Once again it’s Patch Tuesday and Microsoft today is releasing new cumulative updates for Windows 10 1809 and earlier supported versions. Here’s what to expect.

Microsoft today released a new round of Windows 10 cumulative updates for this month’s Patch Tuesday. There are new cumulative updates for all supported versions of Windows 10 and server. The security update for Windows 10 1809 aka October 2018 Update is available in the form of KB4493509. There are, of course, no new features to report, but there are several system fixes and other improvements.

This latest round of cumulative updates will bump your build to 17763.437 and includes the following list of 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.

All other supported versions of Windows 10 and Server received new updates today, too. This included build 18362.53 for Insiders running Windows 10 1903 May 2019 Update.  Just like other Windows 10 cumulative updates, you should receive these them automatically in the background. Or, to stay on top of things, head to Settings > Update & Security > Windows Update and check for updates.

Note that there are a couple of issues with this update. Make sure to read Microsoft’s release notes for the potential issues and workarounds.

Also, remember that if you do have an issue with this or any other series updates, you can roll them back. Read our article on how to uninstall Windows 10 cumulative updates.
