Microsoft today updated its development channel with a new version. The Windows 10 Insider Preview build 21343 includes some new icons in File Explorer. New colored icons are now displayed for user folders such as images, documents, etc. In addition to this change, improvements have been made to Windows Sandbox and Microsoft Defender Application Guard.
What’s new in Windows 10 Build 21343
New icons in the file explorer
The new icons are part of a broader redesign of icons in recent versions of Windows 10. Most of the built-in applications have already received their bright and colorful icons, and now it’s File Explorer’s turn.
Most of the symbols now look new. These include custom folders, drives and some keys. Some symbols have a different style that fits well with the dark theme. There is also a new shopping cart icon.
Microsoft said the number of icons would increase over time.
Improvements to Windows Sandbox and Microsoft Defender Application Guard (MDAG)
Both Windows Sandbox and Microsoft Defender Application Guard use the special container technology built into Windows 10. Previously, the operating hours of the container coincided with those of the host. Starting with version 21343, Microsoft delivers a new runtime engine designed and optimized for containerized scenarios. It is lightweight and provides faster startup times for Windows Sandbox and Microsoft Defender Application Guard.
In addition, the Windows sandbox now includes the new Microsoft Edge browser, which is based on Chromium (as of version 21313).
This change should not affect the compatibility of applications in the Windows Sandbox environment. However, this is a significant change and users may notice some differences in behavior.
The official announcement also includes the following list of changes and improvements.

- Games] There is an issue in this version where some games may crash, saved data may not be synchronized when played on another device, or may not be saved when a new game is installed. Microsoft is working on the patches, but if you think you are affected, you are advised to suspend the update until the company releases a new build with the patches, to avoid possible data corruption.
- After installing this version, all folders with access to DeepL in File Explorer will disappear. Please note what was attached before the update so you can find these files.

- The network drop-down menu on the login screen does not open on this version, so you cannot connect to the new network before logging in. If your account requires an Internet connection, you can work around the issue by establishing an Ethernet connection, bringing the device within range of your previously configured Wi-Fi network, or signing in first with another available account.
- The handwriting input field does not work for pen input on ARM64 computers in this version.
- There is an issue in this version that may cause the search to fail on startup for some insiders. The solution is on its way.
The Device Channel, formerly known as the Quick Ring, reflects recent changes in the Windows code base. Therefore, the changes you see in the dev channel versions may not appear in the next feature update. So we can expect some features that will never appear in stable versions of Windows 10 to make their appearance on the desktop.
If you have set your device to receive updates through the device/quick dial channel, open Settings – > Update & Recovery and right tap Check for updates. Allows you to install the latest available version of Windows 10 Insider Preview.
