Changes and Improvements

[General]

  • The spelling dictionary will now use a language-neutral word list and we are trying out syncing this across all devices that use the same Windows account. Users can toggle this feature via Settings > Accounts > Windows backup > Remember my preferences > Language preferences. This currently only works with Microsoft accounts today with AAD support coming later.

[File Explorer]

  • File Explorer tabs and navigation updates (which began rolling out to the Dev Channel with Build 25136) are now rolling out to everyone in the Dev Channel. If you don’t see these features right away, please try rebooting. If that doesn’t work, please file feedback in Feedback Hub.

  • We’re trying out different experiences in File Explorer to show search results.

[Input]

  • We’re adding the Tamil Anjal keyboard for the Tamil language. It’s a popular keyboard for inputting Tamil characters, so if you speak this language, please try it out! This keyboard is currently rolling out to a subset of Insiders while we evaluate the quality. To add it (once it’s available to you), make sure Tamil (India) is listed under Settings > Time & Language > Language & Region, and then click the “…” next to the language, select Language Options, and add it to the list of keyboards.

  • We are rolling out a small tweak to improve the key repeat rate for the traditional touch keyboard layout, as well as the default touch keyboard layout, so it feels more responsive. Now it has the rate of 20 keys per second (for example, when holding down the delete key).

[Other]

  • Updated the default duration captured by powercfg -sleepstudy from 3 to 7 days.

ビルドには以下の既知の不具合が存在します。

[General]

  • [NEW] Devices with low disk space may be unable to update to this build and see download error 0x80070001 in Windows Update. A fix should go out with the next flight. Freeing up disk space 24GB or higher could allow the build to download and install.

  • Some games that use Easy Anti-Cheat may crash or cause your PC to bugcheck.

  • We’re looking into reports that audio stopped working for some Insiders after upgrading to the last flight.

  • We’re working on a fix for an issue leading to some Insiders experiencing a decrease in FPS when playing certain games in recent flights due to the wrong graphics card being used.

  • We’re investigating reports of a few different apps having started crashing in recent builds.

[File Explorer]

  • The left-half of the File Explorer title bar may not be draggable via mouse or touch.

  • The up arrow is misaligned in File Explorer tabs. This will be fixed in a future update.

  • We’re working on the fix for an issue causing Home, Documents, Pictures and potentially other folders to become unexpectedly duplicated in File Explorer’s navigation pane or appear on the desktop.

  • We’re working on the fix for an issue where the search box background in File Explorer might be the opposite color of your current mode.

  • We’re working on the fix for an issue causing the delete key to unexpectedly not work on files in File Explorer. If you encounter this, you should still be able to use the context menu to delete.

  • [NEW] We’re working on the fix for an issue where the taskbar isn’t able to display if File Explorer is maximized and you have the taskbar set to auto-hide.

[Widgets]

  • Notification badge number may appear misaligned on the taskbar.

  • In some cases, the notification banner for some badging will not appear in the widgets board.

[Printing]

  • We’re working on the fix for an issue in recent Dev Channel flights causing lines to not be included when printing tables from certain apps.
