When will WinCC OA support Windows Server 2025 and for which versions?

Answer:
WinCC OA will begin to support Windows Server version 2025 with the release of WinCC OA V 3.21 (Plan date: Nov. 2025).
From then, we also plan support the 2025 server version for WinCC OA V 3.20 with the follow up patch.

Please keep in mind:
1) We run ~70k automated tests every night to ensure the excellent quality of WinCC OA.
Every additional platform, which is fully supported, increases efforts considerably.

2) If you require a specific platform version and/or for a specific OA version or if you require e.g. a platform version to be longer supported, an individual, paid contract might be feasible.
