Windows 10, version 1607, reached 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” shipset will continue to receive updates until January 2023 per the Microsoft Community blog.

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

Symptom Workaround After installing the March 13, 2018, or later cumulative update for Windows 10, version 1607, only the most-recent 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. Decline all feature updates on the WSUS server(s) except for the one that you want to deploy using ConfigMgr. Run another software-update scan cycle from the ConfigMgr control panel or wait until the client devices perform their next scan.
Microsoft is working on a resolution and will provide an update in an upcoming release.
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.
