== New features & changes ==
=== Settings ===
* The Color Management applet from Control Panel has been ported over to a new Color management page under System > Display.
* Support for controlling audio presets, ambient sounds, and experience enhancements for hearing aids has been implemented under System > Sound > Properties.
* Support for managing hearing aids has been implemented under Bluetooth & devices > Devices.
* Support for viewing essential Bluetooth device details (such as battery life and connection status) has been implemented under Bluetooth & devices > Devices.
* Starting from this build, Bluetooth devices discovery will always scan for all devices, but only show common device types by default. Whenever an uncommon device is found during the discovery process, an option to "Show more devices" will be displayed. As part of this change, the "Bluetooth devices discovery" toggle switch under Bluetooth & devices > Devices has been removed.
* A new "Windows protected print mode" section has been added under Bluetooth & devices > Printers & scanners.
* The "View Wi-Fi security key" option under Network & Internet > Wi-Fi > Manage known networks has been moved to the top of the Wi-Fi properties page under Network & Internet > Wi-Fi.
* Several changes to the System > Storage > Storage Spaces > Storage pool page have been implemented, including: remove confusing and/misleading status icons, replace links to Disk Management with links to Disks & Volumes, share drive labels and letter when applicable, offering an explanation for a term when hovering over it, and options to delete and upgrade a storage pool.
* A non-functional Display Connection section has been added under Display > Graphics, although clicking on it may crash the Settings app.
* A non-functional Speak for me page has been added under Accessibility. This page is disabled by default, but can be enabled by toggling on the 47123936 velocity staging key.
* A new "Automatic super resolution" toggle switch has been added under Display > Graphics for managing AI-powered screen upscaling feature. This feature is disabled by default, but can be enabled by toggling on the 39695921 velocity staging key with variant parameter set to 3.
=== Sudo ===
This build introduces Sudo for Windows, a tool inspired by the Unix sudo command which allows users to run other programs as the root superuser.Adoumie, Jordi. Introducing Sudo for Windows!, Windows Command Line. 8 February 2024. Retrieved 9 February 2024. Despite the name, Sudo for Windows is not based on its Unix counterpart, and is instead written from scratch in the Rust programming language. It does not aim to be compatible with the original implementation either due to the differences between the Windows and Unix permission systems, notably the absence of a superuser account. It can be enabled via the sudo config --enable command, or in the Settings app under System > For developers.
Sudo for Windows supports multiple modes of operation with varying levels of isolation from unelevated processes. The new window mode merely triggers a User Account Control prompt for the given command and exits. The input disabled and inline modes work by running a second, elevated instance of Sudo itself which runs the given command and redirects its standard streams (excluding the standard input stream if running in input disabled mode) via remote procedure calls to the original, unelevated instance.
Microsoft also announced that Sudo for Windows would eventually be released as open source: as of June 2024, the microsoft/sudo GitHub repository contains full source code, including documentation and minor C/C++ files which are likely stubs for specific operations.

=== Shell ===
* The context menu when hovering on the Copilot icon on the taskbar, initially implemented in build 23612, has been slightly refined as "Copilot actions" and publicly rolled out. The context menu will only show when performing certain actions (such as copying text), and the Copilot icon will correspondingly change its appearance and animate.
* The taskbar thumbnail previews have been redesigned with new hover and switch animations. This change is disabled by default, but can be activated manually by enabling the 29532725 velocity staging key.
* The drag and drop support for image files has been implemented into the Copilot icon on the taskbar.
* The energy saver icon in the system tray and Quick Settings has been updated to show two distinct icons in desktop devices and laptops.
* The "- File Explorer" suffix has been added to the preview thumbnail title in the taskbar, and Task View for File Explorer windows, and it will now indicate if File Explorer windows include multiple tabs.
* When clicking the "Show all devices" button under the "Add a device" window or the Quick Settings' Bluetooth flyout, the UI will seamlessly show all discovered devices.
* The text in the notification when a device detects a slow charger has been adjusted.
* A fade out transition effect has been added between OOBE and the first sign-in animation screen.
=== APIs ===
* Power Grid Forecast API has been implemented. It is designed to minimize environmental impact by shifting background tasks to times when more renewable energy is available in the local electrical grid.
* Support of key protection with virtualization-based security (VBS) has been implemented into Cryptography API: Next Generation (CNG) framework.Zhang, Emily. Advancing key protection in Windows using VBS, Windows IT Pro blog. 8 February 2024. Retrieved 9 February 2024.
* A new EFFECTIVE_POWER_MODE enumeration has been implemented into Effective Power Mode API for indicating the effective power mode the system is running.
=== Miscellaneous ===
* The reported version string has been changed from "23H2" to "24H2".
* The launch performance of File Explorer has been improved.
* The ReFS file system has been updated to version 3.14.
* Support of limiting a search to the currently selected key and its descendants has been implemented into Registry Editor.
* A new power setting GUID GUID_ENERGY_SAVER_STATUS (550E8400-E29B-41D4-A716-446655440000) has been implemented to represent energy saver status notification. Applications that register for this notification can save varying degrees of power depending on what energy saver mode is in effect.
* Windows Mixed Reality is deprecated and plugging in to use a Windows Mixed Reality headset will not work starting from this build. This includes the Mixed Reality Portal app, and Windows Mixed Reality for SteamVR and Steam VR Beta.
* Microsoft Defender Application Guard (MDAG) for Office and Edge is deprecated, and is no longer available as a feature on demand starting from this build.
* The ability to scan a QR code with Wi-Fi details in the Camera app to quickly connect to a Wi-Fi network has been implemented.
* The "Insider Preview" reference in the system has been removed, except for the watermark.
