How to configure and use Windows Sandbox?

What is Windows Sandbox?

As Microsoft said it is a lightweight desktop and isolation environment. It’s running independently from your main Windows, temporary and fresh Windows on each time you launch it. It’s useful for testing new applications, the untrusted software in an isolation environment that not get infecting your main Windows.

Let’s imagine you download software from an untrusted source, you would like to check it out but shy to install on your main computer since it may cause your computer virus-infected, you didn’t want to install a clean Windows or even set up a Virtual Machine since it takes too much time to install/setup.

Windows Sandbox will help you deal with your concerns. All the untrusted apps, the software will be in the Sandbox and it cannot affect your main Windows. After closing Sandbox, all the apps, software installed will be deleted permanently. Your main Windows will be safe.
