Microsoft Releases Windows 10 Build 21337

Microsoft today is releasing Windows 10 build 21337 to Insiders in the Dev Channel. This version follows up build 21332. Unlike the last build this one contains some additional features that are being introduced. Here is a look at what to expect.

Windows 10 Build 21337

You can now customize and organize your virtual desktops. “Virtual Desktops help you cognitively separate different tasks on your PC, including helping to create work-life separation. They can be swapped into view, letting you shift your work from one desktop to another. Instead of juggling multiple windows, you can switch between Virtual Desktops to multitask,” notes Microsoft.

Changes are also with File Explorer. Which includes a new “compact mode” in the View tab.

There are also changes to caption settings, inbox apps, Notepad is being updated via Microsoft Store, Windows Terminal is now an inbox app, and Power Automate Desktop in now an inbox app.

For gamers, there is now a preview of Auto HDR for PC gaming. “ When enabled on your HDR capable gaming PC, you will automatically get awesome HDR visuals on an additional 1000+ DirectX 11 and DirectX 12 games! Check out our DirectX blog post for more details.”

Here is the list of changes and improvements in this build:

  • We are now rolling out the new IME candidate window design to all Windows Insiders I the Dev Channel using Japanese, Chinese Traditional, and Indic IMEs. We’ll let you know once the rollout for the remaining IMEs increases.
  • We’re updating the emoji panel (WIN + Period) to support searching 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). Please continue sharing feedback about the emoji search results in the Feedback Hub under Input and Language > Emoji Panel.
  • Live previews for websites pinned to the taskbar from Microsoft Edge are now rolling out for all Insiders.

And the following is the list of Fixes contained in today’s new release:

  • We fixed a DWM memory leak impacting Insiders in recent flights.
  • We fixed an issue resulting in errors for some Insiders when trying to launch Settings via URI, including when using the Display Settings and Personalization options when right clicking the desktop.

A Reminder about Insider Builds

Remember that Insider builds are meant for coders, IT admins, and Windows 10 enthusiasts who want to test new features and submit feedback to Microsoft.

These builds are not meant for inexperienced users. They are also not meant to run on your primary production machine. Insider builds contain many known stability issues that can cause your system to become unstable or even crash.
