We have heard your feedback and understand your need to focus on business continuity in the midst of the global pandemic. As a result, we have decided to delay the scheduled end-of-service date for the Enterprise, Education, and IoT Enterprise editions of Windows 10, version 1803. This means that security updates will continue to be released monthly until May 11, 2021. The final security update for these editions of Windows 10, version 1803 will be released on May 11, 2021 instead of November 10, 2020.
Security updates for Windows 10, version 1803 will be available via our standard servicing outlets: Windows Update, Windows Server Update Services, and the Microsoft Update Catalog. You will not need to alter your current update management workflows.
After May 11, 2021, devices running the Enterprise, Education, and IoT Enterprise editions of Windows 10, version 1803 will no longer receive security updates. Organizations should plan to update their devices to the latest version of Windows 10 to remain supported after this date.
