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.


For a comprehensive list of end-of-service dates for all versions and editions of the Windows client and Windows Server operating systems, bookmark the Windows lifecycle fact sheet or use the Microsoft Lifecycle Policy search tool to find lifecycle information for all commercial Microsoft products. We also recommend you bookmark the Windows message center and follow @WindowsUpdate for the latest news and announcements.

Wonder what about Windows 10 version 1903 which has a end of support scheduled for December 8, 2020 - if it will get delayed.  


When will we know about 1903? We'd like to step up from 1803 -> 1903 -> 1909, but don't want to lose support mid transition due to 1903 still listed as EoS December 2020.


@NickPrime 1909 is basically 1903 v2

maybe that's why 1903 EOS won't get extended

What happened to the Windows lifecycle fact sheet? Why does it redirect to a Windows lifecycle FAQ? 

What happened to the handy table that listed every single variety of Windows 10 and included the end of service dates for each? Where can we find that information today?
