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.

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.
