What’s new in Windows 10 Insider Preview Build 21337
Customize virtual desktops
Windows 10 comes with a built-in feature of virtual desktops. It is a neat feature to separate your tasks and not create clutter by opening many windows on the same desktop. Virtual desktop allows you to open and create different tasks on different desktops, while allowing you to move windows in between.
With build 21337, you can now rearrange your virtual desktops from the bar above by pressing the Windows key + Tab shortcut keys. This can be done either by the drag-and-drop method or by right-clicking a virtual desktop and selecting the move option from the context menu. Furthermore, you can also change the order for the virtual desktops by selecting the one you want to move with the arrow keys on the keyboard, then keep holding down the Alt + Shift key and use the arrow keys to move it.
Moreover, you can now also change the desktop background for each individual virtual desktop. This way, it will be easier for you to navigate between multiple desktops by recognizing the customized background while switching between the desktops, as well as in the thumbnails for the virtual desktops.
To check out this new feature, open the Background page in the Settings app and click the background you want to apply to your current, active desktop. To change the background of another virtual desktop, right-click the background and select the option to change the background for a specific virtual desktop from the context menu.
Layout changes for File Explorer
File Explorer is perhaps the most-used tool in a Windows environment. Microsoft has changed the default layout for Explorer by adding additional padding between elements to make it more convenient for the touch-screen users as well as in tone with a more modern look.
Having said that, Microsoft highlights the fact that the UX design is still not final. Hence, expect some further changes to the layout in the upcoming releases.
However, if you do not like the new layout, you can still revert back to the previous layout by clicking the Use compact mode in the View Options menu.
Auto HDR for PC
High Dynamic Range (HDR) is a technique where an image or a video is rendered to reproduce the light and the dark portions to present a more refined and detailed display. Auto HDR is now enabled with this build for computers and users will now get to enjoy this feature on thousands plus DirectX 11 and 12 games.
To learn how to enable this feature and use it to its maximum capacity, refer to this Microsoft blog post.
Microsoft has also made a few changes to the Captions settings in the Settings app. To see these changes, open the Caption settings.
However, Microsoft warns that discarding any changes made to these settings may not work in this build. Hence, we suggest that you make the changes wisely until Microsoft works on a fix for this issue.
Updates to various inbox apps
Notepad: The Notepad now has a new icon. Not only that, the application is now updatable through Microsoft Store and now has its own place in the Start Menu.
Windows Terminal: The Windows Terminal is a powerful tool that serves multiple purposes in the Windows environment. The app is now included as an inbox app and will continue to receive updates through the Microsoft Store.
Power Automate Desktop: The Power Automate Desktop is now also made an inbox app. This app allows you to automate applications on your computer by mimicking actions. Note that the application is still not available for ARM devices.
Word/Notepad as text editor of choice
Microsoft has given users the option to make Microsoft Word or Notepad the text editor app of choice. However, if you are still using WordPad as a text editor of choice, it will still be available.

- You will no longer be able to access the network flyout from the login screen after installing this build. Microsoft suggests that if you absolutely need to connect to a new network from the login screen, you can use a wired network, or take your computer closer to another wireless network that has been preconfigured so it will connect automatically.
- Some users with devices with certain NVMe drives may experience disk resets or WHEA_UNCORRECTABLE_ERROR bugchecks. If you have been a victim, Microsoft suggests that you pause the updates while they work on a fix.
- Some users might experience the DPC_WATCHDOG_ERROR bugchecks.
