Decoding Windows Sandbox: A secure virtual environment available on Windows

Windows Sandbox is a built-in feature in Windows 11 and Windows 10 Pro/Enterprise versions that allows users to create a temporary and isolated desktop environment. It's an ideal solution for running untrusted applications or accessing potentially risky websites without affecting the main operating system.

Essentially, Sandbox is a lightweight virtual machine, only about 100MB, that uses Microsoft Hyper-V technology to create a separate kernel. Any changes, files, or applications installed in this environment will be permanently deleted after you close the Sandbox window, ensuring that each startup is a completely new and clean session.

To use this feature, your computer needs to have virtualization enabled in UEFI or BIOS.

• Temporary data:All files, applications, and configuration changes will be permanently deleted when you close the Sandbox.
• Copy data:You can easily copy and paste files between the server and the Sandbox environment.
• System requirements:This feature is only available on Windows 10/11 Pro, Enterprise, or Education editions and requires hardware virtualization to be enabled in the BIOS/UEFI.
• Efficiency:Sandbox only consumes system resources (CPU, RAM) while it's running. When closed, it doesn't affect the overall performance of the machine.
