As with previous rollups, this one includes all previous update rollups and adds fixes from interim knowledgebase articles.  This rollup also resolves a number of issues that had not been previously documented in the knowledgebase. And...as if that weren't enough...Update Rollup 7 adds support for Windows 7, Windows Server 2008 R2 and SQL Server 2008 R2.
