Update rollup kb2775511 still required?

Greetings,

 A while ago there was a separate rollup KB 2775511. We added this to our task sequences when building Windows 7.

  As we install all current software updates via SCCM/WSUS onto our Windows 7 machines, is this update rollup still required in our task sequence i.e. does the current wsus catalog include all the fixes and therefore a separate rollup package is no longer necessary?

Thanks
