SQL SERVER 2012 SP2 Problem

Hello !

Some time ago, upgrade my SQL Server 2012 SP1 to SQL Server 2014. Not side-by-side installation, just upgrade ...
Today, in Windows update show SQL Server 2012 SP2 ??? Why ? Of course this update when start, show error.
If upgrade SQL Server to version 2014 why Windows Update show SQL Server 2012 SP2 version on avaliable updates ??

Thanks !
