Windows 10 Build 15063.966 (KB4088782) Changelog:

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

  • Addresses issue with printing XML documents in Internet Explorer and Microsoft Edge.
  • Addresses issue where Internet Explorer stops working when using F12-based developer tools.
  • Updates legacy Document Mode cell visibility in Internet Explorer.
  • Addresses issue where Internet Explorer is unresponsive in certain scenarios when a Browser Helper Object is installed.
  • Addresses issue that causes online video playback to stop responding.
  • Addresses issue where, after installing KB4056891, KB4057144, or KB4074592 on a server, you may not be able to access SMB shared files in directory junction points or volume mount points hosted on that server. The error is “ERROR_INVALID_REPARSE_DATA”. As a result, editing some group policies using GPMC or AGPM 4.0 may fail with the error “The data present in the reparse point buffer is invalid. (Exception from HRESULT: 0x80071128)”.
  • Due to recent work with our antivirus (AV) partners, AV software has now reached a sustained level of broad compatibility with Windows updates. After analyzing the available data, we’re lifting the AV compatibility check for the March 2018 Windows security updates for supported Windows 10 devices through Windows Update. We’ll continue to require that AV software be compatible. Devices with known AV driver compatibility problems will be blocked from updates. We recommend that customers check installed AV software compatibility with their AV provider.
  • Security updates to Internet Explorer, Microsoft Edge, Microsoft Scripting Engine, Windows Desktop Bridge, Microsoft Graphics component, Windows Kernel, Windows Shell, Windows MSXML, Windows Installer, and Windows Hyper-V.

If you installed earlier updates, only the new fixes in this package will be downloaded and installed on your device.
