    Does it still help to deploy the Enterprise “Convenience” Rollup Update (KB3125574) even if Server 2008 R2 is fully patched to WUA and MBSA standards?

    1. Absolutely, w/ Windows Update (WUAU) you are only getting the Security updates. The Enterprise convenience rollup, you are getting all the memory leaks, performance, reliability and usability fixes.
