Microsoft optimizes the Windows Sandbox & Defender Application Guard performance
Windows Sandbox and Microsoft Defender Application Guard (MDAG) are security access applications based on container technology launched by Microsoft.
Among them, the virtual sandbox is mainly used to virtualize the subsystem so that users can run software in the subsystem. The subsystem is isolated from the host, so there is no security problem.
The application access function is a security-enhancing technology provided to enterprises. For example, documents and browsers can be placed in containers to avoid virus infection.
Long after the launch of these features, Microsoft is finally ready to optimize them, and Microsoft is currently using new technologies to optimize containers to make these features start faster.
Microsoft said that starting from Windows 10 Insider Preview Build 21343, it has added a new Runtime to the above-mentioned container technology-based functions to improve the running performance of the container technology.
According to Microsoft’s test, adding this new Runtime can improve the startup speed of sandbox and application access functions, such as the speed when a protected document is opened, and so on.
The company does not expect this change to cause compatibility issues with applications running in the sandbox, but this is a major change that may have some unknown issues.
Therefore, if the user relies heavily on the above functions, you may not upgrade for the time being, because after the upgrade, the user may encounter some strange conditions during use that affect the use.
After Microsoft continues to optimize and improve compatibility through subsequent versions, then consider upgrading. Of course, this has not been updated for users of the stable version, so it will not have an impact. Additionally, Windows Sandbox now includes the new Chromium-based Microsoft Edge browser.
