RemoteFX vGPU makes it possible for multiple virtual machines to share a physical GPU. This feature was first introduced in Windows 7 and was removed as an option for users in Windows Server 2019. The current implementation of RemoteFX vGPU appears susceptible to security vulnerabilities (see the FAQ section for CVE details). Because these newly identified vulnerabilities are architectural in nature, and the feature is already removed from newer versions of Windows, the July 14, 2020 security updates and all superseding Windows Updates will disable and remove the RemoteFX vGPU feature. Starting with the July 14, 2020 security updates, this and all superseding Windows Updates will disable the RemoteFX vGPU feature.
Deprecation: RemoteFX vGPU was removed with the release of Windows 10, version 1809 and Windows Server 2019.
Disablement: RemoteFX vGPU will be disabled in all applicable Windows platforms in the July 2020 Windows security updates (July 14, 2020).
Removal: RemoteFX vGPU will be removed from all applicable Windows platforms in the February 2021 Windows security updates (February 9, 2021)
In order to mitigate potential security risks within RemoteFX vGPU, we strongly recommend that users consider using an alternative vGPU technology.
Secure GPU virtualization is available through Discrete Device Assignment (DDA) in Windows Server LTSC releases (Windows Server 2016, Windows Server 2019) and Windows Server SAC releases (Windows Server, version 1803 and later versions).

Frequently asked questions
We will provide technical assistance for users who want to re-enable RemoteFX vGPUuntil February 2021. We will not continue to ship security or nonsecurity updates for RemoteFX vGPU.
If the VM is in a Saved state, you will see the following error message and will be required to remove the RemoteFX adapter to resume:
The virtual machine cannot be started because the server has insufficient GPU resources.
If the VM is in a Shutdown state, there is no error message.
If the VM is in a Start state, you will see an error message upon a Restart.
Secure GPU virtualization is available through Discrete Device Assignment (DDA) in Windows Server LTSC releases (Windows Server 2016 and Windows Server 2019) and Windows Server SAC releases (Windows Server, version 1803 and later versions). If you are on a Windows version earlier than Windows 10, version 1607, please consider upgrading.
