Improvements and fixes

This update includes quality improvements. No new operating system features are being introduced in this update. Key changes include:

  • 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.
