Unable to install KB2546951

Getting a Code 84B30002. Yes I know, there already some threads that deal about this but Icouldn't find my answer....

From what I can understand, I'm trying to update a SQL SERVER 2008 SP3 patch on a SQL SERVER 2008 R2 SP3 which they are not compatible from what I can understand. (see bellow for details).

However, I'm not sure why I'm getting a prompt to update it in windows update (I'm using windows 8.1). Anyone have a clue ? it look like windows update should be smart enough to ignore that update.... 

Any fix / workaround to get rid of that update ?
