April 10, 2018—KB4093119 (OS Build 14393.2189)
OS Build 14393.2189
Windows 10 version 1607 will reach end of service on April 10, 2018. Devices running Windows 10 Home or Pro editions will no longer receive monthly security and quality updates that contain protection from the latest security threats. To continue receiving security and quality updates, Microsoft recommends updating to the latest version of Windows 10.
IMPORTANT: Windows 10 Enterprise and Windows 10 Education editions will receive six months of additional servicing at no cost. Devices on the Long-Term Servicing Channels (LTSC) will continue to receive updates until October 2026 per the Lifecycle Policy page. Windows 10 Anniversary Update (v. 1607) devices running the Intel “Clovertrail” chipset will continue to receive updates until January 2023 per the Microsoft Community blog.
Note The release also contains updates for Windows 10 Mobile (OS Build 14393.2189) released on April 10, 2018.

Addresses an issue with printing content generated by ActiveX in Internet Explorer.
Addresses additional issues with updated time zone information.
Addresses an issue where user accounts are locked when applications are moved to a shared platform using App-V (e.g., XenApp 7.15+ with Windows Server 2016, where Kerberos authentication isn't available).
Addresses an issue that might cause the App-V service to stop working on an RDS server that hosts many users.

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 1607, 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.
This issue is resolved in KB4103723.
How to get this update
This update will be downloaded and installed automatically from Windows Update. To get the standalone package for this update, go to the Microsoft Update Catalog website.
Important When installing both the servicing stack update (SSU) (KB4093137) and the latest cumulative update (LCU) from the Microsoft Update Catalog, install the SSU before installing the LCU.
