This sample script checks pre-requisite fixes for AlwaysOn in SQL Server 2012. These fixes are publicly documented in https://technet.microsoft.com/en-us/library/ff878487.aspx (Prerequisites, Restrictions, and Recommendations for AlwaysOn Availability Groups (SQL Server)), in section “Windows Hotfixes that Support AlwaysOn Availability Groups (Windows System)”.

Installing prerequisite fixes is not checked during configuration of SQL Server AlwaysOn, however may result in unexpected issues later.
