Windows 10 April 2018 Update Gets Cumulative Update

Microsoft is releasing another cumulative update for the latest version of Windows 10, as well as some of the previous releases. The company is releasing update KB4338819, which includes some general fixes and security patches for Windows 10. There aren’t any notable fixes in today’s release, but it now lets developers debug WebView content in UWP apps with the Edge DevTools Preview app from the store.

Here is the changelog for KB4338819, which brings the build number up to 17134.165:

• Improves the ability of the Universal CRT Ctype family of functions to correctly handle EOF as valid input.
• Enables debugging of WebView content in UWP apps using the Microsoft Edge DevTools Preview app that’s available in the Microsoft Store.
• Addresses an issue that may cause the Mitigation Options Group Policy client-side extension to fail during GPO processing. The error message is “Windows failed to apply the MitigationOptions settings. MitigationOptions settings might have its own log file” or “ProcessGPOList: Extension MitigationOptions returned 0xea.” This issue occurs when Mitigation Options has been defined either manually or by Group Policy on a machine using Windows Defender Security Center or the PowerShell Set-ProcessMitigation cmdlet.
• Evaluates the Windows ecosystem to help ensure application and device compatibility for all updates to Windows.
• Security updates to Internet Explorer, Windows apps, Windows graphics, Windows datacenter networking, Windows wireless networking, Windows virtualization, Windows kernel, and Windows Server.

Microsoft has also released cumulative updates for Windows 10 version 1709, version 1703, version 1607, and the very initial version of the OS. All available through Windows Update right now.
