How to enable Windows Sandbox Mode in Windows 10 (Pro and Enterprise editions)

Windows Sandbox

Windows Sandbox is a Windows 10 feature which allows users to run a virtual copy of Windows 10 within Windows 10. The Sandbox quickly loads a clean copy of Windows where users can test run programs. It is also a good place to run any shady or untrusted programs and avoid malware attacks on the main install of Windows. Windows Sandboxes are a single-use platform wherein all data is trashed when users exit the Sandbox.

The support for Windows Sandbox is baked into Windows 10. However, the feature is only limited to the Pro and Enterprise editions of Windows 10. If you are a user of Windows 10 Home or Windows 10 S, then Windows Sandbox will not work and you should not follow this guide. The feature comes disabled by default even on the Pro and Enterprise editions. So, here’s how you can enable it.

Note regarding compatibility with other virtual machine programs: While I was testing Windows Sandbox, I noticed that my virtual machines created using Oracle Virtual Box would no longer launch. The machines kept failing with the error “VT-x is not available (VERR_VMX_NO_VMX)”.

So, Windows Sandbox is not compatible with other Virtual Machine programs. And you will need to Turn off Windows Sandbox if you need to use VMWare, Virtual Box or any other VM tool.
