On Windows 11, the "Windows Sandbox" feature allows you to create a lightweight virtualization environment to install and test untrusted applications or websites without altering or affecting the main setup. 

In more technical terms, Windows Sandbox is a virtual machine that the system creates on demand with the Microsoft Hyper-V hypervisor using the same image of the version of the operating system currently on the computer. The only difference is that this is a custom lightweight (100MB~) virtualization environment optimized for performance and security.

Although you can use any other virtualization technology, this feature offers extra benefits. For instance, you don't have 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 whenever you close it.

In this how-to guide, I will outline the steps to set up and use Windows Sandbox on your computer.

How to enable 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. 

If you want to use this feature, the device needs Windows 11 Pro or higher, a processor with two or more cores, at least 4GB of memory, and SSD storage (not a requirement, but it's recommended).

  1. Double-click the installer (.exe, .msi, or any other) to begin the installation.
  2. Continue with the on-screen directions to complete the installation.

Once you complete the steps, you can use the sandbox to test apps without compromising your setup. In addition to testing applications, you can use this environment to access untrusted websites without affecting your device configuration.

You can use the "Ctrl + Alt + Break" or "Pause" keyboard shortcut on Windows Sandbox to enter and exit the full-screen experience. If you use high contrast mode, you can use the "Shift + Alt + PrintScreen" shortcut to enable the feature in this environment.

After you're done testing, close Windows Sandbox by clicking the X (close) button, and the system will delete any content you may have created or configured and the virtual machine instance.
