How to use Windows Sandbox on Windows 11

On Windows 11, “Windows Sandbox” is a feature that creates a lightweight virtualization environment, which allows you to install and test untrusted applications or websites without the risk of affecting the main installation. 

In other words, Windows Sandbox is essentially a virtual machine that the Microsoft hypervisor creates on demand using the same image of the version of Windows 11 installed on your computer. The difference is that this is a custom lightweight (100MB~) virtualization environment optimized for performance and security.

Although you can use any other virtualization technology, Windows Sandbox offers some benefits. For example, you don’t need another product key to activate the instance, and you do not have to spend extra time setting up the virtual machine. Also, you will start with a clean Windows 11 installation whenever you open the sandbox, and everything will get deleted every time you close the feature.

This guide will walk you through the steps to set up and use Windows Sandbox on Windows 11.

On Windows 11, enabling the isolated environment to test applications requires turning on virtualization at the hardware level before you can turn on Windows Sandbox. 

As part of the minimum requirements, you will need Windows 11 Pro or higher, a processor with two or more cores, and at least 4GB of memory, and while it’s not a requirement, you will also need SSD storage.
