Windows Sandbox is one of the best security features for
anyone who has ever downloaded a suspicious file but didn’t
want to run it on their system or set up a virtual test
Windows Sandbox was added to Windows 10 with May 2019 Update
and it basically allows users to create a temporary desktop
environment to run untrusted software and browse suspicious
websites. The entire session is isolated, which means the
container won’t affect your computer.
This feature is offered with Windows 10 Pro and Enterprise
editions only, and it’s based on Windows Container technology.
To support sandbox isolation, Microsoft modified Windows
Containers, added support for runtime and integrated features
like “integrated scheduler” within the operating system.
All these features for the sandbox made it more suitable for
running on laptops, 2-in-1s and as well as desktops.
The problem with the current configuration is that the
container’s runtime matches the host, which could degrade the
performance and users might notice slower launch time.
Thankfully, with Windows 10’s Sun Valley update, which is due
to arrive later this year, Microsoft is introducing a new
runtime that will ensure ‘better’ performance for Windows
Sandbox and other container programs/features like Microsoft
Defender Application Guard (MDAG).
In the next update, Windows Sandbox technology will be based on
a new runtime specially optimized for container scenarios. The
upgraded Windows Sandbox would be more lightweight and it will
also launch faster, especially on computers with older hardware
or slower processor.
Microsoft’s new runtime will also improve the performance of
the Microsoft Defender Application Guard, an enterprise-only
feature designed to prevent attacks and protects employees in

In addition to Windows Sandbox 2.0,
Microsoft is also testing new Fluent icons for File
Explorer and adding support for additional keyboard
shortcuts – CTRL + Left / Right – when renaming your files.
Starting with Windows 10 version 21H2, you can finally use CTRL
+ Left / Right arrow to move your cursor when renaming files
and CTRL + Delete and CTRL + Backspace to delete words at
Microsoft is planning to launch these new features for
consumers in October or November of this year.
