Windows 10 build 21382.1

Windows 10 build 21382.1 is the eighteenth Insider Preview build of Cobalt, the 21H2 development semester of Windows as a service. This build was released on 14 May 2021 to all Windows Insiders on the Dev Channel.

Changes

 * The Start menu now launches shortly after an upgrade or clean installation is done to help users quickly get to their apps.
 * The new default folder icon in File Explorer introduced in build 21343 has been slightly changed to show if a folder has content or not.
 * The touch keyboard now uses the Segoe UI Variable font introduced in build 21376. Icons such as the microphone in the dictation key and those in the candidate bar have also been updated to match the design of those included since build 21327.

News and interests

 * The flyout might occasionally flash in the screen's top left corner when opened.

Camera Settings

 * The Camera app does not respect the brightness adjustments made to a camera under its respective page.

Installation

 * The update process to this build has a chance of hanging for extended periods of time.
 * The text might appear in the Times New Roman font in the upgrading and welcome animation screens.
 * Some devices might fail to upgrade to this build with error code.

General

 * Certain parts of Search, including the File Explorer search box, are not displaying correctly in the dark theme.
 * The icons for Microsoft Edge and File Explorer in the taskbar are swapped in clean installations.
 * Taskbar buttons may appear overlapped for a while.
 * Some devices might have the .NET Framework cumulative update reoffered in Windows Update Settings after it is installed. Pausing and resuming updates often workarounds this issue, but if it is still detected, it should download and install again successfully and no longer display afterwards.
