As you may already know, Windows 10 Version 1511 has already reached its end of support. However, the operating system continued to receive cumulative updates during its supplemental support time frame. Today, Microsoft finished releasing updates for version 1511.
The official announcement claims the following.
Many customers have reported that supplemental servicing for Windows 10, version 1511 has been just what they needed to adopt Windows as a service and update to newer, supported versions of Windows 10. If you are still in the process of updating to a current version of Windows 10, mark April 10, 2018 on your calendar—that will be the last day for supplemental servicing for Windows 10, version 1511 and the last day for general servicing for Windows 10, version 1607.
