MC1551897 - 60-Day Reminder: Windows 10 Enterprise LTSC 2021 will reach end of updates on January 13, 2027

On January 13, 2027, Windows 10 Enterprise LTSC 2021 will reach the end of mainstream support. The January 2027 Windows security update will be the last update provided during mainstream support. After that date, monthly security updates will continue only for Windows 10 Enterprise LTSC 2021 devices enrolled in Extended Security Updates (ESU).

To help keep your devices protected and supported, we recommend updating to the latest Long-Term Servicing Channel release, Windows 11 Enterprise LTSC 2024. If your organization cannot complete its transition before January 13, 2027, ESU options are available for up to three years to help keep eligible devices protected while you complete your transition. Learn more at Plan for Windows 10 Enterprise LTSC 2021 end of support.

For detailed lifecycle dates, see the Windows 10 Enterprise LTSC 2021 lifecycle page. For servicing and lifecycle resources, see Windows 10 release information, Lifecycle FAQ - Windows, and the Microsoft Lifecycle Policy search tool.
