Microsoft has informed that the Windows 10 updates starting in July 2020 will disable RemoteFX vGPU feature because of a security vulnerability. It will result in Virtual Machines (VM) starting failure.
On attempt to start virtual machines, Microsoft will inform users that RemoteFX-capable GPUs are disabled. If user enables the RemoteFX vGPU manually, Microsoft will inform the user about the vulnerability.
IMPORTANT Starting in July 2020, all Windows Updates will disable the RemoteFX vGPU feature because of a security vulnerability. For more information about the vulnerability, see CVE-2020-1036 and KB4570006. Once this feature is disabled, attempts to start virtual machines (VMs) will fail, and messages such as the following will appear:
- “The virtual machine cannot be started because all the RemoteFX-capable GPUs are disabled in Hyper-V Manager.”
- “The virtual machine cannot be started because the server has insufficient GPU resources.”
If you re-enable RemoteFX vGPU, a message similar to the following will appear:
- “We no longer support the RemoteFX 3D video adapter. If you are still using this adapter, you may become vulnerable to security risk. Learn more (https://go.microsoft.com/fwlink/?linkid=213976)”
