Windows 10 build 21337, according to the company, updates the Virtual Desktops feature to include new customization options. File Explorer ships with layout tweaks, and the Captions settings are getting new changes.
Also, build 21337 introduces changes for some of the built-in apps, including a Notepad app that receives updates from the Microsoft Store. The Windows Terminal app and Power Automate will be added by default during installation and more.
Windows 10 build 21337 new features and changes
Here is the new improvements shipping in the latest flight of Windows 10.
Starting with build 21337, Virtual Desktops includes the ability to reorder by dragging-and-dropping the item and customize the desktop background by right-clicking the desktop and selecting the Change background option.
Although you are still not getting a modern version of the app, File Explorer now has additional padding between elements. Alongside this new change, if you prefer a more compact design, the View options include a new “Use compact” setting that you can use to enable or disable the new mode.
Auto HDR for Windows 10
Microsoft is also introducing Auto HDR (preview) for Windows 10 to improve the gaming experience. When you enable the feature, you will get HDR visuals on an additional 1000+ DirectX 11 and DirectX 12 games on supported devices. (You can learn more about the feature on this Microsoft page.)
In the Ease of Access section, the Captions settings page is getting updated with a new design that allows you to select the caption style more easily. The updated page also includes the option to create new, edit, and delete captions.
Windows 10 build 21337 is also making some changes to some of the built-in apps. For example, the Notepad app becomes an app that receives updates from the Microsoft Store.
The Windows Terminal app will be installed by default to run Command Prompt, PowerShell, and Windows Subsystem for Linux 2 command from a single modern interface.
Furthermore, Microsoft is also bundling the Power Automate Desktop app on Windows 10. The Power Automate Desktop app allows automating web and desktop applications by mimicking the user interface actions like clicks and keyboard input to automate repetitive tasks.
Along with the new features and visual changes, Windows 10 build 21337 is also integrating the new IME candidate windows design for Japanese, Chinese Traditional, and Indic IMEs.
The emoji panel (Windows key + period) is getting support in more languages, including Amharic, Belarus, Cherokee, Filipino, Faroese, Icelandic, Khmer, Mongolian (Cyrillic script), Burmese, Sindhi, Serbian (Cyrillic script), Serbian (Latin script), Swahili, Thai, Turkmen, Tonga, Uzbek (Latin script), and Cantonese (Traditional).
If you use Microsoft Edge, live previews for websites pinned to the taskbar are now available for all testers.
As part of the fixes, Microsoft is addressing memory leaks. Settings app crashes when opening the app with a URI and crashes with apps for ARM64. Also, this flight addresses unresponsive Windows Security app, freezing after locking and unlocking the device, flickering hovering over apps, UPS to show up in Device Manager with error code 43, and more.
Microsoft is listing the complete set of improvements, fixes, and known issues for Windows 10 Insider Preview build 21337 at the Windows Blog.
