Windows 10

Microsoft has rolled out another iteration of Windows Insider Update with the launch of the Windows 10 Insider Preview Build 21343. The Windows 10 Insider Preview Build 21343 is made available in RS_PRERELEASE mode and will be available to Windows Insiders in the Dev Channel. The update has introduced new system icons in File Explorer. The system icons that are used throughout File Explorer are getting refreshed with new icons. Previously, Microsoft updated icons for Windows Security, Narrator icon, and that of Notepad.

After the installation of Windows 10 Insider Preview Build 21343, any custom folders pinned to Quick Access will disappear. Microsoft has advised users to capture notes of them before initiating the update or pause until Windows 10 product team releases a fix. The orientation of the folder icons and the default file type icons have been designed to provide consistency across Microsoft products that display files. Additionally, the top-level user folders such as Desktop, Documents, Downloads, and Pictures including Recycle Bin have a new design. Microsoft will continue to update Windows 10 with new icons.

The Windows 10 Insider Preview Build 21343 ships with significant improvements to Windows Sandbox and Microsoft Defender Application Guard (MDAG). These modules leverage advantage of special container technology integrated into Windows 10.

Microsoft has introduced a new runtime that is designed and optimized for container scenarios with Build 21343. The runtime is lightweight and enables faster launch times for both Windows Sandbox and Microsoft Defender Application Guard. The Windows Sandbox includes the new Chromium-based Microsoft Edge Browser Build 21313.

The Windows 10 Insider Preview Build 21343 has changed the name of the Windows Administrative Tools folder in Start menu to Windows Tools. Going forward, we can expect enhanced management of all the admin and system tools in Windows 10. The News and interests module has been pushed to China region. However, Microsoft has completely withdrawn the News and interests in the previous update and is currently not available for all users in the Dev Channel.

The Windows 10 Insider Preview Build 21343 update has rolled out new IME candidate window design to all Windows Insiders in the dev Channel with the help of Simplified Chinese IMEs. Microsoft has updated the “Get Help” link on the touch keyboard to say “Learn more”. The File Explorer has been updated with support for CTRL+left/Right arrow to move the cursor between words in the file name.

You can also use CTRL+Delete and CTRL+Backspace to delete words at a time. The build also made updates to the network-related surfaces in Windows to enable displayed symbols to make use of the updated system icons that are added to the Dev Channel. If the shared experiences page identifies an issue with your account connection, then that module will deliver the notifications directly into the Action Center instead of repeated notification toasts.
