SQL Server updates missing from WSUS I don't use WSUS for SQL Server patching because we have so many different compatibility issues, requirements and downtime OLA's that it makes it impossible to deploy anything in this way - not sure of many who can to be honest.

However, we have a custom DBA 'app' that I would like to develop a snap-in for that alerts the team to any new updates released by Microsoft for SQL Server (SP's, CU's, Hotfixes etc.)

I thought, hey, let's just hook into the WSUS database, poll for new updates and display them on a web page if they exist...

It works to a fashion, but I noticed that there is a lot of missing updates in WSUS from SQL Server. For example I'm not seeing SQL Server 2014 SP2 CU1 in there which was released recently, 2014 SP1 CU7 is not there, but CU8 is. 2012 SP2 and SP3 are not their either, as another example.

We sync WSUS half-hourly, and all SQL Server products are selected.

Any idea why some SQL Server updates aren't coming through to us via WSUS? IS this normal? Do Microsoft not publish everything through WSUS?
Actually there is a good microsoft article about it. I had the same problem and Microsofts solution fixed it.
