This update gives you more ways to customize the taskbar to match how you work and make better use of screen space. New! You can now choose whether the taskbar appears at the bottom, top, left, or right side of your screen. In these other positions, tooltips, flyouts, and animations will still come from the taskbar, and most customization settings, such as never combining taskbar icons, will work with all locations. Search box and smaller taskbar are currently supported only for top and bottom positions. To change the position of the taskbar, go to Settings > Personalization > Taskbar > Taskbar behaviors > Taskbar position New! A smaller taskbar option is now available to help maximize screen space on smaller devices. This experience reduces the size of taskbar icons and the taskbar height while maintaining access to key features such as Start, Search, and the system tray. To change your taskbar size, go to Settings > Personalization > Taskbar > Taskbar behaviors > Taskbar size. When set to Small, both the icons and the taskbar height become smaller. New! The Taskbar behaviors section of the Taskbar settings page is now expanded by default for improved discoverability. This update improves reliability of loading the system tray area of the taskbar for non-touch PCs. Start menu This update makes the Start menu more personal with several customizations. New! You can choose between a small or large Start menu, in addition to "Automatic (default)" that's available today. To customize this, go to Settings > Personalize > Start > Start menu size. New! The "Recommended" section is renamed "Recent" in the Start menu and Settings page (Settings > Personalize > Start). New! You can now hide your name and profile picture in Start by going to Settings > Personalize > Start > Hide your name and profile picture on Start. New! The Start menu settings page is now redesigned with section-level toggles to independently show or hide Pinned, Recommended, and All. Windows Search This update includes improvements that make Windows Search more dependable, easier to scan, and clearer before you click. New! Search home has been simplified to reduce visual clutter and make it easier to get back to recent searches quickly. New! Search does a better job showing where a result comes from—app, setting, file, web result, or Store suggestion—so it’s easier to tell what you’re looking at and where you will go before you click. New! A new setting in Settings > Privacy & Security > Search lets you choose whether web and Microsoft Store suggestions appear alongside local results. New! Windows now automatically indexes your most used folders to make those files appear in subsequent search results. You can control the setting at Settings > Privacy & Security > Search > Automatically find additional relevant locations File Explorer New! Launching File Explorer Home is now faster and more responsive. New! The Recommended section on Home now supports touch scrolling, making it easier to browse files in the carousel. General design This update improves the reliability of navigating to and interacting with Settings > System > Display. This update improves the persistence of previous brightness settings once the energy saver turns off. Task Manager This update streamlines the experience for selecting a secondary keyboard during Windows setup, making it easier to skip when it isn't needed. This update improves the Get Started app with new App install, Site pinning, and Theme pages to help you personalize your device and discover new features.

Microsoft released Windows 11 cumulative updates KB5124008 and KB5122880, which serve as mandatory security patches and feature additions for versions 25H2/24H2 and 23H2. These updates incorporate the September 2026 Patch Tuesday security fixes addressing one thousand vulnerabilities discovered in previous months. The changes are identical across both Windows 11 versions, ensuring consistent security and functionality across supported operating systems. In terms of user interface enhancements, the update introduces significant customization options for the taskbar, allowing users to position it at the bottom, top, left, or right of the screen. Furthermore, a smaller taskbar option is available to maximize screen real estate on smaller devices, reducing icon and height while retaining essential functions like Start, Search, and the system tray. The Taskbar behaviors section has also been expanded by default for improved discoverability. The Start menu received personalization improvements, including the ability to select between small, large, or automatic sizes, renaming the Recommended section to Recent, and offering an option to hide the user's name and profile picture. The Windows Search functionality was enhanced to improve reliability and clarity, featuring a simplified search home for reduced visual clutter and improved contextual feedback on where search results originate, such as app, file, or web sources. Users now have granular control over where web and Microsoft Store suggestions appear in relation to local results, and the system automatically indexes frequently used folders to enhance search relevance. File Explorer also received performance upgrades, making the launch of File Explorer Home faster and more responsive, and the Recommended section supports touch scrolling for easier browsing within the file carousel. General design improvements were implemented through updated progress indicators across various operational stages, including startup, sign-in, and updates, aiming for a more modern experience. Regarding system security, administrator protection was introduced to enable just-in-time privileges, protecting floating administrative rights against elevation-of-privilege attacks through profile separation. Switching between virtual desktops has been made smoother and more responsive. Furthermore, the update improves the persistence of previous brightness settings when energy saver modes are activated, and reliability in navigating the Settings area has been improved. Updates to system processes and application support also occurred: the update introduces enhanced coordination for application updates with Windows Update through the Windows Update Orchestration Platform, providing a streamlined experience for participating applications. In the Microsoft Store context, the update supports in-app purchases within packaged WinUI 3 applications requiring elevation, integrating them with Microsoft's commerce platform. A critical technical advancement involves the introduction of Process Isolation for Microsoft Execution Containers (MXC), which establishes a lightweight boundary using Windows operating-system containment capabilities to restrict access to resources like files, networking, and the user interface according to policy. Additionally, preview platform support is introduced for tagging agentic processes, allowing authorized components to assign an opaque agent identifier that is automatically passed to child processes during authentication via Web Account Manager (WAM). |
