Removing Option to Export To Word

I was able to remove several options to export on my reports by going to the reportserver.config file and commenting out several export types in the RENDER tag section.But I did the same for WORD but it still appears as an option.e.g.<!-- <Extension Name="WORD" Type="Microsoft.ReportingServices.Rendering.WordRenderer.WordDocumentRenderer,Microsoft.ReportingServices.WordRendering" Visible="false"/> -->Thoughts?BTW using SSRS 2012
