What is new about the cumulative update KB4568831?

Windows 10 KB4568831 update

First of all, Microsoft disabled the RemotFX vGPU feature due to a security vulnerability related to  CVE-2020-1036 and KB4570006.

If you install this update and want to start a virtual machine with RemoteFX vGPU enabled, it will fail and you will receive an error message:

  • 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.

And if you want to enable the RemoteFX vGPU again, you will receive a message saying that the adapter is not supported anymore.

The conclusion is either you stop using this adapter or you install this update and it will block it. Otherwise you will be vulnerable to attacks exploiting the CVE-2020-1036 vulnerability.

Other changes coming with cumulative update KB4568831

Other improvements coming with the new update range from fixing issues with the Magnifier stopping to work in Internet Explorer to issues preventing family safety features.

Another notable fix is for an issue with 4K high dynamic range (HDR) content being displayed darker when you configure certain non-HDR systems for HDR Streaming.
