Where Can I Download a Specific SQL Server Cumulative Update?

Microsoft has made a lot of changes to their servicing model for SQL Server over the years, specifically moving more towards Cumulative Updates and away from Service Packs as a means to deliver updates and fixes to SQL Server.

Enlarging the AdventureWorks Sample Databases
