New features and changes

Live captions

The live captions feature, initially introduced in build 22557, has been updated to support Chinese (Simplified and Traditional), French, German, Italian, Japanese, Portuguese (Brazil), Spanish and other English dialects.

File Explorer

• A partially functional File Explorer based on Windows App SDK has been implemented. This change is hidden by default, but can be toggled on manually by the following steps:
  • Enable the 40729001 (WASDKInFileExplorer), 40731912 (WASDKInXamlExtensionsUdk), 41969252 (MRTCoreSystemShimForWASDK), and 42922424 (TypeActivationRedirection) velocity IDs.
  • Take the ownership and then merge the following registry entry:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell\Update\Packages\MicrosoftWindows.Client.40729001_cw5n1h2txyewy]
"Compatible"=dword:00000001

• The Gallery page, initially implemented in build 25272, has been updated with a timeline scrollbar and the ability to add external library locations. These changes are disabled by default, but can be toggled on manually by enabling the Windows App SDK-based File Explorer and then enabling the 41040327 (FileExplorerGallery) and 42295138 (XAMLFolderViewSupport) velocity IDs.

Shell

• The following changes to snap layouts have been implmented and rolled out to a subset of users:
  • The hover time required to invoke the flyout when moving the mouse over the maximum/restore button in an app's title bar has been decreased. This change can be toggled on manually by enabling the 40851068 velocity ID with the variant parameter set to 1 or 2.
  • The target app's icon and a descriptive title "Snap this window" have been added. These changes can be toggled on manually by enabling the 40851068 velocity ID with the variant parameter set to 0 or 2.
• The ability to display seconds in the system clock on the taskbar, previously disabled in build 25295, has been re-enabled.
• The new "End task" option has been added to the app's context menu on the taskbar. This feature is disabled by default, but can be toggled on manually by enabling the 42592269 velocity ID.

Settings

• The button control for startup app items under App > Startup, initially implemented in build 25247, has been rolled out to all users.
• Right-clicking on a Win32 app in the Start menu and choosing "Uninstall" will be redirected to the Apps > Installed apps page.

Task Manager

• Pressing ↓ while doing a search will move the keyboard focus from the search box into the results.
• When the contrast theme is enabled and one of the rows in the Processes page is selected, that row will show that it's selected.

Miscellaneous

• The parital support of Emoji 15 has been implemented into the emoji picker, though the Segoe UI Emoji font has not been updated yet. This support is disabled by default, but can be toggled on manually by enabling the 40213648 velocity ID.
• When upgrading to the new Windows Subsystem for Linux Store app, the system will prompt for installation if wsl.exe is invoked.
• The Print Management snap-in is pre-installed.

Bugfixes

General

• Fixed the underlying issue related to combase.dll that was causing some apps that use GetKnownFolder APIs (such as Notepad and Terminal) to crash when IME is enabled.

• Fixed an issue that was causing authentication issues for enterprise websites that require windows integrated authentication.

Shell

• Fixed an issue where drag and dropping files and folders across File Explorer tabs wouldn't work properly.
• Fixed an issue where Narrator's focus wasn't going back to the Quick Settings' window correctly when using the back button in the Cast page.

Widgets

Fixed an issue that was causing third-party widgets to get unpinned when signed in with a Microsoft account across multiple devices. As a result, some third-party widgets may be unpinned when upgrading to this build.

Input

Fixed an issue where the IME candidate window and IME toolbar weren't shown or cropped sometimes.

Task Manager

• Fixed an issue where the dropdowns in settings might not match your currently selected theme.
• Fixed an issue that was causing search results to suddenly disappear when using search on the App History page.

• Fixed an issue where ragging the window using the search box area wouldn't work.
• Fixed an issue where ending processes in the Details tab wasn't showing a confirmation dialog.
• Fixed an issue where increasing the text scaling would result in a "see more" button appearing with no contents.
• Fixed an issue where focus might not get set properly to search, leading to Narrator not saying that focus was on the search box.
