Today, I am going to show you how to create new source media that will slipstream the original source media, SQL Server 2008 R2 to SQl Server 2008 R2 SP1 then to SQL Server 2008 R2 SP1 CU3. Once
you have created this drop, you can install SQL Server 2008 R2 SP1 CU3 in a single step.
These instructions are for English SQL Server but will work with any language of SQL Server if you obtain the correct language.
Each time a new Service pack or CU is released, you can repeat these steps.
