Microsoft has just released Windows 10 build 21343 for insiders in the Dev channel, and everybody can download it right now from Windows Update.
There are two notable alterations in this update: the addition of Fluent icons in File Explorer and enhancements for Windows Sandbox and Microsoft Defender Application Guard.
The File Explorer part is something that makes total sense, especially since Microsoft has been working on a new set of icons for Windows 10. The new icons thus supply the file manager having a more modern look, so it’s without a doubt a welcome refresh.
So far as Windows Sandbox and MDAG are concerned, both are supposed to get faster loading times, Microsoft explains.
“Both Windows Sandbox and Microsoft Defender Application Guard make the most of special container technology built into Windows 10. Previously, the container runtime matched the host. Starting with Build 21343, we’re introducing a brand new runtime that’s designed and optimized for container scenarios. It’s lightweight and allows faster launch times for both Windows Sandbox and Microsoft Defender Application Guard,” the organization explains.
“We do not expect this transformation to affect the application compatibility inside Windows Sandbox. However, this is a significant change and users may encounter some differences in behavior.”
Windows Sandbox now featuring Chromium Edge
Windows Sandbox has also been updated in the future using the new Chromium-based Microsoft Edge, thus replacing the legacy form of the browser.
More smaller changes are also part of this new release, including within the Start menu. Microsoft has renamed the Windows Administrative Tools within the Start menu to Windows Tools, because the company says it’s focusing on organizing the admin and system tools in a more straightforward manner.
