Release Date:

6/18/2020

Version:

OS Build 19041.331

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.

For more information about the various types of Windows updates, such as critical, security, driver, service packs, and so on, please see the following article.

Note Follow @WindowsUpdate to find out when new content is published to the release information dashboard.

Highlights

  • Updates an issue that might prevent certain printers from printing, generate print errors, or cause apps and print spoolers to close unexpectedly.

Improvements and fixes

This non-security update includes quality improvements. Key changes include:

  • Addresses an issue that might prevent certain printers from printing. The print spooler might generate 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, such as receiving an error, or the app might close unexpectedly. This issue might also affect software-based printers, such as when printing to PDF.

If you installed earlier updates, only the new fixes contained in this package will be downloaded and installed on your device.

Windows Update Improvements

Microsoft has released an update directly to the Windows Update client to improve reliability. Any device running Windows 10 configured to receive updates automatically from Windows Update, including Enterprise and Pro editions, will be offered the latest Windows 10 feature update based on device compatibility and Windows Update for Business deferral policy. This doesn't apply to long-term servicing editions.

Known issues in this update

Workaround

Some apps utilize the ImeMode property to control the Input Method Editor (IME) mode for individual text entry fields to increase typing efficiency. Some IMEs in Windows 10, version 2004 (the May 2020 Update) might have issues using the ImeMode property with certain apps. For example, the input mode will not switch automatically to Kanji or Hiragana.

This issue is resolved in KB4565503.

The Local Security Authority Subsystem Service (LSASS) file (lsass.exe) might fail on some devices with the error message, “A critical system process, C:\WINDOWS\system32\lsass.exe, failed with status code c0000008. The machine must now be restarted."

This issue is resolved in KB4565503.

When using some apps, such as Microsoft Excel, users of the Microsoft Input Method Editor (IME) for Chinese and Japanese might receive an error, or the app might stop responding or close when attempting to drag using the mouse.

This issue is resolved in KB4571744.

Users of the Microsoft Input Method Editor (IME) for Japanese or Chinese languages might experience issues when attempting various tasks. You might have issues with input, receive unexpected results, or might not be able to enter text.

All IME issues listed in KB4564002 were resolved in KB4586853.
