Improvements and fixes
This update includes quality improvements. No new operating system features are being introduced in this update. Key changes include:
Addresses issue where Internet Explorer stops working when using F12-based developer tools.
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, Device Guard, 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.
For more information about the resolved security vulnerabilities, see the Security Update Guide.
Windows Update Improvements
Microsoft has released an update directly to the Windows Update client to improve reliability. Any device running Windows 10 configured to receive updates automatically from Windows Update, including Enterprise and Pro editions, will be offered the latest Windows 10 Feature Update based on device compatibility and Windows Update for Business deferral policy. This does not apply to long-term servicing editions.
Known issues in this update
After installing the March 13, 2018 or later Cumulative Update for Windows 10 version 1511, only the latest Windows 10 feature update is returned as applicable. This prevents the deployment of previously released feature updates using ConfigMgr (current branch) and Windows 10 servicing plans.
Microsoft recommends that you update to the latest, supported version of Windows 10, the Fall Creators Update (version 1709).
