Monthly Rollup

IMPORTANT Windows Server 2012 has reached the end of mainstream support and is now in extended support. Starting in July 2020, there will no longer be optional releases (known as "C" or "D" 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, seeCVE-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:

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.”

  • "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=2131976)”

As of February 11, 2020, Internet Explorer 10 is no longer in support. To get Internet Explorer 11 for Windows Server 2012 or Windows 8 Embedded Standard, see KB4492872. Install one of the following applicable updates to stay updated with the latest security fixes:

  • Cumulative Update for Internet Explorer 11 for Windows Server 2012.

  • Cumulative Update for Internet Explorer 11 for Windows 8 Embedded Standard.

  • The August 2020 Monthly Rollup.

Improvements and fixes

This security update includes improvements and fixes that were a part of update KB4565537 (released July 14, 2020) and addresses the following issues:

  • 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.

  • Addresses an issue in Universal Windows Platform (UWP) apps that allows single sign-on authentication when an app does not have the Enterprise Authentication capability. With the release of CVE-2020-1509, UWP applications might begin prompting the user for credentials.

  • Addresses an issue in Microsoft Edge IE Mode when opening multiple documents from a SharePoint site.

  • Addresses an issue in Microsoft Edge IE Mode that occurs when you browse using anchor links.

  • Addresses an issue with loading Browser Helper Objects in Microsoft Edge IE Mode.

  • Addresses an issue where certain applications that rely on the JScript Scripting Engine become unresponsive under load.

  • Addresses an issue in which error 0x8007000E can occur during a Windows Update scan.

  • Addresses an issue with printing to a local port that is configured as a Universal Naming Convention (UNC) path or a shared network printer. These ports no longer appear in Control Panel on the Ports tab of the Print Server Properties dialog box. This issue occurs after installing Windows Updates released between May 2020 and July 2020.

  • Security updates to Windows App Platform and Frameworks, Windows Graphics, Windows Media, Windows Shell, Windows Cloud Infrastructure, Windows Authentication, Windows Kernel, Windows Hybrid Cloud Networking, Windows Peripherals, Windows Network Security and Containers, Windows Storage and Filesystems, Windows File Server and Clustering, Windows Hybrid Storage Services, Windows SQL components, Microsoft Scripting Engine, and Windows Remote Desktop.

Known issues in this update

Symptom

Workaround

Certain operations, such as rename, that you perform on files or folders that are on a Cluster Shared Volume (CSV) may fail with the error, “STATUS_BAD_IMPERSONATION_LEVEL (0xC00000A5)”. This occurs when you perform the operation on a CSV owner node from a process that doesn’t have administrator privilege.

Do one of the following:

  • Perform the operation from a process that has administrator privilege.

  • Perform the operation from a node that doesn’t have CSV ownership.

Microsoft is working on a resolution and will provide an update in an upcoming release.
