  • After releasing a major version of SQL Server, say SQL Server 2008 R2 RTM, the product group continues to triage and fix some variable number of bugs reported by customers, our support organization, the field, etc. based on priority, number of people hitting it, impact/severity, and other criteria.  In order to release these fixes somewhat rapidly, they release cumulative updates that are a collection of all bugs fixed up to that point. 

    Ex:  CU1 for SQL Server 2008 R2 lists the 60-70 bugs fixed as part of the cumulative update

    After CU1 is released, the process continues and later (roughly 30-60 days) the next CU is released, in this case CU2, which includes all bugs from RTM to CU1 and those from CU1 to CU2, thus the "cumulative" name. 

    Applying CU's follows the same process as applying a service pack.  The steps are listed in the CU documentation listed above, but essentially you run the installer and select the instance(s) on which you want to apply the CU.
