How Do I Enable Windows Sandbox?

To enable Windows Sandbox, you need to turn on the "Windows Sandbox" feature through the "Turn Windows features on or off" panel, then restart your computer.

What is Windows Sandbox?

Windows Sandbox is a lightweight, isolated desktop environment that allows you to safely run applications or test files without affecting your host operating system. It's particularly useful for testing files or applications that might be dangerous or originate from unknown or untrusted sources, providing a secure space where any potential malware or system changes are confined and automatically deleted once the sandbox is closed.

Prerequisites for Windows Sandbox

Before you can enable Windows Sandbox, ensure your system meets the following requirements:

Operating System: Windows 10 Pro, Enterprise, or Education (build 18305 or later) or Windows 11. Home editions do not support Windows Sandbox.
Architecture: 64-bit processor.
Virtualization: Virtualization capabilities enabled in your computer's BIOS/UEFI. This is crucial for the sandbox to function.
RAM: At least 4 GB of RAM (8 GB is recommended for optimal performance).
Disk Space: At least 1 GB of free disk space (an SSD is recommended for better performance).
CPU: At least two CPU cores (four cores with hyperthreading is recommended).

Step-by-Step Guide to Enable Windows Sandbox

Follow these steps to enable Windows Sandbox on your system:

Check Virtualization Settings:
- Press Ctrl + Shift + Esc to open Task Manager.
- Go to the Performance tab and select CPU.
- Look for "Virtualization." If it says "Enabled," you're good to go. If it's "Disabled," you'll need to enable it in your computer's BIOS/UEFI settings. (Refer to your motherboard's manual or manufacturer's website for specific instructions on how to access and enable virtualization in BIOS/UEFI).
Open Windows Features:
- Type "Turn Windows features on or off" into the Windows search bar (or Start Menu) and select the corresponding result.
Enable Windows Sandbox:
