    How to Enable or Disable Virtualized GPU (vGPU) Sharing for 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 the virtualized GPU.

    If you enable this policy setting, vGPU will be supported in the Windows Sandbox.

    If you disable or do not configure this policy setting, Windows Sandbox will use software rendering, which can be slower than virtualized GPU.

    This tutorial will show you how to enable or disable virtualized GPU (vGPU) sharing for Windows Sandbox for all users in Windows 10.

    You must be signed in as an administrator to enable or disable virtualized vGPU sharing for Windows Sandbox.

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


    Enabling virtualized GPU can potentially increase the attack surface of the sandbox.

    I have been dabbling for a couple of days with this feature finding it vanilla and not much showcases on it working .

    Basically if I understand correctly from my researches it is only aimed for laptops with Intel GPU & Nvidia / AMD higher performance GPU where when enabled the sandbox will persist to show the main card as VM Video card with low capabilities but will show the higher performance GPU in device manager as a secondary option just as it is with dual graphics laptops normally .

    The problem is all my researches show people complaining its not working , that I even have a post by a MVP replying to someone wondering why he cant get it to work that the sandbox environment is pretty basic and may not support video or gaming what so ever found on the Microsoft support forum .

    Then a guy on Youtube posted a video that it works smoother on Windows 11 than it would on Windows 10 and he did show it appearing in device manager , he made me revert to Windows 11 only to find it all the same , no presence of it what so ever despite even applying upper patches .

    Now I returned to that post on Youtube to find the entire comments wondering how he made it work as its not acting the same for which where the guy decided to reply maybe its a driver issue for them .

    Honestly I tried switching between last driver in all generations of Nvidia (3xx/4xx/5xx) to no use , so bottom line is this thing vanilla really or there are any mean to make it work ? If so , how ?




    PS: Please Provide driver version to install if it was really a driver issue , thanks in advance!
