If you’ve ever experienced a delay when clicking the Start button on your Windows 11 device, you are not alone. Microsoft is addressing this common frustration with its recent update, KB5094126, released on June 9, 2026, for Windows 11 versions 24H2 and 25H2. This update aims to enhance shell responsiveness, a concern that has lingered since the operating system’s debut in 2021. A key feature of this update is the introduction of the Low Latency Profile.
What is Low Latency Profile and why does it matter?
The Low Latency Profile, which was initially tested in a preview build on May 26, has now been rolled out more broadly. This innovative feature temporarily boosts the CPU frequency to its peak for a brief period of one to three seconds. This spike in performance is triggered during interactions with essential system features such as the Start menu, Search, Action Center, and taskbar flyouts.
This short-lived performance enhancement is designed to ensure that users experience immediate responsiveness, significantly reducing wait times. For instance, system flyouts can open up to 70% faster, while core applications may launch up to 40% quicker compared to previous builds. These improvements are particularly beneficial for older or lower-spec machines that have struggled to meet the demands of Windows 11’s hardware requirements.
What else is new in the June update?
The June update also introduces several other noteworthy features. Shared Audio now allows two users to enjoy audio from a single Windows 11 PC simultaneously through Bluetooth LE Audio. Additionally, the Windows Task Manager has been enhanced with new NPU usage columns, providing clearer insights into how the neural processing unit is utilized during on-device AI tasks.
Moreover, multiple applications can now access the same camera stream at once, enhancing collaborative capabilities. Windows Search has also seen improvements, enabling users to locate local files with just two characters, a change that streamlines daily tasks. The installation process has been refined as well, allowing users to select a custom user folder name during setup. Lastly, Windows Hello has been optimized to reliably revert to face or fingerprint sign-in methods after alternative authentication attempts.
It is advisable for users to proceed with this update, as it also includes the June 2026 Patch Tuesday fixes, addressing over 200 security vulnerabilities, ensuring a safer computing experience.
