What Is Windows Sandbox?

Windows Sandbox is a built-in lightweight virtual machine that enables you to run applications and programs in an isolated environment. It acts as a temporary desktop environment, allowing you to test potentially harmful or untrusted software without putting your actual operating system at risk. Once you close the sandbox, all changes and modifications made within it are discarded, ensuring a clean and secure experience every time.

Windows Sandbox was first introduced with the release of Windows 10 May 2019 Update (version 1903) and has since become a valuable tool for users seeking a safe and convenient way to experiment with software without jeopardizing the stability of their primary operating system.

Each time Windows Sandbox is launched, it starts with a fresh and clean installation of Windows, ensuring a pristine environment for testing and experimentation.  Any changes made or files created within Windows Sandbox are not persistent and are automatically discarded when the sandbox is closed. 

Benefits of Using Windows Sandbox

Using Windows Sandbox offers several advantages for both regular users and IT professionals. Let’s take a closer look at the benefits it brings to the table:

• Enhanced Security: Windows Sandbox provides a secure testing environment, preventing any potential threats from infiltrating your main operating system. It acts as a protective shield against malware, viruses, and other malicious software.
• Isolation: By running applications within Windows Sandbox, you can ensure that any changes made or files created during testing are contained within the sandbox. This isolation prevents any interference with your primary system and guarantees a clean slate with each sandbox session.
• Convenience: Windows Sandbox is easy to use and requires no additional setup. It comes pre-installed with Windows 10 Pro and Enterprise editions, making it readily available for business and professional users. Simply launch the sandbox and start testing right away!
• Time and Cost Efficiency: Windows Sandbox saves time and resources by eliminating the need for dedicated virtual machines or separate physical machines for testing purposes. It offers a lightweight solution that can be quickly set up and discarded after use.

If you often download and test unknown applications, Windows Sandbox offers an effective way to maintain the security of your system while still being able to explore new software.

How Does Windows Sandbox Work?

Windows Sandbox leverages the virtualization technology built into Windows 10 to create an isolated environment that closely emulates your actual system. When you launch Windows Sandbox, a pristine copy of Windows 10 is created, which is entirely separate from your host operating system. This ensures that any changes or malware within the sandbox cannot affect your primary system.

The sandbox environment is designed to be disposable and lightweight, allowing it to be quickly created and torn down as needed. It shares the same kernel with the host operating system, eliminating the need for additional resources while still providing a secure separation.

Windows Sandbox System Requirements

Before enabling Windows Sandbox, it’s important to ensure that your PC supports the virtualization technology required by Sandbox. Here’s a step-by-step guide on how to check if your PC supports virtualization:

1. In Windows 10, right-click the Taskbar and select Task Manager. In Windows 11, you can either press Ctrl + Shift + Esc or click the Search icon, start typing “Task Manager,” and then select “Task Manager” from the results.
2. If the Task Manager window appears compact, click on “More details” at the bottom to expand it and reveal all the tabs.
3. Select the “Performance” tab to view the performance details of your PC.
   
4. Look for the entry labeled “Virtualization” under the “Performance” tab. Make sure it says that virtualization is enabled.
   

If “Virtualization” is enabled, your PC supports the necessary virtualization technology for Windows Sandbox. If it’s disabled, you may need to enable virtualization in your PC’s BIOS settings. The process for enabling virtualization in the BIOS varies depending on your computer’s manufacturer, so refer to your device’s documentation or manufacturer’s website for specific instructions.

How to Enable Windows Sandbox
