April Patch Tuesday Updates Are Live for Windows 10 Versions 1903, 1803, 1709, and Others

Microsoft has started releasing the scheduled Patch Tuesday security updates for several versions of the operating system, including the April 2018 Update and the Fall Creators Update. The latter hits its end of service deadline today as version 1703 will no longer receive updates for Home and Pro users. As reported earlier, the May 2019 Update (currently in the Release Preview ring) is also receiving Patch Tuesday security updates.

  • Provides protections against Spectre Variant 2 (CVE-2017-5715) and Meltdown (CVE-2017-5754) for VIA-based computers. These protections are enabled by default for the Windows Client, but disabled by default for Windows Server. For Windows Client (IT Pro) guidance, follow the instructions in KB4073119. For Windows Server guidance, follow the instructions in KB4072698. Use these guidance documents to enable or disable these mitigations for VIA-based computers.

  • 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 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 App Platform and Frameworks, Windows Storage and Filesystems, Windows Server, Windows Graphics, Windows Input and Composition, Windows Kernel, Windows Virtualization, Windows MSXML, and the Microsoft JET Database Engine.
