How to Enable Sandbox on Windows 10: Step-by-Step Guide to Activate and Use Windows Sandbox

Windows Sandbox is a lightweight desktop environment designed to safely run untrusted applications without affecting your main system. It creates a temporary, isolated space where you can test software or browse files securely. This feature is especially useful if you want to try out a program without risking malware or other issues.

Enabling Windows Sandbox on Windows 10 is straightforward but requires specific system configurations. Once activated, you can launch the sandbox environment quickly and safely test anything you want.

In this guide, we will walk you through the exact steps to enable and use Windows Sandbox, explaining each part clearly. Whether you are a beginner or just need a refresher, this step-by-step process will help you set it up without confusion.

Let’s get started with the basics and ensure your system is ready for Windows Sandbox.

Quick Note: Prerequisites and System Requirements

  • Windows 10 Pro, Enterprise, or Education: Sandbox is not available on Windows 10 Home edition.
  • Build Version: You need Windows 10 version 1903 or later for Sandbox support.
  • 64-bit Processor: Your CPU must support virtualization technology (Intel VT-x or AMD-V).
  • Virtualization Enabled: Virtualization must be enabled in BIOS or UEFI settings.
  • At least 4GB RAM: Recommended to run Sandbox smoothly.
  • Free Disk Space: Ensure you have some disk space as Sandbox uses system resources for temporary files.

Checking these before you begin will save time and prevent errors during setup.

Step 1: Enable Virtualization in BIOS/UEFI

Virtualization technology is essential for Windows Sandbox to work. This setting is usually disabled by default on many computers, so you need to turn it on manually.

  1. Restart your computer and enter the BIOS/UEFI setup. This is typically done by pressing Delete, F2, or F10 key repeatedly during boot (check your PC manual for exact key).
  2. Look for settings named “Intel Virtualization Technology,” “VT-x,” “AMD-V,” or “SVM Mode” under the “Advanced,” “CPU Configuration,” or “Security” tab.
  3. Enable the virtualization option.
  4. Save changes and exit BIOS/UEFI (usually by pressing F10 and confirming).
  5. Allow your computer to restart normally.

Why this matters: Without virtualization enabled, Windows Sandbox cannot create the isolated environment it needs.

Step 2: Turn On Windows Sandbox Feature

Once virtualization is enabled, the next step is to activate Windows Sandbox from Windows Features.

  1. Press Windows Key + S and type Turn Windows features on or off, then press Enter.
  2. In the Windows Features window, scroll down and find Windows Sandbox.
  3. Check the box next to Windows Sandbox.
  4. Click OK. Windows will apply the changes and may ask you to restart your PC.
  5. Restart your computer if prompted.

Why this matters: Enabling Windows Sandbox from features installs the necessary components to run the sandbox environment.

Step 3: Launch and Use Windows Sandbox

After restarting, you can open Windows Sandbox to start testing applications in a safe environment.

  1. Press the Windows Key and type Windows Sandbox.
  2. Click on the Windows Sandbox app to open it.
  3. A new window will open showing a clean, isolated desktop environment.
  4. You can now copy files or installers from your main system into the sandbox by simple drag-and-drop or copy-paste.
  5. Run the applications inside the sandbox environment.
  6. When you close the Sandbox window, everything inside is permanently deleted, ensuring no changes affect your main system.

Why this matters: Each time you open Windows Sandbox, it starts fresh with no previous data, providing a secure testing environment.

Alternative Method: Enable Sandbox Using PowerShell

If you prefer using command line, you can enable Windows Sandbox through PowerShell as an alternative to the Windows Features method.

  1. Press Windows Key + X and select Windows PowerShell (Admin) or Terminal (Admin).
  2. In the PowerShell window, type the following command and press Enter:
Enable-WindowsOptionalFeature -FeatureName "Containers-DisposableClientVM" -All -Online
  1. Wait for the process to complete and then restart your PC.

This method performs the same function as enabling the Sandbox through Windows Features but can be faster for users comfortable with command line tools.

FAQs About Windows Sandbox

Can I use Windows Sandbox on Windows 10 Home?

No, Windows Sandbox is only available on Windows 10 Pro, Enterprise, and Education editions. Home edition does not support this feature.

What happens to files saved inside the Sandbox?

All files and changes inside the Sandbox are deleted once you close it. It is a temporary environment designed to leave no trace on your main system.

Does Windows Sandbox require a lot of system resources?

Sandbox uses your CPU, RAM, and disk space temporarily while running. It is recommended to have at least 4GB of RAM and a capable processor for smooth operation.

Can I customize Windows Sandbox settings?

Yes, advanced users can create configuration files to customize networking, shared folders, and other Sandbox options. However, this is optional and not required for basic use.

Why can’t I find Windows Sandbox in Windows Features?

This usually means your Windows version or edition does not support Sandbox, or virtualization is not enabled in BIOS. Check prerequisites carefully.

When Nothing Works

If Windows Sandbox won’t enable or run properly after following these steps, try the following:

  • Double-check that virtualization is enabled in BIOS.
  • Make sure your Windows 10 is fully updated to the latest version.
  • Run sfc /scannow in Command Prompt to fix corrupted system files.
  • Consider updating your device drivers, especially CPU and chipset drivers.
  • Visit the official Microsoft support page for Windows Sandbox troubleshooting: Microsoft Docs – Windows Sandbox.

Conclusion

Enabling Windows Sandbox on Windows 10 is a powerful way to safely test applications without risking your main system. By ensuring your device meets the prerequisites, enabling virtualization, and turning on the Sandbox feature, you can create a secure, disposable environment with ease.

This guide has walked you through every step, from BIOS setup to launching the sandbox, including alternative methods and common troubleshooting tips. With Windows Sandbox, you have a simple yet effective tool to protect your PC while exploring new software or files.
