Microsoft has released preliminary update KB5095091 (Build 28000.2340) for Windows 11 version 26H1. The update is intended for PCs with ARM64 architecture processors (Snapdragon), as well as for devices with x64 architecture processors (Intel and AMD). This release includes new features and improvements, including AI-based capabilities, platform development, and performance enhancements.
- Screen Magnifier. Now provides clearer and more consistent notifications when working with Narrator. Voice prompts accompany zooming in and out, switching modes, enabling and disabling color inversion, as well as turning the magnifier itself on and off. Added support for magnifying protected content with permissions. Improved smoothness of movement in Lens mode.
- Task Manager. Expanded capabilities for monitoring NPU load. Added optional columns NPU and NPU Engine on the Processes, Users, and Details tabs, as well as columns NPU Dedicated Memory and NPU Shared Memory on the Details tab. Neural engines within GPUs are now displayed on the Performance tab. A new optional Isolation column on the Processes and Details tabs shows which applications are running in AppContainer. You can add any of the new columns via the column header context menu. Fixed CPU frequency display on the Performance tab in virtual machines after resuming from hibernation — inflated values are no longer shown.
- Camera. The Multi-App Camera feature allows multiple applications to access the camera video stream simultaneously. Basic Camera mode enables simplified functionality for troubleshooting or improving stability. Organization administrators can now set these modes via group policy under Computer Configuration > Administrative Templates > Windows Components > Camera > Configure camera settings.
- Windows Setup. You can now choose a custom user folder name on the Device Name page during setup. The updated interface simplifies name selection, but only during the setup process. If this step is skipped, Windows uses a default folder name. Folder names must comply with standard Windows naming rules.
- General Performance. Accelerated launch of applications and core shell elements — Start menu, search, and Action Center.
- Personalization. Improved accuracy of accent color matching to the desktop wallpaper when automatic accent color selection is enabled. Increased reliability of wallpaper preservation between reboots and system updates, including enhanced support for high-resolution wallpapers — this prevents rollback to a solid color background.
- Windows Hello. Optimized the WinBio service — reduced delays when resuming from Modern Standby. Reduced frequency of unexpected Windows Hello Enhanced Sign-in Security authentication lockouts — resolved an issue with missing secure registration metadata. Improved login behavior: if Windows Hello (facial recognition) or Windows Hello (fingerprint) is configured and available, it is now the default sign-in method each time, even if you previously used a different method. If you prefer using a PIN instead and enter it three times in a row, the system will stay on the PIN method until you manually switch to another method.
- Windows Search Box. Search now finds and prioritizes files after typing just two characters.
- Storage. When creating a Dev Drive, the dialog box now allows specifying the size in gigabytes, not just megabytes. The same applies to resizing volumes via Settings > System > Storage. Updated the Settings > System > Storage section — the UAC prompt now appears not when opening the page, but only when navigating to view temporary files.
- USB. Improved reliability of displays connected through USB4 docks and hubs — the image appears more consistently when resuming from sleep mode. The USB3 stack has received additional resilience and recovery mechanisms for specific hardware failures — USB devices operate more reliably.
- Sensors. Improved protection against applications that may keep the sensor hub active and drain the battery.
- HID Devices. Extended battery life in scenarios with malfunctioning HID devices — the operating system no longer keeps the HID/Input stack active for them. Enhanced power hygiene regarding applications that may initiate data exchange with HID devices in sleep mode.
- Input. Improved reliability of invoking the touch keyboard on the login screen when entering or changing a password. Enhanced stability of explorer.exe when closing the input switcher. Accelerated opening and navigation of clipboard history.
- Fonts. Rendering improvements have been made to the Times New Roman font family for combined diacritical marks in Greek and Cyrillic alphabets. Fixed character positioning issues — text is displayed more accurately and consistently.
- Task Scheduler. Now preserves column width settings in task list mode between sessions.
- Desktop Icons. Improved reliability of loading application shortcuts on the desktop.
- Microsoft Store. Made changes that improve download performance and optimize bandwidth usage. Enhanced error messaging when downloads fail due to the Windows Update group policy being enabled.
- Authentication. Improved secured Netlogon connections between domain controllers — connections from a domain member server to domain controllers configured through 2025 are now successfully established.
- BitLocker. Improved BitLocker testing reliability — necessary files are now available for the BitLocker Drive Encryption USB BIOS Logo Test.
Overall reliability of Windows has also been improved on login and lock screens, in File Explorer, when using gestures on touch devices, and when switching themes in Settings.
