Microsoft released update KB5094126 on June 9, 2026, for Windows 11 versions 24H2 and 25H2 to improve shell responsiveness. This update introduces the Low Latency Profile, which temporarily boosts CPU frequency for one to three seconds during interactions with system features like the Start menu and taskbar, resulting in system flyouts opening up to 70% faster and core applications launching up to 40% quicker. The update also includes features such as Shared Audio for simultaneous audio use by two users, enhanced Windows Task Manager with NPU usage columns, the ability for multiple applications to access the same camera stream, improved Windows Search for locating files with two characters, a refined installation process allowing custom user folder names, and optimizations to Windows Hello for authentication methods. The update also addresses over 200 security vulnerabilities.
