Windows 10 21343 is available for the Insider to download - New icons in File Explorer

After some new functions were integrated in the last Windows 10 Insider, a new Windows 10 Insider Build 21343.1000 is available today, more precisely the 10.0.21343.1000 rs_prerelease created on March 20th. ready for download. Download Windows 10 21343 ISO (German, English) Download here.

Slowly but surely, according to the schedule, we are getting into the area where the internal teams have to decide whether their new functions can be marked as “final”. Then these new functions will continue to be used in the next builds and will later be integrated into Windows 10 21H2. These can also be functions that were not previously built into the Insider versions.

As always, we will try to provide the ISO files for this version as well and will then insert the link here. [Update]: The first is already entered in the link. But as always, let's get to the changes in this build.

The file explorer gets new icons. The icon of the recycle bin has also been changed. Everything related to the changes that have been going on for quite some time. The Windows Sandbox and Microsoft Defender Application Guard (MDAG) have also received a change. You are now using a new runtime “which is designed and optimized for container scenarios. It's lightweight and enables faster startup times for both Windows Sandbox and Microsoft Defender Application Guard. "

The sandbox now also has the new Microsoft Edge (Chromium) on board.

The main changes

• We change the name of the Windows Administrative Tools folder in the Start menu to Windows Tools. We're working to better organize all of the administrative and system tools in Windows 10.
• [News and interests] Update on the rollout: After our last update on languages ​​and markets, we are also introducing the experience in China this week! We're still rolling out news and interests to Windows Insider, so it's not yet available to everyone on the Dev Channel.
• We are now rolling out the new IME candidate window design to all Windows Insiders in the Dev Channel who use IMEs in Simplified Chinese.
• We are updating the "Get Help" link in the touch keyboard so that it is now "Find out more".
• We're updating File Explorer when renaming files to now support using Ctrl + Left / Right Arrows to move the cursor between words in the filename, and Ctrl + Delete and Ctrl + Backspace to delete words at once, as elsewhere in Windows.
• We've made some updates to the network-related interfaces in Windows so that the icons that appear use the updated system icons we recently added on the Dev Channel.
• Based on feedback, when the Shared Experiences page identifies a problem with your account details, it now sends the notifications straight to the Action Center instead of repeated notification toasts that need to be discarded.

Known issues in Windows 10 21343

• There is an issue in this build where certain games may crash, save data will not sync when playing a game on another device, or not save when installing a new game. We are working on a solution, but if you think you are experiencing this issue we recommend pausing the updates until we release a new build with the solution to avoid possible data corruption.
• [File Explorer] After installing this build, all folders pinned to Quick Access in File Explorer will disappear. Before updating, please make a note of what is pinned so that you can find these folders again.
• [File Explorer] For some insiders it can happen that the entire folder area is missing in the quick access. When this occurs, you can go through deleting the string

% appdata% \ Microsoft \ Windows \ Recent \ AutomaticDestinations \ f01b4d95cf55d32a.automaticDestinations-ms

restore the section, but not the items that are no longer pinned. We are working on a solution to this problem and thank you for your patience.

• We're investigating reports of the update process getting stuck for a long time when trying to install a new build.
• We are working on enabling the new system tray for existing pinned web pages. In the meantime, you can detach the webpage from the system tray, remove it from the edge: // apps page, and pin the webpage again.
• [News and Interests] If you press the ESC key to close an open context menu in the flyout, the entire flyout will be closed instead.
• [Messages and Interests] Sometimes you cannot use the stylus to exit the Messages and Interests flyout.
• [ARM64] Insiders who have installed the preview version of the Qualcomm Adreno graphics driver on the Surface Pro X may experience a reduced display brightness. This problem will be resolved with an updated version of the preview graphics driver at https://aka.ms/x64previewdriverprox. If you have this problem, please refer to the feedback collection for more information.
• The network flyout on the login screen does not open on this build, which prevents you from connecting to a new network before logging in. If your account is in a state that requires internet login, the workaround is to establish an Ethernet connection, bring the device within range of a previously configured Wi-Fi network, or use another available account first Sign in.
• The handwriting input field does not work for pen input on ARM64 PCs with this build.
• There is an issue with this build that may cause Search to crash on startup for some Insiders. We're working on a fix.
