Version:

Security-only update

Summary

Learn more about this security-only update, including improvements, any known issues, and how to get the update.

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).

Verify that you have installed the required updates listed in the How to get this update section before installing this update. 

For information about the various types of Windows updates, such as critical, security, driver, service packs, and so on, please see the following article. To view other notes and messages, see the Windows Server 2012 update history home page.

Improvements

This security-only update includes new improvements for the following issues:

  • When you use Encrypting File System (EFS) files over a remote Web Distributed Authoring and Versioning (WebDAV) protocol connection, the connection might be unsuccessful.

  • Addresses a known issue that might prevent you from using the Wi-Fi hotspot feature. When attempting to use the hotspot feature, the host device might lose the connection to the Internet after a client device connects.

  • Addresses a known issue in which Windows Servers that use the Routing and Remote Access Service (RRAS) might be unable to correctly direct Internet traffic. Devices which connect to the server might not connect to the Internet, and servers can lose connection to the Internet after a client device connects.

For more information about the resolved security vulnerabilities, please refer to the new Security Update Guide website and the July 2022 Security Updates.

Known issues in this update

Symptom

Next step

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.

We are working on a resolution and will provide an update in an upcoming release.

How to get this update

Before installing this update

We strongly recommend that you install the latest servicing stack update (SSU) for your operating system before installing the latest Rollup. SSUs improve the reliability of the update process to mitigate potential issues while installing the Rollup and applying Microsoft security fixes. For general information about SSUs, see Servicing stack updates and Servicing Stack Updates (SSU): Frequently Asked Questions.

If you use Windows Update, the latest SSU (KB5016263) will be offered to you automatically. To get the standalone package for the latest SSU, search for it in the Microsoft Update Catalog

REMINDER If you are using Security-only updates, you will also need to install all previous Security-only updates and the latest cumulative update for Internet Explorer (KB5015805).
