Allow vGPU sharing for Windows Sandbox

ComputerNative Intune settingAllowVGPU

Supported on SUPPORTED_Windows_11_0_NOSERVER_ENTERPRISE_EDUCATION_PRO_SANDBOX (defined in the Windows templates)

23H2 · 1.0

What it does

This policy setting is to enable or disable the virtualized GPU. If you enable this policy setting, vGPU will be supported in the Windows Sandbox. If you disable this policy setting, Windows Sandbox will use software rendering, which can be slower than virtualized GPU. If you do not configure this policy setting, vGPU will be enabled. Note that enabling virtualized GPU can potentially increase the attack surface of the sandbox.

What it writes

Hive: HKEY_LOCAL_MACHINE
Registry key: SOFTWARE\Policies\Microsoft\Windows\Sandbox
Value name: AllowVGPU
When enabled: DWORD 1
When disabled: DWORD 0

These deployment candidates come from the ADMX template; they are separate from the native CSP mapping above.

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
