Windows 10 is getting a new preview Build 21337 for users
testing version 21H2 “Sun Valley” update in the Dev Channel of
the Insider program. Windows 10 21H2 Build 21337 contains
numerous tweaks for Virtual Desktops, Windows File Explorer,
and in-box apps (pre-installed apps).
Windows 10 21H2 preview comes with notable improvements for
Virtual Desktops, which is a feature that lets you create
separate desktops where each can display different open windows
Microsoft recently added the option to rename virtual desktops
and you can now reorder and customize the backgrounds of your
virtual desktops. If you want to change the order of the
virtual desktops, right-click on it and select “Move left”
or “Move right”. You can also use ALT + Shift + Left and Right,
but mouse support is currently not included.
With the update, Microsoft is now allowing users to change the
order of the virtual desktops inside the Task View, and you can
even have different wallpapers for all virtual desktops.
So instead of virtual desktops simply using assigned
names, you will be able to set a custom wallpaper for each
virtual desktop, which is definitely a useful touch if you’re
unable to find the correct desktop.
Microsoft is also introducing support for “Auto HDR”, which
will automatically improve your gaming experience on supported
monitors when you use supported DirectX 11 and DirectX 12
Windows 10 Sun Valley update will also introduce a new layout
for File Explorer with additional padding between elements,
such as columns and rows. If you prefer the old or “classic”
layout, Microsoft will allow you to switch back by enabling a
new option called “Use compact mode”.
For now, it looks like Microsoft is planning to enable
touch-friendly UI for File Explorer by default and users will
have to switch back manually.
In addition to design tweaks,
Microsoft is also working on performance improvements for File
Explorer and improved search filters support.
You can now go to Settings > Ease of Access >
Hearing > Captions and customize the captions in Windows 10
apps, such as Movies & TV and Microsoft Edge.
