Release Date:

6/9/2020

Version:

Security-only update

IMPORTANT We have been evaluating the public health situation, and we understand this is impacting our customers. In response to these challenges, we are prioritizing our focus on security updates. Starting in May 2020, we are pausing all optional non-security releases (C and D updates) for all the supported versions of Windows client and server products (Windows 10, version 2004 down to Windows Server 2008 SP2).

There is no change to the monthly security updates (B release – Update Tuesday); these will continue as planned to ensure business continuity and to keep our customers protected and productive.

Improvements and fixes

This security update includes quality improvements. Key changes include:

  • Security updates to Windows App Platform and Frameworks, Windows Kernel, Microsoft Graphics Component, Windows Input and Composition, Windows Media, Windows Shell, Windows Cloud Infrastructure, Windows Fundamentals, Windows File Server and Clustering, Windows Hybrid Storage Services, and the Microsoft JET Database Engine.

For more information about the resolved security vulnerabilities, please refer to the Security Update Guide.

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.

After installing this update, certain printers might fail to print. The print spooler might throw an error or close unexpectedly when attempting to print, and no output will come from the affected printer.

You might also encounter issues with the apps you are attempting to print from. You might receive an error from the app or the app might close unexpectedly.

Note This issue might also affect software-based printers, for example printing to PDF.

This issue is resolved in KB4567521.

How to get this update

Before installing this update

Microsoft strongly recommends 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 are using Windows Update, the latest SSU (KB4562253) 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 11.
