What’s new on Windows 10 build 21382

Here are the new features, changes, and improvements with the latest preview of Windows 10.

Color-managed apps with HDR support

Starting with build 21382, Windows 10 adds a feature that allows creative and artistic apps that use the International Color Consortium (ICC) color profiles to render accurate color and access the full gamut of an HDR capable display.

If you have an app (such as Adobe Photoshop, Adobe Lightroom Classic, and CorelDraw), close it, right-click the app, and select the Properties option. Then in the “Compatibility” tab, under the “Settings” section, check the Use legacy display ICC color management option.

Once the HDR feature is enabled, only when in HDR mode, the option will take effect.

Device Manager new sorting option

This flight also updates Device Manager with new options to view the list of hardware by drivers, type, and devices from the “View” menu.

Start menu behavior

The Start menu does not include any new visual changes but starting with build 21382, after a fresh installation or upgrade, the menu will launch automatically upon setup completion. This should allow users to get a visual queue where to start and launch apps quickly.

File Explorer

As part of the File Explorer improvements, this update introduces a new folder icon that will indicate that the folder has contents.

  • The Camera app does not respect the default brightness setting set available on the new Camera Settings page.
  • Windows Search elements no longer display correctly in the dark theme.
  • The “news and interests” taskbar widget has an issue that may occasionally flash in the top left corner of your screen after clicking the button on your taskbar.
  • During the upgrade and in the initial welcome screens when after first signing in after upgrading, you may unexpectedly see the text that appears to be displayed in “Times New Roman” font.
