I recently answered a question on Twitter regarding the availability of Cumulative Update downloads for specific platforms.
Starting from SQL Server 2005, our Release Services team moved to an Incremental Servicing Model to deliver fixes for issues identified on current releases of SQL Server[s]. We now release a Cumulative Update package for a Service Pack periodically which contains all the fixes released since the RTM version of the Service Pack and hence the name “Cumulative Update”.
Now you click on the link mentioned in the picture below, you will get an option to download the packages associated for all the platforms.
I know this is quite trivial information but I have answered this question a few times and hence the post.
