What you need to know

  • Windows 10 build 21343 is now available for Insiders in the Dev channel.
  • The build includes new icons for the Windows 10 File Explorer.
  • The update also includes several other improvements and fixes.

Windows 10 build 21343 is rolling out to Insiders in the Dev channel. The build includes several improvements and changes. The one that will catch most people's eyes is that the Windows 10 File Explorer now has new icons, including a new recycle bin icon.

Microsoft describes some of the changes it made with the icons within File Explorer in a blog post:

Several changes, such as the orientation of the folder icons and the default file type icons, have been made for greater consistency across Microsoft products that show files. Notably, the top-level user folders such as Desktop, Documents, Downloads, and Pictures have a new design that should make it a little easier to tell them apart at a glance. And yes, the Recycle Bin icon has also been updated!

The build also improves Windows Sandbox and Microsoft Defender Application Guard. This update brings a new runtime designed and optimized for container scenarios.

Here are the other changes and improvements within Windows 10 build 21343:

  • We're changing the name of the Windows Administrative Tools folder in Start to Windows Tools. We are working to better organize all the admin and system tools in Windows 10.
  • [News and interests] Update on the rollout: following our last update on languages and markets, this week we're also introducing the experience to China! We continue to roll out news and interests to Windows Insiders, so it isn't available to everyone in the Dev Channel just yet.
  • We are now rolling out the new IME candidate window design to all Windows Insiders in the Dev Channel using Simplified Chinese IMEs.
  • We're updating the "Get Help" link in the touch keyboard to now say "Learn more".
  • We're updating File Explorer when renaming files to now support using CTRL + Left / Right arrow to move your cursor between words in the file name, as well as CTRL + Delete and CTRL + Backspace to delete words at a time, like other places in Windows.
  • We've made some updates to the network related surfaces in Windows so that the displayed symbols use the updated system icons we recently added in the Dev Channel.
  • Based on feedback, if the Shared Experiences page identifies an issue with your account connection, it will now send the notifications directly into the Action Center rather than repeated notification toasts that need to be dismissed.

You should be able to grab the update now if you're a Windows Insider in the Dev channel.
