For most people with the fear of running an unknown .exe on their PC, the common solution is to set up a virtual machine to check the apps. Microsoft has developed Windows Sandbox for anyone running Windows 10 to be able to launch apps in an isolated desktop environment. The feature, which will come to Windows 10 next year, creates a temporary desktop environment, a ‘sandbox’, to isolate a particular app.
Windows 10 testers will be able to start trying out this new feature once Microsoft ships build 18305 or later.
It is designed such that once you’ve finished running the app, the entire sandbox will be deleted. Although it will require virtualization capabilities enabled in the BIOS, you don’t need to set up a virtual machine.
Windows Sandbox, which Microsoft will be making available as part of Windows 10 Pro or Windows 10 Enterprise, is aimed at businesses primarily and also power users.
What the feature does is that it simply creates a new lightweight (100MB) installation of Windows, whenever Windows Sandbox is enabled — to run an app. Microsoft creates a separate kernel that’s isolated from the host PC.
