Windows 11 build 25211.1001

Windows 11 build 25211 is the twenty-sixth Insider Preview and the twentieth available client build of Copper, the 23H2 development semester of Windows as a service. It was released to Windows Insiders in the Dev Channel on 29 September 2022.

Widgets
Three options for controlling Widgets taskbar behaviors have been added to the Settings page. As part of this change, the widget picker has been separated from the Settings page. This feature is only available to a subset of users.

Taskbar

 * The "Show hidden icons" overflow has been updated with the following changes, which can be toggled on manually by enabling the  velocity ID:
 * The rounded corners and shadow effect have been applied to the tray icon hitboxes.
 * The overflow will show five tray icons in a row instead of three.
 * The drag-and-drop feature for reorganizing tray icons, which had been disabled since the introduction of the tablet-optimized taskbar, has been re-enabled.
 * The tooltips on tray icons have been redesigned.
 * New animations have been added.
 * A new Task Manager item has been added to the taskbar context menu.

Settings

 * The support for uninstalling apps with inter-dependencies, repairing and modifying Win32 apps under Apps > Installed apps, which initially introduced in build 25169, has been removed.
 * The examples used in the Short time selection under Time & language > Language & region > Regional format has been updated to show morning and afternoon times.
 * The Archive apps option under Apps > Advanced app settings has been replaced with a toggle switch under the main page, rather than showing it in a separate page. This change is disabled by default, but can be toggled on manually by enabling the  velocity ID.

Task Manager

 * The graphs in the Performance page has been tweaked to use a bit more transparency.
 * The reliability of Task Manager has been improved.

General

 * Fixed an issue which was causing the "Date, time and time zone settings are incorrect" error message to be displayed when upgrading to build 25206.

File Explorer

Tablet-optimized taskbar

 * The taskbar may sometimes flash when transitioning between desktop posture and tablet posture.
 * The taskbar may take longer than expected to transition to the touch-optimized version when switching between desktop posture and tablet posture.
 * Using the left or right edge gestures may cause the Widgets or Notification Center (respectively) to overlap with or look truncated by the taskbar.

 * The taskbar may sometimes collapse unexpectedly when there are no running windows on the desktop.
