Microsoft released a new cumulative update for Windows 10 April 2018 Update. The new Cumulative Update (KB4493464) brings no new features but brings a lot of improvements, and bug fixes. You can read the official changelog below.
IMPROVEMENTS AND FIXES
- 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 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 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.
- After installing this security update, custom URI schemes for application protocol controllers may not launch the corresponding application for the local intranet and trusted sites in Internet Explorer.
- After installing this update, there may be problems using the Preboot Execution Environment (PXE) to start a device from a Windows Deployment Services (WDS) server configured to use the Variable Window Extension. This can cause the connection to the WDS server to end prematurely while the image is being downloaded. This problem does not affect clients or devices that do not use the Variable Window Extension.
