The Microsoft Windows 10 Sandbox is a new security feature in Windows 10 Pro and Enterprise. The idea behind it is to try something out in a safe “sandbox”. For example, installing a potentially insecure application.

Let’s get started with the sandbox game….

How exactly does the Windows 10 Sandbox work?

The Windows 10 Sandbox is basically a slimmed-down and customised virtual Windows 10 machine. This is non-persistent, which means that all changes are gone after use. This means that all malware is deleted when the sandbox is closed and the next sandbox is clean again for playing.

What are the hardware requirements for Windows 10 Sandbox?

Since the Windows 10 Sandbox is based on virtualisation, the hardware must support virtualisation and hardware-based virtualisation for kernel isolation. Other requirements are at least 4GB of RAM according to Microsoft (My tip: not less than 16GB), and at least 1GB of free hard disk space. For the CPU, Microsoft recommends 4 cores with hyper-treading, but at least 2 cores.

Can you test the Windows 10 Sandbox in a VM?

Yes, this works if “Nested Virtualization is supported. Under Hyper-V, the is activated with the following command: Set-VMProcessor -VMName -ExposeVirtualizationExtensions $true

Are there any restrictions in the Windows Sandbox?

    After installation, Google Chrome can be used as usual. This way, you could also surf without worrying about tracking and browser history or drive-by virus attacks.
