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, Microsoft Graphics component, Windows Kernel, Windows Shell, Windows MSXML, Windows Installer, Device Guard, and Windows Hyper-V.
