Windows Server 2016 Essentials failing to get offered updates via Windows Update since July 2025.

Hi,

Dealing with an ongoing issue where Windows Server 2016 Essentials (other SKU's seem fine) not being offered updates via Windows Update anymore, message says "Up to date".  Manual updates via Update Catalogue work fine and although WS 2016 is ending support in Jan 2027 this is over a year away and while Server Migrations are happening in earnest end of first quarter next year it is not happening now. 

This can be replicated on a clean install on different hardware both Physical and Virtual.  Any later Service Stacks or Cumulative updates installed manually have not fixed the issue and neither does clearing "Softwaredistribution" or "Catroot2" etc...

Any feedback would be appreciated and confirmation of the issue from Microsoft would also help clarify the issue and potential fix.

Thankyou.
