Innovations

New icons in the ” Explorer»

Last year, Microsoft began updating icons in Windows 10, starting the process with pre-installed apps. Recently, the icons for “Windows Security”, “Screen Announcer” and “Notepad” have changed. Now the company is ready to take the next step by updating many of the system icons used in the “Explorer”.

Note that after upgrading to this build, all user folders pinned in the Quick Access section will disappear. You can either remember from before updating, and then re-pin from in the section, or pause receiving updates until the problem is fixed.

Windows Sandbox and Application Guard in Microsoft Defender take advantage of the special container technology integrated into Windows 10.

Previously, the container’s runtime environment corresponded to the host. Starting with build 21343, the company introduces a new runtime environment that is specifically designed and optimized for containers. It provides a faster startup of both Windows Sandbox and Application Guard in Microsoft Defender.
