Windows 11 build 25206

Windows 11 build 25206 is the twenty-fifth Insider Preview and the nineteenth 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 21 September 2022, along with its server counterpart.

File Explorer
The ability to show show recent file activity for cloud files in search results has been added.

Shell

 * The redesigned Open With dialog box, which re-introduced in build 25151, has been rolled out to all users.
 * The missing computer icon in the legacy Shutdown Windows dialog has been re-added.
 * The new Spotlight UI, which introduced in build 25197, has been removed.

Settings
The Dynamic Refresh Rate (DRR) experience, which is accessible under System > Display > Advanced display, has been expanded to supported external displays.

Boot environment

 * Support for a new Hyper-V hypervisor calling convention has been partially added, although it currently relies on a function pointer that is not initialized at any point.
 * Hyper-V VMBus code changed; some changes here are related to the partition isolation type which was added in build 25179.
 * BitLocker recovery mode code changed. When a BitLocker recovery key is escrowed to a Microsoft account, the email address of that Microsoft account is now stored in on-disk BitLocker metadata. The boot environment code requesting the recovery key now checks for this additional metadata, and shows the Microsoft account email address (using new resource message ID ) if present.
 * This is in direct response to the Secure Boot revocation list update of August 2022, which caused actual data loss on some systems due to the presence of automatic BitLocker and users being unable to find or access their recovery key.

Miscellaneous

 * Starting with this build, the SMB authentication rate limiter has been enabled by default, along with the implementation of default 2-second delay between each failed NTLM or PKU2U-based authentication.
 * A change to suppose the use of the clipboard history on password fields has been rolled out to a subset of users.

General

 * Fixed the issue causing the OneDrive setup to ask for permission to set up every time Windows reboots.
 * Fixed a high hitting  crash.
 * Fixed a high hitting Search crash.
 * Fixed the issue causing the Windows Sandbox window to resize incorrectly when snapping it to the side of the screen.
 * Fixed an issue which could lead to a memory leak in Windows Error Reporting after certain crashes.
 * Fixed the issue when pressing Alt and ↵ Enter to open the legacy Shutdown Windows dialog, the keyboard focus would point to the checkbox rather than the OK button.

Settings
Fixed a Settings crash which could happen when searching and selecting certain Narrator related settings.

General

 * The audio may stop working in certain cases.
 * Several apps may crash on launch in certain cases.
 * The "Date, time and time zone settings are incorrect" error message may be displayed when upgrading to this build.
 * Using the "Reset this PC" option to reset Windows may break UWP apps post-reset.

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 stay stuck in the expanded state instead of dismissing to collapsed state when using the bottom right edge gesture to see Quick Settings.
 * The taskbar may sometimes collapse unexpectedly when there are no running windows on the desktop.

File Explorer
The command bar items, such as copy, paste, and empty recycle bin, may unexpectedly not be enabled.

Settings
Users may be unable to uninstall certain apps under the Installed apps page.

Shell
On some locales, the default font used in several UI elements (such as the date and time on the taskbar) may change to regular Segoe UI instead of Segoe UI Variable.

Virtualization

 * Users may experience a  bugcheck when booting Windows in VMware on a Hyper-V enabled host with 2 or more cores allocated.
 * The system may fail to boot in VMware with attached network adapters.

Widgets

 * The Notification badge number may appear misaligned on the taskbar.
 * In right-to-left display languages, the content may animate out of view before the Widgets board resizes when clicking to expanded view of the Widgets board.

Safe mode

 * Quick Settings and date/time clock on the taskbar may be missing due to the  service not running.
 * Clicking Bluetooth & devices and Personalization pages may crash the Settings app due to an overrun of a stack-based buffer.
