If you re-enable RemoteFX vGPU, a message similar to 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.”

Improvements and fixes

This security update includes quality improvements. Key changes include:

  • Addresses an issue that causes certain applications to stop responding when under load if they rely on the JScript Scripting Engine.

  • Addresses an issue that prevents you from installing some .msi apps. This occurs when a device is managed by a Group Policy that redirects the AppData folder to a network folder.
