How to Enable or Disable Video Input in Windows Sandbox in Windows 10


Windows Sandbox provides a lightweight desktop environment to safely run applications in isolation. Software installed inside the Windows Sandbox environment remains "sandboxed" and runs separately from the host machine.

A sandbox is temporary. When it's closed, all the software and files and the state are deleted. You get a brand-new instance of the sandbox every time you open the application.

Starting with Windows 10 build 20161, a new group policy setting was added that enables or disables video input to the Sandbox.

If you enable this policy setting, video input is enabled in Windows Sandbox.

If you disable or do not configure this policy setting, video input is disabled in Windows Sandbox. Applications using video input may not function properly in Windows Sandbox.

This tutorial will show you how to enable or disable video input in Windows Sandbox for all users in Windows 10.

You must be signed in as an administrator to enable or disable video input in Windows Sandbox.

Windows Sandbox is only available for the Windows 10 Pro and Windows Enterprise editions build 18305 and higher.


There may be security implications of exposing host (Windows 10 PC) video input to the container (sandbox).
