IMPORTANT Release notes are changing! To learn about the new URL, metadata updates, and more, see What's next for Windows release notes.

IMPORTANT Windows 8.1 and Windows Server 2012 R2 have reached the end of mainstream support and are now in extended support. Starting in July 2020, there will no longer be optional, non-security releases (known as "C" releases) for this operating system. Operating systems in extended support have only cumulative monthly security updates (known as the "B" or Update Tuesday release).

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. After you install this update, attempts to start virtual machines (VM) that have RemoteFX vGPU enabled 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
