Microsoft announced at the end of last year that WSUS is now officially deprecated.
Microsoft said:
As part of our vision for simplified Windows management from the cloud, Microsoft has announced deprecation of Windows Server Update Services (WSUS). Specifically, this means that we are no longer investing in new capabilities, nor are we accepting new feature requests for WSUS. However, we are preserving current functionality and will continue to publish updates through the WSUS channel. We will also support any content already published through the WSUS channel.
What does this announcement mean for you?
Realistically, it probably doesn’t mean a whole lot, at least not any time in the near term or medium term. The reality is that Microsoft has barely touched WSUS in the past 15+ years, and they currently have no plans to remove it or stop publishing updates to the WSUS channel, so you can continue to use your WSUS for the foreseeable future.
As for BatchPatch, it continues to work with or without WSUS.
