic or niche
-
Magnifier accessibility improvements — welcome, but affects a narrow audience
-
OOBE (Out of Box Experience) refinements — only seen once during setup
-
Secure Boot certificate updates — security-critical but invisible in daily use
The honest take: this is one of the stronger feature drops Microsoft has shipped in a regular Patch Tuesday. The Low Latency Profile alone makes the June 2026 update worth installing promptly, rather than delaying as some users habitually do.
Windows 11 KB5094126: How to Get the Update
Installing the Windows 11 KB5094126 update is straightforward:
-
Open Settings and navigate to Windows Update
-
Click Check for updates — the update will appear if you’re on version 24H2 or 25H2
-
Download and install; a restart will be required to apply the full update
-
After restart, confirm your build number under Settings > System > About — you should see Build 26100.8655 (24H2) or 26200.8655 (25H2)
If you’re still on Windows 11 23H2, you will receive the security patches but not all the new features listed here. Microsoft is nudging users toward 24H2 and beyond for the complete experience.
Not on Windows 11 Yet? Here’s What You’re Missing
Users still running Windows 10 or an older version of Windows 11 are increasingly missing out as each update raises the feature floor. Windows 10 reaches end of support in October 2025, meaning no further security patches after that date — making the upgrade case even stronger.

Frequently Asked Questions
What is the Windows 11 June update 2026 KB number?
The main June 2026 Patch Tuesday update for Windows 11 is KB5094126, applying to OS Builds 26200.8655 (version 25H2) and 26100.8655 (version 24H2). It was released on 9 June 2026 and is available via Windows Update as a standard cumulative update.
Is the Low Latency Profile enabled automatically?
Yes, on Windows 11 version 25H2, the Low Latency Profile is enabled by default once KB5094126 is installed. On 24H2, behaviour may vary; some users report it rolling out gradually. You can check your build number under Settings > System > About to confirm the update is applied.
Do I need special hardware for Shared Audio?
Both Bluetooth headphones used in a Shared Audio session must support Bluetooth LE Audio broadcast technology. This standard became widespread on consumer headphones from 2024 onwards. Your PC also needs a Bluetooth adapter that supports LE Audio — most systems sold from 2022 onward qualify.
Will Multi-App Camera work with my specific apps?
Multi-App Camera support works at the OS level, so it is broadly compatible with any application that requests camera access through standard Windows APIs — including Teams, Zoom, Google Meet, OBS Studio, and similar tools. Apps that use proprietary or legacy camera access methods may behave differently; checking for app updates is always advisable after a major OS change.
Can I install the June 2026 update on Windows 11 23H2?
You will receive the security-focused patches on 23H2, but several new features — including the Low Latency Profile and NPU Task Manager columns — are tied to 24H2 and 25H2. Microsoft recommends upgrading to the latest version to receive the full feature set, and the upgrade is free via Windows Update for eligible devices.
