Here are the April Patch Tuesday release notes for Windows 10 May 2019 Update, and versions 1903, 1803 and 1709

Microsoft has just released April Patch Tuesday updates for all supported versions of Windows 10, including the upcoming May 2019 Update. The latest bi-annual update is available for Windows Insiders in the Release Preview ring since yesterday, and today’s patch will bump the build number to 18362.53 (KB4495666).

This new cumulative update is available for all Windows Insiders already running the preview build 18362.30, but the release notes don’t mention any fixes. Instead, Microsoft highlighted that users may encounter error “0x800705b4” when launching Windows Defender Application Guard or Windows Sandbox after installing this build.

The May 2019 Update will start rolling our to  all Windows 10 users next month, but Microsoft is still in the process of shipping the October 2018 update, aka Windows 10 version 1809. If you’re running this version of Windows 10, you’re getting the build 17763.437 today with the following fixes and improvements:

  • Addresses an issue that occurs when you enable per font end-user-defined characters (EUDC). The system will stop working and a blue screen will appear at startup. This is not a common setting in non-Asian regions.
  • Addresses an issue that may cause applications that use MSXML6 to stop responding if an exception was thrown during node operations.
  • Addresses an issue that causes the Group Policy editor to stop responding when editing a Group Policy Object (GPO) that contains Group Policy Preferences (GPP) for Internet Explorer 10 Internet settings.
  • Addresses an issue that may cause authentication issues for Internet Explorer 11 and other applications that use WININET.DLL. This occurs when two or more people use the same user account for multiple, concurrent login sessions on the same Windows Server machine, including Remote Desktop Protocol (RDP) and Terminal Server logons.
  • Security updates to Windows Datacenter Networking, Windows Server, the Microsoft JET Database Engine, Windows Kernel, Windows Input and Composition, Microsoft Scripting Engine, Windows App Platform and Frameworks, Windows Storage and Filesystems, Microsoft Graphics Component, Windows Virtualization, Windows MSXML, Windows SQL components, and Microsoft Edge.

The April 2018 Update, aka Windows 10 version 1803 is getting a new patch Tuesday with the build 16299.1087. Here’s what’s new in this cumulative update:

  • Addresses an issue that may cause applications that use MSXML6 to stop responding if an exception was thrown during node operations.
  • Addresses an issue that causes the Group Policy editor to stop responding when editing a Group Policy Object (GPO) that contains Group Policy Preferences (GPP) for Internet Explorer 10 Internet settings.
  • Addresses a stop error that occurs when attempting to start the Secure Shell (SSH) client program from Windows Subsystem for Linux (WSL) with agent forwarding enabled using a command line switch (ssh –A) or a configuration setting.
  • Addresses an issue that occurs when you enable per font end-user-defined characters (EUDC). The system will stop working and a blue screen will appear at startup. This is not a common setting in non-Asian regions.
  • Security updates to Microsoft Scripting Engine, Windows Input and Composition, Windows Graphics, Microsoft Graphics Component, Windows App Platform and Frameworks, Windows Storage and Filesystems, Windows Server, Windows Datacenter Networking, Windows Server, Windows MSXML, Windows Kernel, Windows Virtualization, and the Microsoft JET Database Engine.

Today also marks the end of consumer support for the Windows 10 Fall Creators Update (version 1709), which receives its last patch tuesday update today. Microsoft now recommends Windows 10 Home and Pro users to upgrade to a newer version of the OS, and we really invite you to follow this advice.
