Improvements and fixes

Addresses an issue that delays the on-screen keyboard from reappearing when an external keyboard or scanner is used with device. With this customization, an OEM can define the delay value. For more information, see On-screen keyboard delay.

Addresses issue where an AD FS server issue causes the WID AD FS database to become unusable after a restart. This might prevent the AD FS service from starting.
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.
Addresses issue in which WPF applications that are running on touch or stylus-enabled systems may stop working or stop responding after some time without any touch activity.
Security updates to Internet Explorer, Microsoft Edge, Microsoft Scripting Engine, Microsoft Windows Search component, Windows Desktop Bridge, Microsoft Graphics component, Windows Kernel, Windows Shell, Windows MSXML, Windows Datacenter Networking, Windows Installer, and Windows Hyper-V.
Note This update isn't available with express installation files for Windows Server 2016.
