Extended support for Windows Server 2016 will end on January 12, 2027. From this date onwards, Microsoft will no longer provide security updates, bug fixes, or technical support for this version. This can lead to significant security risks and restrictions in the operation of your IT systems—especially if important applications such as SEAL servers are running on them.
Why is the end of support so crucial for customers who use SEAL servers?
SEAL Systems AG operates its software solutions on Windows servers for many customers. With the end of support for Windows Server 2016, it is essential to also update the underlying server infrastructures. A SEAL server update is not a simple routine measure, but requires comprehensive planning and coordination.
We therefore recommend that you contact us as early as possible. This will allow us to work with you to plan the optimal timing and procedure for the update and ensure that everything runs smoothly. Only with timely preparation can you avoid operational disruptions or security breaches.
Overview of important dates for Windows Server versions
| Windows Server Version | Mainstream End of Support | Extended End of Support |
| Windows Server 2016 | January 11, 2022 | January 12, 2027 |
| Windows Server 2019 | January 09, 2024 | January 09, 2029 |
| Windows Server 2022 | October 13, 2026 | October 14, 2031 |
Customers who are still using older versions of Windows Server should be particularly vigilant, as support for products such as Windows Server 2012 R2 and 2008 has already expired.
